Grounding TelsiNex

3.2 Grounding TelsiNexYou need a grounding cable beforehand to ground TelsiNex. Once the TelsiNex chassis is mounted in a rack, connect the grounding cables.

The chassis ground connections require 12 AWG annealed solid copper conductors, bare or individually insulated with colored Polyvinyl chloride (PVC) listed by Underwriters Laboratories (refer to Telcordia document TA-TSY-000120).

Warning: This equipment must be grounded. Ensure that the chassis is connected to the earth ground during normal use. While installing the unit, always make the ground connection first.

All TelsiNex units must be grounded using the chassis grounding cable and lug provided. The grounding must be done to the nearest grounding bus bar or junction plate. Grounding must not be done to the steel racks or to the steel part of any other equipment. The grounding cable must be run to the nearest copper grounding busbar/ plate. Obtain and record the ground resistance of the site from the site in charge.

To connect a grounding cable:

1. In the chassis, locate the grounding stud with two bolts.

2. Attach the other end of the ground cable to the rack, the grounding busbar, or any appropriate earth ground.

Note: The connection between TelsiNex and earth ground point must have an electrical resistance of less than one ohm.

Powering On TelsiNex

This chapter helps you in taking appropriate safety measures before powering on TelsiNex and verifying proper functioning of the device.


• Section 5.1, “Ensuring Safety Before Powering On TelsiNex”

• Section 5.2, “Switching on TelsiNex and Verifying Proper Functioning”

• Section 5.3, “Testing TelsiNex as a Link”

Basic system configuration that is used for booting is stored in the flash file system. The system boots with the appropriate system image and an initial configuration is created with the information stored on the flash.

5.1 Ensuring Safety Before Powering On TelsiNexTo ensure safety before powering on TelsiNex, you must take the following precautions:

1. Check and ensure that the PSU toggle switches are in OFF position.

2. Check loading of the DC supply. As a thumb rule, DC supply must not be loaded more then 75 percent of its maximum capacity and it must have approximately 10 Amps of current available for TelsiNex.

3. Check that chassis earth is connected to the nearest ground point. Tug the wire to check that the connection is reliable.

4. Check for -48V on the power supply cable connector using a multimeter. Perform the check for both the power supply cables. The acceptable input DC voltage is between 40V and 70 V DC.


Switching on TelsiNex and Verifying Proper Functioning

5.2 Switching on TelsiNex and Verifying Proper Functioning

Switch on TelsiNex by turning on both the PSUs one by one using the respective toggle switches.

Note: Allow 30 seconds of time between the switch on operation.

There are two LEDs related to power supply which indicate proper power supply:

• 48 V yellow LED glows if input of 48V is available.

• 12 V green LED glows if the power supply card is fine and giving an output of 12V to the MCC2.

You can know the status of the system with the help of the following front-panel LEDs:

• POWER: Power On

• L SYS: Local System status

• R SYS: Remote System Status

• R TRUNK: Remote trunk Status

Figure 5.1 The LEDs on the Front Panel

The following sections explain in detail the significance of each LED status during booting and operation.



5.2.1 LED Status During BootingWhen TelsiNex is powered on or booted, it undergoes a self test called POST. It takes approximately three to four minutes for TelsiNex to get booted and complete the POST operation. During POST operation, LEDs may be off, green, or blinking. After POST is completed successfully, all LEDs will turn green. At this point you can start configuring TelsiNex.

Table 5.1 shows the status of the LEDs, significance of each LED during the boot-up process and POST, and recommended action in case of a problem.

Booting and Configuring Basic Parameters

This chapter guides you through the booting sequence of TelsiNex and helps you to configure basic parameters of the system through the CLI.


• Section 6.1, “Booting TelsiNex”

• Section 6.3, “Configuring Basic Parameters”

6.1 Booting TelsiNexTelsiNex booting is successful if POST is successful after you power on TelsiNex. The user then starts the terminal emulation program (TeraTerm or Hyper Terminal) on the computer and connects it to RS-232A or by computer running Telnet connected to Ethernet Port - 1. It displays the default configuration of TelsiNex.

After you power on TelsiNex, start the terminal emulation program on the computer. Observe the booting sequence of TelsiNex on the computer. It displays the configuration of TelsiNex.

6.2 Accessing TelsiNex Through TelnetTo access TelsiNex through telnet:

1. Click Start, then select Run.

2. Enter the telnet command followed by the IP address of TelsiNex. The CLI window opens. You can also use a telnet client like Putty.


Configuring Basic Parameters

3. Enter the default login name and password as admin.

6.3 Configuring Basic ParametersYou can configure the clock as internal, external, or derived based on the field requirement. However, irrespective of the type of clock set at one end, the remote TelsiNex must derive its clock from the bearer output of local TelsiNex.

You can also set the transparent channels according to the requirement and usage.

6.3.1 Setting the NameTo set the name for TelsiNex, use the following command:

set dcme serialnum <serialnum_string>

Here serialnum_string can be any 96 character box serial number. For example:

set dcme serialnum tel_north_region_32

6.3.2 Setting the ClockYou must set the local and remote clocks to trunk and bearer respectively. Configure the clock as internal, external or derived based on the field requirement. However, irrespective of the type of clock set at one end, the remote TelsiNex must derive its clock from the bearer output of local TelsiNex.

Booting and Configuring Basic Parameters 6-3


Setting the Local ClockTo set the main clock, use the following command:

set dcme clockselect <sys|ber|trk trunkId (1-16)>

You must always set the local clock to trunk, as shown in the following example;

set dcme clockselect trk 1

Setting the Remote ClockTo set the remote clock, use the following command:

set dcme remote clock <sys|ber|trk trunkId (1-16)>

You must always set the remote clock to bearer, as shown in the following example:

set dcme remote clock ber

6.3.3 Setting Transparent ChannelsSet the transparent channels according to the requirement and usage defined by the customer.



To set the local transparent channel, use the following command:

set poolinfo map transparent <trunkId (1-16)> <trunkChannelId (1-31)>

To set the remote transparent channel, use the following command:

Note: You must enable or disable the transparent channels in the same order at both the local end and the remote end.

For example, assume that you enter the following commands at the local end:

Ensure that you set the remote channels in the same order:

set dcme remote transparentchannel <trunkId (1-16)> <trunkChannelId (1-31)>

6.3.4 Setting PCM ModeThe customer defines the PCM mode. It can be PCM30 or PCM31. Both TelsiNex systems in a link must have the same PCM mode setting.

To set pcmmode to PCM31, enter the following command:

set dcme pcmmode 1

To set pcmmode to PCM30, enter the following command

set dcme pcmmode 2

set poolinfo map transparent 1 1

set poolinfo map transparent 1 2

set dcme remote transparentchannel 1 1

set dcme remote transparent channel 1 2

Troubleshooting 7-1

Troubleshooting

This chapter provides some troubleshooting tips.

7.1 Replacing the Power SupplyYou may need to replace the power supply if the power supply is defective. TelsiNex is equipped with dual supplies to provide redundancy. Both supplies are hot swappable and the system will continue to work normally with only one supply working.

A power supply defect is signalled by the front panel POWER LED, going red. The status of both power supply and failure of any one is reported on the NMS or terminal.

You can also ascertain the defective unit by observing the two LEDs on each of the power supply module. The failed supply module would have either one or none of the LEDs glowing. If the failure is at the supply source, then both the -48V (yellow) LED and the 12V(green) LED would be off. If the failure is at the power supply module, then the input -48V LED (yellow) would continue to glow while the 12V LED (green) would be off.

The two supplies can be plugged out or plugged in while the system is fully operational, without affecting the operational state. However, Telsima recommends that you perform the following steps while replacing power supplies:

1. Switch the ON/OFF toggle to OFF position to remove the supply. Note that this switch has a locking lever and cannot be switched ON/OFF inadvertently. To unlock the lever pull the lever. Then switch supply on or off.

2. Unscrew the two captive screws holding the supply in place.


Replacing the Power Supply

3. Using the captive screws as holding point, pull out the supply.

4. Insert the replacement unit in to the empty slot. Ensure that it is switched off. Guide the unit smoothly on the PCB guides within the enclosure. You may have to apply a little more pressure to ensure that the supply connector connects properly.

5. Tighten the captive screws. Ensure that the supply face plate is seated flush with the enclosure.

6. Connect the -48V supply cord to the new PSU unit. Observe that the -48V DC available LED glows.

7. Pull the PSU toggle switch lever to On position. Observe that the 12V supply LED glows. The glowing LED indicates that the supply is on and the line is working.
