SYSTEM NOTATION (NP, NP+, ...)
Hardware Constitution of NP, NP+, NP++, and Twin
According to system models or customer options installed on the system, a number of system specifications or func-tions available may differ from system to system; such are:
� Selectable scan times, MA values, FOV dimensions
� ‘Remote Tilt’ function
� Number of arrays of DAS/detector units, i.e., single or twin DAS/detector subsystem
� ...
However, the ‘HiSpeed’ series scanners are principally grouped into four, for which the following notations are givenrespectively:
‘NP’, ‘NP+’, ‘NP++’ and ‘Twin’In this ‘Diagnostics’ manual, these notations NP, NP+, NP++, and Twin are used to describe differences among thesefour groups and to make descriptions of this manual read simpler.
(However, ‘Twin’ is further grouped into two, that is, ‘NP+ Twin’ and ‘NP++ Twin’. In general outline,NP+ Twin systems are NP/NP+ systems with a twin DAS/detector, and NP++ Twin systems are NP++ systemswith a twin DAS/detector. These notations also will be used when required.)
The following table describes the constitution of the major hardware of NP, NP+, NP++, and Twin.

Total Gantry Revolu-tions
Indicates the Gantry rotation numbers in “Status” column. This indication can be resetusing getStats (section 1-11). The date when the counter was reset is displayed in “In-formation” column.
The rotation number is slightly less than the mechanical Gantry rotation counter locatednear the TGP board (a few %), because this software counter does NOT read all of Gpulse interrupt.
The data of rotation number is sent to the OC just when the Gantry stops.
Total Tube Spits Indicates total tube spits numbers currently.
This is automatically reset when performing Update system log –> Tube spits (sec-tion 1-27) at tube replacement.
IQ Performance Tool Status
This tools give us advance notice for IQ performance change.
For the system with V/R 5.5x or later, the two types of warm–up scan can be selected:
� Tube Warm–up: performs tube several warm–up scans. These can achieve 13% case temperature.
� Daily calibration (Warm up): performs conventional tube warm–up scans (tube warm–up scans:30% caseand calibration scans) plus IQ performance measurement scans. (For detail scan protocol, refer to IQperformance Measurement scan described below.)
So, whenever the daily calibration is performed, the IQ performance data are collected and analyzed automatically,and the results are stored in the file, then displayed on the “Status” column of the IQ Performance Tool Status. The“Information” means the date when the status has been determined.The three types of status are displayed:
� GREEN: displayed when the result is WITHIN allowable specifications. (Also refer to IQ performance toolspecifications.)
� YELLOW: displayed when the result is OUTSIDE OF allowable specifications. There is a possibility toaffect Image Quality. (Also refer to IQ performance tool specifications.)
� RED: displayed when the result is OUTSIDE OF allowable specifications. A serious Image Quality prob-lem might occur. (Also refer to IQ performance tool specifications.)
NoteThe results are stored as a vector file, so that they can also be seen using Scan Analysis, DD fileanalysis function. (For mA Smudge and Scan Time Smudge Only, they can not be seen, becausethe files can NOT be made.) The files is stored up to 5MB. In excess of 5MB, the directory of the files will be cleaned up whenexecuting this tool. Since the vector files of approx. 400 KB per daily calibration are created, 10 days’data can be stored. However calculation in Scan Analysis reduces data to be stored.

DAS Data Numerical Display Displays numerically raw data without any data correction orconversion applied; i.e., displays DAS data itself in hexadeci-mal format.
A Side For Twin System ONLY:GSA has a function to manipulate two raw data (A and B). So we can make mean file or
B Side raw file from each detector channel independently. It means, in every scan mode, the tworaw data (A and B) are corrected and used for reconstruction.
Raw Data File Selection
1. Select ‘Generic System Analyzer’ from ‘Diagnostics & analysis.’
2. Select a raw data ID from the lists:
a. Select first an Exam #.
b. Select a Series #.
c. Select an Acq #. If the selected series # above is for a helical scan, further select an Acq #.

� Fan Data Format – Correction & Conversion:Select whether the following corrections or conversion are to be applied or not.
– Offset File Correction: If ‘Yes’, the raw data is corrected by offset views (offset views are thefirst 64 views which are collected prior to x–ray exposure to gather offset data).
– Reference Correction: If ‘Yes’, the raw data is corrected by reference channel data (referencechannels receive direct x–rays, i.e., which have not passed through an object to be scanned).
– Natural Log Conversion: If ‘Yes’, natural log operation is applied to the raw data.
Then, the following data ‘Fan Data Averages’ are displayed:
– Active ViewsMax of Max = x.xxxxxx channel x view xMin of Min = x.xxxxxx channel x view xAvg of Mean = x.xxxxxxAvg of SD = x.xxxxxx

1-18 SCAN ANALYSIS
The scan analysis feature allows users to have interactive access to scan files collected on the scanner. Scan datato be viewed can come from either Patient Scanning or from service mode tools such as Diagnostic Data Collectionor Calibration.
Analysis is divided into three major areas of: SCAN ANALYSIS, dd FILE ANALYSIS, CAL FILE ANALYSIS, and Z–tracking (for Twin ONLY). dd FILE ANALYSIS and CAL FILE ANALYSIS is not yet available for this CT System. Eachmajor section provides an File List Select interface similar to the Image Works List Select, Image Browser. AnalysisList Select allows you to select the appropriate file of interest.
Any of the normal scan files may be selected for processing within Scan Analysis including Axial, Helical, and Scoutscans. Once the scan data of interest is selected you can select one of several processing options which include:Update, Scan Header, Cal Vectors, Plot MSD, Plot VVC, and Save Scan.
Definitions within Scan Analysis
� dd File (Diagnostic Data File):dd files are a result file from some type of operation on the scan data file. dd files are typically some formof view summed file that may have had some specific type of processing applied to it. For example, theprocessing applied to the raw data to calculate the position of the pin in ISO alignment results in a tempo-rary file that is a view summed result that could be saved as a dd file. As long as two dd files have the samenumber of data elements in them the two files may be added, subtracted, multiplied, or divided with eachother.
� Means and Standard Deviation File (MSD): This is usually the result of combining two or more views mathematically which results in Mean Valuesfor each channel in the views and an associated Standard Deviation for each channel in the views. In es-sence all of the user selected views in a scan file are summed together resulting in a single “master view”that contains the averaged data from all of the views. The mean values represent the average data valuefrom the channels and the standard deviation values represent the amount of variability for that channelsdata values across all of the views. The higher the standard deviation the more the channel output variedfrom view to view.
� Scan Header: This is the information contained within the Scan File that identifies the specific settings in affect whenthat scan file was created. The Scan Header includes information at several levels including: Exam, Se-ries, and Scan. Information identifying the technique selections, scan time, acquisition mode, and manyothers may be found in the scan header.
� Cal Vectors: Within Scan Analysis the Cal Vectors are only those vectors contained within the Scan Data File at thetime that the scan was taken.
� VVC (Views vs Channels): This is a way to graphically represent the data values from each channel for each view of data from theS–DAS as a shade of grey. The display will have the views stacked vertically and the channels arrangedacross the display horizontally.

The display will report the path and filename of the file just created. Once created,dd File can be viewed or compared with other files to check for specific operating characteristics.
� Plot MSD:Provides a set of view summed Means and Standard Deviation Plots of a scan file. The plotter is startedto display the means vectors and the standard deviation vectors, computed across the entire scan for eachdetector macro row. There will be (4) mean and standard deviation plot sets in the display window. After Plot MSD is started, a preprocessing option selection window appears:
– Offset Correction:This processing step removes from the scan data, the signal bias introduced by the acquisitionelectronics. This operation is performed on a channel by channel basis for each view.
– Reference Normalization: Makes use of unobstructed (not blocked by the patient) detector cells at the end of the detectorto adjust for fluctuations in the x–ray beam and effects of aperture size and mA. In the case wherethe reference channels are blocked, the system uses an estimated value for the processing. Thesteps for Reference Normalizing the scan data involves: Offset Correction for the ReferenceChannels, Dividing the Offset Corrected Scan Data by the Averaged Reference Channels foreach view.
– Log Conversion:The log operation is applied.
– Convolved Data: This processing step mathematically filters the channel data to remove blurring affects that wouldoccur when the views are back–projected. The affect is to ‘sharpen’ each channels data valuewithin the view. Without the convolution step, some of the x–ray attenuation data for a particularchannel ends up in the channels on either side of that particular channel. Convolution puts thatadjacent channel contribution back into the channel data that it should have been in to begin with.
Cursor reporting of data value and channel numbers is provided.For terminology and usage, refer to Generic System Analyzer.

Compare your System’s plots and analyze them relative to the speci-fication shown in each figure. The plots shown are UN–FILTERED views, which is the default option when they areplotted. A 20 point boxcar filter takes the 20 view average and then plots the data.
A value is not considered to be out of specification, unless the limit is exceeded for a sustained interval of 100 viewsor more. In the cases where specifications are not given, consider plots informational only.
To use the function “Save to File” , need to make a directory named “data” under root. Then after performing Saveto File, plot data is displayed and text file will be stored into data directory as named “TrackingVsScan.txt” (about 15KBsize). But it is not so useful because of text file.
It is recommended to remove the directory “data” after checking the TrackingVsScan.txt file for system stability.

dd Math Functions
dd math consists of the following functions:
� Add
� Subtract
� Multiply
� Divide
� Channel to Channel (Ch2Ch) difference
� Ratio of means vs. standard deviation
Perform: add, subtract, multiply, divide, and channel to channel difference operations on dd files. These operationsare only available for dd file types.
Add, Subtract, Multiply, Divide
Applies add, subtract, multiply, and divide between vectors in two dd files. The output file is a dd file with one of thefollowing suffixes:
� .add
� .dif
� .mul
� .rat
Operations can be performed on dd files in View orientation, Channel orientation, RTS orientation, and Cal orientation.
Currently, no dd type restrictions are applied to operations between dd files, as long as the dd vectors have the samenumber of elements. If one file has a single vector and the other file has multiple vectors the mathematical operationwill be applied multiple times using the single vector.Otherwise the mathematical operation will be applied component wise for the number of vectors in each file.
Channel to Channel Difference
Applies the following calculation to the data from the data set(s) in the dd files for View, RTS or Cal orientation.(X2–X1), (X3–X2), (X4–X3),...,(Xn–Xn–1)Where X is the data value for each channel.The output is channel to channel dd file with extension: .c2c

Class C Histogram and Filter Function for GE System Log
In addition to the standard viewing and search functions described above, the System Browser allows you to pro-duce a Histogram of the entire gesyslog and display the results in a graphical, bar chart format. An additional featureis to first apply a fixed filter to the entire gesyslog and then produce a graphical histogram of the filtered results.Additional Histogram and Filter Functions are planned to be added in later software releases based upon your andengineering’s inputs.
� HistogramIf the ‘Histogram’ button is selected, the System Browser processes the entire gesyslog, not just thebuffer pages currently being viewed. The current Histogram processing counts the number of times thatindividual software processes (programs) log messages to the gesyslog.The Histogram includes two different pieces of information for each line reported in the graph.
– The name of the item(s) found during the generation of the Histogram. In this example thenames of the processes reporting messages to the log are displayed next to the number of oc-currences in the form <process name>. The process names are the names reported in the ge-syslog Process: field.
– A bar graph showing the relative number of occurrences for the found items in descending orderfrom the most number found to the least number found.
� Filter (Filtered Histogram)If the ‘Filter Check Box’ is selected and then the ‘Histogram Button’, the System Browser will first applya filter to the gesyslog and then produce a Histogram of that result.The current fixed filter is a list of ‘key word strings’. In the future we will add additional filter sets basedupon field and engineering inputs.
SYSLOG – OC
When you select either SYSLOG OC, the System Browser will display the IRX SYSLOG Files on the respective com-puter. These are the logs normally found at /var/adm on the OC system.
Once again you may select one or more of the log files to view in the Options: window and then select the View FileButton to retrieve and display the requested information. The Search and Next, Previous, First and Last functionsoperate the same as for the basic gesyslog viewer.
IOS Logs
The IOS log files are created and updated by various scanner application software processes.These processes include: Image Browser, Image Database Read Server, Image Database Write Server, Image Serv-er, DICOM Server, Image Acquisition Server, Networking Server, Film Composer Log, Printer Server, Archive, Dis-play, and Filming.
The System Browser has the same operation and capabilities as those for viewing the IRIX SYSLOG files.

6-1-1 Theory of Wake–up Communication
(1) OC will start Wake–up communication by sending SysConfig CMD to TGP(MP). The purpose of thisis to make sure about communication between each processors and to make each processors knowthe current system configuration. The starting timing is one of followings:
– Just after OC is booted–up
– Just after receiving SysConfig Request from TGP(MP). TGP(MP) keeps sending SysConfigRequest to OC after booted–up until it receives SysConfig CMD from OC.
– When OC found the contents of SysConfig is changed.
If OC sends SysConfig CMD to TGP(MP) 3 times without successful, OC gives up communicationand output error message on gesyslog as below.
Failed to get response of system config.Code is 3
Even under this sitation, OC looks booted–up correctly except error above. But the time moving fromNew Patient Screen to Scan Edit Screen becomes extremely slowed down, which takes around 1minutes. Also, Confirm button is never activated.

(2) After TGP(MP) receives SysConfig CMD, it sends SysConfig CMD to TGP(GP), TGP(TP) and OGPand wait for the response from each processor. TGP(TP) and TGP(GP) reply for TGP(MP) by send-ing TG Status.
(3) After OGP receives SysConfig CMD, it sends SysConfig CMD to kV Control(JEDI) and CIF(DAS)..OGP will wait for their reply.
(4) KV Control(JEDI) and CIF will reply for OGP by sending TG Status. TG Status will include error infor-mation if there are. In case OGP cannot receive reply from kV Control or CIF in time, OGP put errorinformation on the TG Status which will be send to TGP(MP).
(5) OGP will send TG Status to TGP(MP) after it receives TG Staus both from kV Control and CIF or aftertimeout is detected to receive reply.
(6) TGP(MP) will send TG Status to OC after it receives TG Status from all of TGP(TP), TGP(GP) andOGP or after timeout is detected to receive reply.

Data from Detector is sampled synchronized with DAS TRIG signal. So DAS Data Path Trouble Shooting canbe separated into DAS TRIG signal trouble shooting and DAS Data troube shooting. DAS TRIG signal is oneof pre–requisite for DAS Data transfer.Refer to Illustration 6–2.
6-2-1 Pre–requisite
Communication path from OC to CIF, through TGP, Slip Ring and OGP, should be confirmed to work before thistrouble shooting. You can check the result of Wake–up communication for brief confirmation.

6-2 DAS DATA PATH (continued)
6-2-2 DAS TRIG Signal Troubleshooting
There are 3 sources of DAS TRIG signal. 1st one is Azimuth encoder, 2nd is Cradle encoder, 3rd is OGP itselfand last one is TGP. Each sources are selected by OGP and TGP depend on the Scan Type except TGP asbelow :
Azimuth Encoder : selected on Axial Scan, Helical and Cine ScanCradle Encoder : selected on Scout ScanOGP ; selected on Stationary ScanTGP : selected in case reset switch is pushed on TGP.
As described above, DAS TRIG signal line is used to send RESET from TGP to OGP.
If you encounter the trouble related to DAS TRIG signal, it is recommended to try various scan type and resettingOGP through TGP to identify which path is in failure as followings:
(1) At first, proceed Stationary Scan using Off Line Scan. To make it simplify, data pattern can be setas DAS pattern, Rotor and X–ray Off and Current Azimuth is suggested. In case you found the failure,most probable failure is CIF and cabling between CIF and OGP.
(2) Secondly, proceed Scout Scan using Off Line Scan. DAS pattern and Rotor Off is suggested. In caseit does not work, try (4) to check signal line between TGP and OGP. If it does work, most probablefailure is on Cradle Encoder and cabling between this and TGP. On TBLCON BD, there are not anycomponents for DAS TRIG, but just connect from CN9 to CN1. On TBL BD, there are one componentto change the signal type.
(3) Next, proceed Axial Scan using Off Line Scan. DAS pattern and Rotor Off is suggested. In case itdoes not work, try (4) to check signal line between TGP and OGP. If it does work, most probable fail-ure is on Servo Amp and cabling between Azimuth Encoder and TGP. On SUB BD there are not anycomponents for DAS TRIG, but just connect from CN5 to CN2.
(4) If you found problem in (2) or (3), try to reset OGP by pushing RESET switch on TGP and check OGPis corrected reset. After reset correctly, OGP shoud go to IDLE status, which is DS6 on OGP blinks.If OGP is not reset, DAS TRIG signal line between TGP and OGP has the problem. Between them,there are cable between TGP and Signal Brush board, Slip Ring, Signal CONN board and cable be-tween Signal CONN and OGP. In this case, it is suggested to change Signal CONN board tentativelyat first because there is another one on backside of Slip Ring, which is exactly the same and not used.

6-2-3 DAS Data Troubleshooting
For DAS Data trouble shooting, LED indication of each components are beneficial. it is recommended that toconfirm data path on rotating side using stationary scan at first. Proceed rotation scan as next step to confirmdata path on Slip Ring. Following is the LED status to help you identify whether DAS Data is coming or not. Thesestatus is based on Off Line Scan with Rotor Off, DAS Data as Normal mode.
LED of RF RCV is not based on DAS Data but based on carrier wave. So RF Output LED does not change evenin the case DAS Data is not available. But when carrier wave is sent correctly, DAS Data can be sent correctlyin most of the case through Slip Ring because of error correction mechanism between DTRF and DASIFN.

6-2-4 Data Path Troubleshooting under Intermittent Failure
In case DAS data itself is coming to OC with errors below, this means intermittent failure occurs during transferringraw data.
(1) ‘Corrected View Number of BADRAW’ which means bad views were found but it was successfully cor-rected during reconstruction process.
(2) ‘Uncorrected View Number of BADRAW’ which means bad views were found and it cannot be correct.Image was not displayed as the result.
To identify the failure under this situation, data encoding/decoding theory is useful. Next page shows the summeryof data format and what kind of information is appeared on LED or View End Mark. Please refer to DASIFN Sectionon Advanced Theory Of Operation for detail.
In case you can find the bit errors constantly on specific position like below, failure should be on parallel data line.Example below indicates 3rd bit in one set of 16 bits is always zero
0000 1111 0222 3333 4444 5555 4666 7777 8888 9999 8aaa
Parallel data line failure occurs on CIF, DTRF, DASIFN, DBPCI, cabling between CIF and DTRF or between DASIFNand DBPCI. It may happen most possibly on DBPCI because there are most complex circuit to handle parallel signal.

To identify which one is failed in Slip Ring andDTRF/DASIFN, you can bypass Slip Ring byfollowing procedure.
1. Disconnect the optic fiber from DTRF.2. Connect optic fiber which is from DASIFNdirectly with DTRF as showed above in dottedline.
Be sure that Rotation Switch on lower backsideof gantry is off and use stationary scan withcurrent azimuth for testing.

The following sequence occurs in the LED’s when the power switch is turned on:
1. The Power LED comes on.
2. The octal SCSI ID flashes briefly. The Least Significant Bit is next to the Power LED. Note that if the SCSI IDis zero, no LEDs flash.

4. Once the power–up sequence completes, the DASM CPU LED (second light from left) blinks regularly, indicatingthat the CPU is active and functioning normally.
Start Up Sequence
When the DASM–VDB interface module is powering up, it performs start–up diagnostics and other related actions.
At power–up, the DASM unit performs the following tests:
� EPROM checksum test
� MFP 68901 access test (the Multi Function Peripheral chip controls the serial port, timing, and I/O)
� SCSI register access test
� Static RAM test
� Dynamic RAM test
� DMA test
When the DASM CPU LED blinks continuously at about two flashes per second, the initialization sequence is com-plete, and the continuous self–test is in progress. The self–test runs until a SCSI command (a write to block 0 on theDASM) is sent by the host. This test signals an error condition by blinking the CPU, SCSI, and Personal Module Inter-face LEDs in tandem, continuously.

1-3-3-3 Self–Test Options
Once the start–up sequence is complete, the resident software reads the state of the DIP switch labeled SW1 on theDASM II–VDB board to determine whether further tests are enabled. To access SW1 you must first remove the topcover. Upon locating SW1 you will notice the numbers 0, 1, and 2 silk screened on the printed circuit board. The waySelf–Test executes is determined by the setting shown below:
Switch Position ContinuousMode
Serial Loop–back
Single Pass Single Pass w/Memory
Debug Mode
0 Closed Closed Open Open Open
1 Closed Open Closed Closed Open
2 Closed Closed Closed Open Open
� Continuous Mode:Is the default setting. After executing the start–up diagnostic, the resident software will continuously runthe VDB self–test. Self–test will continue until the first SCSI command is received by the DASM.
� Serial Loop Test:In this mode the VDB tests the RS422 Driver and Receiver. Prior to executing this, a special loop–backconnector on the front panel of the VDB, without the loop–back connector the test will fail.
The loop–back connector is made by simply adding two wires to a 25–pin Male ‘D’ connector: (pin 8 topin 9) and (pin 21 to pin 22).
� Single Pass:The start–up diagnostics execute once, as described in 1-3-3-2 Start–up Sequence. Please be awarethat when position 0 is open error and other messages encountered during start–up diagnostics are di-rected to the serial port. Otherwise the errors are encoded on the LEDs.
� Single Pass w/Memory:Is controlled by Bit 2. When open the DASM exercises the entire DRAM during the start–up diagnostics.The Single Pass w/Memory test can take several minutes to complete, this is why it is normally disabled.
� Debug Mode:When position 1 is open the program jumps to the I/O Monitor when a diagnostic error occurs. The I/OMonitor gives the basic tools to debug the hardware. Opening positions 0 and 2 allows the technicianaccess to the start–up diagnostic suite via the serial port.

1-3-3-4 Start–up Problem
To report diagnostic conditions, the LEDs on the DASM II–VDB front panel have a corresponding binary representa-tion. The illustration 1–7 below shows the value assigned to each LED. The section after the figure explains how theLEDs represent error codes. Note that this sections deals with error codes related to the DASM Controller, whereSection 1-3-3-5, VDB Error Codes, explains the method used to report an error from the VDB diagnostic.
DASM Controller LED Error Codes
Using LEDs 2 and 4, a binary code signals any of the conditions listed in Table 1–10. The Power light and PIF LEDsare not used to report diagnostic conditions.
The three LEDs permit a combined total of only seven error codes. To overcome this limitation, the codes are definedas a series of one or more patterns. Each pattern begins with all LEDs flashing briefly, to indicate the start of the num-ber sequence that follows.
For example, to display error code 12 (Failed SCSI Interface Test), the CPU LED displays the first digit (1), stoppingbriefly before the SCSI LED displays the second digit (2), as shown in Illustration 1–7.

The display of each digit lasts approximately four times the duration of the initial binary “7” (that is, the flash of allLEDs). The pattern then repeats. Only the significant digits for each error condition are listed in Table 1–8.

First, all three LEDs blink together for the duration of a single pass. This requires approximately 10–15 seconds.Then the specific error code blinks twice before the next pass begins, with all three LEDs blinking together as before.
The bit pattern of the error codes appears as a series of LEDs being turned on and off. The low order bit is first.
When two LEDs blink together, the bit value is 1.When only one LED blinks, the bit value is 0.
To see an example of an error code displayed in this way, do the following:
� Remove the loop–back connector from the front panel of the DASM II–VDB.
� SW 1 position 0 is closed.
� SW 1 position 1 is open.
� Now cycle the AC power on the DASM
� When the first pass of the DASM self–test has completed, the LED display begins. The expected erroris 5 (RS–422 port fail), and the LED sequence is:Least significant first:bit 0 = 2 LEDs on = 1 Value 1bit 1 = 1 LED on = 0bit 2 = 2 LEDs on = 1 Value 4bit 3 = 1 LED on =0

From left to right, the lights indicate the following:
� PIFPersonality Interface light indicates a data transfer from the Common Memory to the LCAM circuitry.
� SCSIThis light indicates the host is accessing the DASM via the SCSI bus, such as commands sent or datareceived.
� CPUThis light indicates that the DASM CPU is active and operating properly. It flashes continuously ( “blinks”on and off) following power–up.
� PWRPower Light indicates that the DASM is powered. If this light does not illuminate at power–up, you shouldfirst check the power cord connections.

1-3-4-2 Start–up Sequence
When the DASM II–LCAM is powering up, it performs start–up diagnostics and other related actions.
At power–up, the DASM Controller performs the following tests:
� EPROM checksum test
� MFP 68901 access test (the Multi Function Peripheral chip controls the serial port, timing, and I/O)
� SCSI register access test
� Static RAM test
� Dynamic RAM test
� DMA test
When the DASM CPU LED blinks continuously at about two flashes per second, the initialization sequence is com-plete.
If an error occurs, the error condition is reported by blinking the CPU, SCSI, and PIF LEDs in tandem followed by anerror code.
Powering On
The following sequence occurs on the front panel’s LEDs when the power switch is turned on:
1. The Power LED lights.
2. The octal SCSI ID flashes briefly. The Least Significant Bit is next to the Power LED. Note that if the SCSI IDis zero, no LEDs flash.
3. The three LEDs flash once and go out.
4. Once the power–up sequence completes, the DASM CPU LED (second light from right) blinks regularly, indicat-ing that the CPU is active and functioning normally.

Note: SW1 position marked “SP” is not used.
� Single Pass:Is the default setting, and is the only setting allowed when connected to a laser camera.The start–up diag-nostics execute once, as described in 1-3-4-2 Start–up Sequence.
� Continuous Mode:After executing the start–up diagnostic, the resident software will continuously run the LCAM self–test.Self–test will continue until the first SCSI command is received by the DASM. Please be aware that whenposition 0 is open error and other messages encountered during start–up diagnostics are directed to theserial port. Otherwise the errors are encoded on the LEDs.
� Single Pass w/Memory:Is controlled by Bit 2. When setting to “open”, the DASM exercises the entire DRAM during the start–updiagnostics. The Single Pass w/Memory test can take several minutes to complete, this is why it is normal-ly disabled.
� Debug Mode:When position 1 is open, the program jumps to the I/O Monitor when a diagnostic error occurs. The I/OMonitor gives the basic tools to debug the hardware. Opening positions 0 and 2 allows the technicianaccess to the start–up diagnostic suite via the serial port.

1-3-4-4 Start–up Problem
To report diagnostic conditions, the LEDs on the DASM II–LCAM front panel have a corresponding binary representa-tion. The illustration 1–8 below shows the value assigned to each LED. The section after the figure explains how theLEDs represent error codes. Note that this sections deals with error codes related to the DASM Controller, whereSection 1-3-4-5, LCAM Error Codes, explains the method used to report an error from the LCAM diagnostic.
DASM Controller LED Error Codes
Using LEDs 2 and 4, a binary code signals any of the conditions listed in Table 1–13. The Power light and PIF LEDsare not used to report diagnostic conditions.
The three LEDs permit a combined total of only seven error codes. To overcome this limitation, the codes are definedas a series of one or more patterns. Each pattern begins with all LEDs flashing briefly, to indicate the start of the num-ber sequence that follows.
For example, to display error code 12 (Failed SCSI Interface Test), the CPU LED displays the first digit (1), stoppingbriefly before the SCSI LED displays the second digit (2), as shown in Illustration 1–8.
Illustration 1–8 LED Error Code Sequence

“2”Long

The display of each digit lasts approximately four times the duration of the initial binary “7” (that is, the flash of allLEDs). The pattern then repeats. Only the significant digits for each error condition are listed in Table 1–13.
Note:The first error stops the start–up sequence immediately.

1-3-4-5 LCAM Error Codes
The following sequence is used to signal an error during the LCAM portion of the Self–test.
First, all three LEDs blink together for the duration of a single pass. This requires approximately 10–15 seconds.Then the specific error code blinks twice before the next pass begins, with all three LEDs blinking together as before.
The bit pattern of the error codes appears as a series of LEDs being turned on and off. The low order bit is first.
When two LEDs blink together, the bit value is 1.When only one LED blinks, the bit value is 0.
The Self–test runs in continuous mode when SW 1 position 0 is “open”. A single failure will cause a error code to flashrepreatedly on the LEDs. Although, other errors may occur during testing only the first one is displayed forever.
First all LEDs will blink together several times indicates a problem. Next, the error code is displayed serially, twicein the two leftmost LEDs.
The pattern is binary and takes 4 blinks for the complete code. When the two LEDs blink together, the bit value is1, when only blinks the bit is 0. The bit order is low to high.
Record the blink pattern in the number of LEDs blinking, 1 or 2.
Record them RIGHT to LEFT, to make them easier to interpret.
1 2 1 2 Subtract 1 from each digit to obtain the bit value.0 1 0 1 The value of the code is 5.

SECTION 2 – TEST PROGRAMS
2-1 SYSTEM POWER–UP SEQUENCE
The power–ON test program is used for OC self–diagnostics during the Power up sequence.
This test program has two categories; Power On Test and Off–line Test (Detailed Power On test).The Off–line test includes more detailed tests than power–on Test, and takes longer to run.The power–on Test is normally selected automatically when powering ON the system. The Off–line test can be usedby the field engineer to perform a more detailed analysis in the event of an error occurring on the system.
The power–on test is described in Section 2-2.
Even if errors occur during the power–on test, the test continues to be executed until it finishes, and the test log windowappears. You can confirm the problem by reviewing test log, then select either of the following:
� [H/W diag] : Go to [H/W diag Main Menu] for OFF–LINE test
NoteFor more detail, refer to 2-3 Off–line Test.
� [Startup] : The error is skipped and the power–on sequence proceeds so that the start–up screen will be shown onthe CRT monitor.
NoteWhen the start–up screen does NOT appear even if using the [Startup] command, the system mustbe shutdown using [shutdown] button in the desktop menu.
� [Shutdown] : The system runs the shutdown sequence, resulting in the system powered OFF automatically.

The following tests are performed during the power–on test.
� hinv Test:Checks that the devices which are listed in the reference file created during the Reconfig procedure areidentified as correctly installed on the operator console.
� SCSI Test:Performs ‘inquiry’ and ‘self–test’ on each SCSI device. A read and write test on the media is not performed.The tested devices are those which were listed during the Reconfig procedure.
� NPR Test:Performs an access test on memory devices installed on the NPR (NP Recon Engine) boards. As forNPRS boards, only the NPRS1 board is tested. Perform the off–line test ( described in Section 2-3) to testother NPRS boards.
� DBPCI Test:Performs an access test on the DAS Buffer Memory and registers.

2-3 OFF–LINE TEST
NOTICEWhen the interactive test or off–line test is completed, the system MUST be powered OFF([Exit] –> [OK]) to avoid accidental X–ray Exposure. That is because system reboot can NOTactivate the system reset line.
2-3-1 General
This is a test to verify that access to memory/register of NPR or DBPCI boards is performed with no error. In off–linemode, the following two modes exists.
� Stop mode:The test will stop when error occurs.
� Continue mode:The test will proceed without stop when error occurs. The error occurred can be checked by viewing errorlog after test. However, there is a much possibility that Memory/Register have been overwritten, so thatyou can NOT confirm which the error occurred in read phase or in write phase.
Each mode above contains the following three test methods. (You can edit them whenever you want.)
– Normal:All of the test items can be run. It takes approx. 60 minutes for the longest time. (This depends on hardware configuration.)
– Quick:A part of the test items can be run. It takes shorter than “Normal” to complete. It takes approx. 50 minutes for the longest time. (This depends on hardware configuration.)
– Manual:The test items can be manually selected to run the tests for the specific item to be desired.The default setting is the same one as “Normal”.
NOTICEDo not use the manual test until you perfectly understand each test items in the manual test.Some memories or registers contain access prohibitive areas. If you change this area acci-dentally, the system hung–up often occurred.

3-2 DIAGNOSTIC TESTS
There are three types of software diagnostics tests provided on the O2 workstation. Each is described below:
� Power–On Tests
� IDE Tests
Power–On Test
These run automatically on the major hardware components of the workstation each time it is turned on. If the testsfind a faulty part, the LED on the front of the system will be red and there will probably be an error message. See alsoProblem Diagnosis (Section 3-1).
IDE Tests
The Interactive Diagnostic Environment (IDE) tests are more comprehensive than the Confidence Tests, and takelonger (as long as 30–45 minutes) to run. See Integrated Diagnostic Environment (IDE) Tests on the SBC (O2) (Sec-tion 3-5).

3-3 RECOVERING FROM SYSTEM CRASH
In most cases, your system will recover from a system crash automatically if you reboot the system.If, however, you have lost data on your system disk, and you cannot communicate with your system using the mouseor keyboard, or over the network, follow these instructions. The instructions assume you have a backup tape of yoursystem that has been made using the System Manager backup tool, or with the /usr/sbin/Backup script. You also needa CD with your current IRIX operating system level. If you are recovering data from a tape on a remote tape device,you need to know the hostname, tape device name, and IP address of the remote system.
1. Use a pen tip or an unwound paper clip to press the RESET button located on the front panel (Illustration 3–3).
Illustration 3–3 Pressing the Reset Button
Silicon-Graphics
2. When you see the System Startup notifier (Illustration 3–4), click STOP FOR MAINTENANCE or press ESC.

3. From the System Maintenance menu, choose RECOVER SYSTEM, or type 4 on the keyboard. The SystemRecovery Menu appears (Illustration 3–5).
Illustration 3–5 System Recovery Menu
4. If you have a CD–ROM drive connected to your system and the IRIX CD, click LOCAL CD–ROM. Then clickACCEPT to start. Insert the CD when prompted. The system takes five minutes or more to copy the information.If you don RE-MOTE DIRECTORY.
5. When a notifier appears asking you for the remote hostname, type the system’s name, a colon (:), and the fullpathname of the CD–ROM drive, followed by /dist. For example, to access a CD–ROM drive. On the systemmars, you would type: mars:/CDROM/distAfter everything is copied from the CD to the system disk, you can restore your data from a recent full backuptape. The backup must be one that has been made using the System Manager backup tool, or with the /usr/sbin/Backup script.Tip: If you need to check something on your system during the restore process, you can get ashell prompt by typing sh at most question prompts.
6. If you have a local tape device, you see this message:
Restore will be from <tapename> OK? ([Y]es, [N]o): [Y]
tapename is the name of the local tape device.

7. If you have a remote (network) tape device, when no tape device is found, or when you answered ‘No’ to thequestion in the previous step, you see this message:
Remote or local restore ([r]emote, [l]ocal):
– If you answer ‘remote,’ you have chosen to restore from the network, and you must know the hostname, tapedevice name, and IP address of the remote system. You also need to know the IP address of your system. TheIP address, such as 192.0.2.1, always has four components separated by periods.– If you answer ‘local,’ you have chosen a tape device that is connected to your system, and you are promptedto enter the name of the tape device.
8. When you see the following message, remove the CD–ROM, insert your most recent full backup tape, then pressENTER.
Insert the first backup tape in the drive, then press <Enter>,[q]uit (from recovery), [r]estart:
There is a pause while the program retrieves several files from the tape describing the system state at the timethe backup was made. Then you see this message:
Erase /x filesystem and make new one (y,n)? [n]
It prompts you for every file system that was known at the time of the backup. Read the following to decide wheth-er to answer y or n.– If you answer n for no, the system tries to salvage as many files as possible. Then it uses your backup tapeto replace the files it could not salvage. Usually you should answer no, especially if your backup tape is not veryrecent. If the file systems were badly damaged, or the backup was from a different level operating system, youmay need to answer yes.– – If you answer y for yes, the system erases the file system and copies everything from your backup tape tothe disk. The system loses any information on that file system that you created between now and when you madeyour backup tape.
9. You see this message:
Starting recovery from tape.
After two or three minutes, the names of the files that the system is copying to the disk start scrolling. When therecovery is complete, you see this message:
Recovery complete, restarting system.
NoteIf your backup tapes were old, or you were changing your operating system level, you should reinstallthe operating system from the IRIX CD that came with your system after system recovery is com-plete. When you see the Startup System notifier, press ESC, or click STOP FOR MAINTENANCE.Then click Install System Software.

3-4 DISABLING THE SYSTEM MAINTENANCE PASSWORD
If you are in the System Maintenance menu, and you choose INSTALL SYSTEM SOFTWARE, RUN DIAGNOSTICS,RECOVER SYSTEM, or ENTER COMMAND MONITOR, you may be prompted for a password.
If you do not know the password, you can disable it by installing a jumper (a small cap that connects two pins) on thesystem board inside the workstation. The system board is located in the system module. To install the jumper, youmust first remove the system module and the PCI tray. Follow these steps:
1. Turn off the workstation by pressing the power button on the front.
2. Remove the system module by releasing the lever on the extreme left as you face the rear of the workstationand sliding the module out. See Section 1–6 System Module, of OC Tabl of the Component Replacement manual.
3. Release and remove the PCI tray. See Section 1–8 PCI Tray, of OC Tabl of the Component Replacement manual.
NOTICEBefore touching any of the components, attach the wrist strap to your wrist and to a metalpart of the chassis.
4. Remove the jumper from the system board in the location shown in Illustration 3–6.
You must remove the jumper if you choose to reset the PROM password.

3-5 INTEGRATED DIAGNOSTIC ENVIRONMENT (IDE) TESTS ON THE SBC (O2)
The IDE tests on the O2 are stand alone tests that must be run at the boot PROM level.
To run the O2 IDE tests from the OC, the user must first shut down applications. Next, cu into the SBC by openinga UNIX shell and typing: cu sbc. Once a serial connection has been established, the O2 must be shut down and re–started. Do this by logging into the SBC as root and typing the ‘halt’ command. Press ENTER when prompted to restartthe SBC. When the system begins start–up, a message appears giving the user the option of performing system main-tenance. Press ESC at this prompt to get to the System Maintenance Menu. Choose Option 3, Run Diagnostics.A hardware probe will be conducted and a default set of test scripts will be run automatically. This set takes approxi-mately 10 minutes to execute. Pass and failure information is updated to the screen.
When you run the tests, the following error message may appear. However, ignore this message.

(If more than one NPRS board are de-fective, you may follow this way.)
If you fall into a loopin this flowchart, callOn–line Center.
Illustration 4–1 shows a flowchart for troubleshooting the recon system.
Following the flowchart, if you find that an NPRS board seems to be malfunctioning, exchange the board with someother NPRS board which is installed on another slot. And then, repeat the test, and you may be able to judge morecorrectly whether the exchanged board is defective or not. In this case, if the exchanged board seems to be operatingnormally, or an other board seems to be malfunctioning, the NPRM board might be defective.

How to Identify Defective NPRS – I
Among the NPR – Internal Test programs, Table 4–2 lists a collection of test programs, each of which performs a testfor each DSP (Digital Signal Processor–two DSPs are equipped on one NPRS board) and indicates the result of eachtest by ‘PASS’ or ‘ERROR’. Therefore, by reading when ‘ERROR’ appears, a defective NPRS board can be identified.See Illustration 4–4.

In the test result example shown in Illustration 4–4, in Program 17, all the (four) tests passed. However, in Program18, the fourth test failed (as shown by an arrow); this indicates that the #2 NPRS board is defective, since one NPRSboard has two DSPs, and a test is executed on each DSP. (This test example is for a recon system where two NPRSboards are installed.)

How to Identify Defective NPRS – II
Table 4–3 lists a collection of another test programs. With these test programs, unlike the test programs listed in Table4–2, a defective NPRS board can not be identified by reading when ‘ERROR’ appears. The way to identify a defectiveNPRS board, if any of these test programs failed, is explained in the following.

Assume that the recon system has two NPRS boards, and that No. 41 test program failed.
Illustration 4–6 Test Edit Window
Select the test programNo. which failed, by[PRIOR] or [NEXT]. (Sliding switch can beused also to select thetest program.)
The number of DSPs equipped on NPRS boards. Inthis example, the number is 4. (NPRS boards: 2,and 2 DSPs per NPRS)
The test program starts from this DSP. In thisexample, the test starts from #1 DSP.(#1 DSP and #2 DSP are on #1 NPRS, and#3 DSP and #4 DSP are on #2 NPRS.)
For example, by setting ‘Start Slv No’ to 3, and setting ‘Slv Count’ to 2, the program only tests the two DSPs on the#2 NPRS board; the program does not test the #1 NPRS. Thus, by changing the ‘Start Slv No’ and ‘Slv Count’, a defec-tive NPRS board can be identified.

RAM Check
1. The gantry processor (U87) performs read/write checks of its internal RAM, the external RAM (U92), and thedual port RAM (U77).
2. If a RAM check error occurs, the processor will stay in a hang up state, with the ERRG, LPG, RQG LED’s lightingon the TGP board.
If no error occurs, the processor proceeds to the following step.
ROM Check
3. The processor performs a data sum check on addresses 0 ∼ BFFF of the external ROM (U112).
4. If a ROM check error occurs, the processor will stay in a hang up state, with the ERRG, LPG, RQG LED’s lighting.
If no error occurs, the LPG LED blinks, and the processor proceeds to the following step.
Gantry Rotation Check and Azimuth Counter Initialization
5. The gantry processor starts rotating the gantry to check that the operation can be normally performed.
a. If the SYS–OFF–MNL service switch (SW1) on the TGP board is set to OFF, the system waits until the switchis set to SYS or MNL, with the RQG and LPG LED’s alternately blinking.
b. If power is not supplied to the servo amplifier, the rotation check is terminated, with the ERRG LED lighting.
If any other abnormal conditions/operations are found, the rotation check is terminated.
To start the rotation check anew, resolve the problems, and power on or reset the TGP board.
6. The gantry rotates at 15 sec/Rev, and the processor initializes the gantry azimuth counter with the GPLS1 signal.

If no error occurs, the LPT LED blinks, and the processor proceeds to the following step.
Gantry Display and Switch LED Check
5. The processor sequentially displays test characters (numbers) on the gantry display, and at the same time, se-quentially lights gantry panel switch LED’s.Refer to the Rotational Operation section of Gantry, of the Functional Check / Adjustment manual.
Gantry Tilt and Table Up/down Relay Check
The gantry tilt or table up/down operation is performed by a pump/valve mechanism which is powered by AC 115 V.This power is conveyed through two relays connected in series on SUB BD. Refer to Illustration 2–1. With theseconnections, if one relay of the two failed (that is, always closed), the power flow can be cut off by the other relay.This check verifies these relay operations.
6. The processor closes one relay which is controlled by the enable lines, and verifies that the gantry tilt or tableup/down does not take place.
If the operation takes place, the other relay (direct) is considered to be failed (closed), since any key on the gantryswitch panel is not pressed while the relay (enable) is activated; and an error message is displayed on the opera-tor console (OC).
7. An LED blinks on the gantry switch panel, and then press the key with the LED blinking.
If the corresponding operation takes place, the other relay (enable) is considered to be failed (closed), since theprocessor does not activate the relay (enable) while the key is pressed; and an error message is displayed onthe OC.

SECTION 4 – ERROR MESSAGE
4-1 ERROR MESSAGE
The errors described in Table 4–1 through 4–53 are detected by the TGP, OGP, or CIF board. When an error occurs,the error information is sent to the operator console (OC) using the Status communication.
Error with no Error Message
If either of the following errors occur, the microprocessor on the TGP or OGP board are forced to run in an infiniteloop, and no error message is sent to the OC.
� RAM, ROM check error:These checks are performed during a power–up sequence.
� Processor hang up:This is detected by the watchdog timer at intervals of 10.9 msec.

4-1 ERROR MESSAGE (continued)
Error Class
The errors detected by the TGP, OGP, or CIF board are either classified as Error Class, or Information Class, accord-ing to below:
� Error:If an error of this ‘Error’ class occurs during a scan, the scan is aborted, and an error message is displayedon the OC monitor.
� Information (written as ‘Infor.’ in Table 4–1 ∼ 4–53):If an error of this ‘Information’ class occurs during a scan, the scan will be continued, and an error messageis not displayed on the OC monitor.
Communication via Slip Rings (RS422)
The scan processor on the OGP board communicates with the management processor on the TGP board via sliprings.Normally, when one of the two processors receives communication data from the other processor, the receiving proc-essor checks a checksum data, and sends back an ACK message to the sender, if the data is OK; otherwise, sendsback a NACK message. When the sender receives this NACK message, it resends the data. If this repeats threetimes (three NACK’s), the communication is regarded as an error. If the receiver does not send ACK nor NACK withina specified time, this also is regarded as an error communication.

2-4 ERROR REPORTING
Np system only gets the simplified error code from the Jedi generator.
The Np system errorlog adds to the simplified error code the following information :
� error message (refer to the Np system documentation)
� system phase : state of the system when the error occurred. Take care, the system state may bedifferent to the generator phase (refer to the Np system documentation)
� system time : date and time when the error occurred. Take care, the system time may be differentto the generator time
Whenever a generator error is logged in the system errorlog file and displayed on the operatorconsole, the Jedi errorlog upload functionality is available to get more detailed information about theerror.
This function must be performed from the operator console.
The simplified error code must be used to find the Jedi error code in the Jedi errorlog file.
Having these two information, look at the Jedi trouble shooting table to find the FRU to replace.
Error codes can also be read by connecting the laptop

Warning errors are the result of automated and regular background monitoring for either softwareevents or voltages threshold overtaking.
Those errors are merely for engineering usage and do not indicate any hardware error failure.
However, as they are logged into the Generator Err_log file, just as the previous list of error, they arelisted here to help error sorting out.
Should too many of them are seen when viewing error log, it is advised to report them via CQA, sincethe equipment is still operating.

Purpose :
The purpose of this test is to drive the heater inverter(s) on both filaments and all the tubes connectedto the generator in order to identify a faulty heater FRU or a wrong connection between heater board,HV Tank and tube(s). HV function and Rotation function are disabled during this test.
Pre–requisites :� kV control board alive and running : S0–S7 Leds are lit successively or a combination of them blink
� heater board alive and running : DS1 and DS2 Leds are lit successively
� heater DC supply present : DS3 Led is lit
Test type : No manual interaction
Sequence :
Once selected the tube the test is running on , start the diagnostic.
The following sequence runs on the small focus and then on the large focus :
� 5 seconds preheat
� 0,4s boost
� 5s heat ( focal spot max current – 1Amp )
There is 10s stop time between each focal spot run
During the test , the heater safeties are checked the same way than in application mode

4-4-1 NP Generator Error Reporting
Np system only gets the simplified error code from the Jedi Generator.The Np system errorlog adds to the simplified error code the following information:
� error message (refer to the Np system documentation)
� system phase : state of the system when the error occurred. Take care, the system state is different ofthe Generator phase (refer to the Np system documentation)
� system time : date and time when the error occurred. Take care, the system time is different of the Genera-tor time
Whenever a Generator error is logged in the system errorlog file and displayed on the operator console, the Jedi error-log upload functionality is available to get more detailed information about the error.This function must be performed from the operator console.The simplified error code must be used to find the Jedi error code in the Jedi errorlog file.Having these two information, look at the Jedi trouble–shooting table to find the FRU to replace.
Error codes can also be read by connecting the service laptop.
4-4-2 Tiger Generator Error Reporting (not for NP++ and Twin systems)
Tiger console only displays the simplified error code from the Jedi Generator.
Whenever a Generator error is displayed on the operator console, the Jedi errorlog upload functionality is availableto get more detailed information about the error.This function must be performed from the service laptop.The simplified error code must be used to find the Jedi error code in the Jedi errorlog file.Having these two information, look at the Jedi trouble shooting table to find the FRU to replace.

Warning errors are the result of automated and regular background monitoring for either software events or voltagesthreshold overtaking.Those errors are merely for engineering usage and do not indicate any hardware error failure.
However, as they are logged into the Generator Err_log file, just as the previous list of error, they are listed here tohelp error sorting out.
Should too many of them are seen when viewing error log, it is advised to report them via CQA, since the equipmentis still operating.
