! Keep tools and equipment away from walk areas.

! Do not wear loose clothing, jewelry (such as rings, bracelets, or chains), or other items that

could become caught in the equipment during handling and use.

! Use the equipment in accordance with its marked electrical ratings and product usage

instructions.

! Do not work alone if potentially hazardous conditions exist anywhere in your workplace.

! Equipment grounding should comply with local and national electrical codes.

! The ONLINE system requires a 15 amp to 20 amp, DC circuit breaker for each shelf input DC

power source. This circuit breaker should protect against short-circuit and overcurrent faults,

in accordance with local and national electrical codes.

! When installing systems at sites that have raised floors designed to accommodate power,

ground, and signal cables, you may need to remove floor panels to complete installation or

maintenance work. In instances where a floor panel is removed, you should, whenever

possible, replace floor panels immediately after you have finished working below the floor. If a

floor panel must be left open, exercise caution to prevent injury that may result from tripping

over or falling through the opening.

LASER LIGHT HAZARDS AND PRECAUTIONS

During normal system operation, the ONLINE system is completely enclosed, and operators and incidental

personnel are not exposed to optical energy. During maintenance and any other activity involving in-service

systems, i.e., when the front bezel is open, connectors are removed and the system is energized, there is

a risk of exposure to laser energy.

The following work practices were developed by the American National Standards Institute and represent

basic laser safety guidelines:

Install the equipment in compliance with appropriate local and national electrical codes.

! In the United States, use National Fire Protection Association (NFPA) 70 and the

United States National Electrical Code.

! In Canada, use the Canadian Electrical Code, part I, CSA C22.1.

! In other countries, use International Electrotechnical Commission (IEC) 364, parts 1

through 7.

WARNING! ONLINE circuit packs (CPs) process and carry laser light and canemit laser radiation. To prevent eye injury, never look into open fiber connectors.

WARNING! Only trained personnel are permitted to install or performmaintenance on the ONLINE system.


23/248

009-2003-084 1 - 5


ESD HAZARDS AND HANDLING PRECAUTIONS

Many ONLINE components are susceptible to damage from static electricity. You can generate static

voltages as high as 35,000 volts just by handling plastic or foam packing material or by sliding an electronic

assembly across plastic or carpeting. Failure to exercise proper electrostatic discharge precautions can

result in intermittent or complete failure of components.

To minimize the potential for ESD damage to electronic assemblies, always follow these guidelines:

! Always wear an ESD wrist or ankle strap when handling for unpacking assemblies.

! Ensure that the wrist or ankle strap makes good contact with your skin and that the straps

banana plug connector is fully inserted in the ESD connector on the shelf.! Check the resistance of the antistatic strap periodically. The resistance measurement should

be

1 megohms to 10 megohms. If the resistance is not within this range, replace the antistatic

strap.

! Do not remove CPs and other assemblies from static-shielding packaging until you are ready

to install them.

! Always place CPs component-side-up on an antistatic surface, in an antistatic card rack, or in

a static-shielding container.

! Whenever you remove a CP from a shelf, immediately place it in a static-shielding container,

even if the pack is defective and you are returning it.

! Always use the latch levers to lock CPs in the shelf. The latch levers prevent accidental

removal, help to provide proper grounding for the CPs, and help ensure that the CPs

connectors are fully seated in the backplane connectors.

CAUTION: No modifications should be made to the ONLINE system or associated

equipment without management or supervisory authorization.

WARNING! Do not view the end of a fiber with unprotected eyes. Fiber should onlybe viewed with an indirect image converter or with a filtered optical instrument ofoptical density sufficient to reduce exposure levels to below the appropriatemaximum permissible. Always cover the ends of unterminated fiber with spliceprotector end caps.

WARNING! Any damaged or missing optical safety labels must be reportedimmediately to supervisory personnel.

Do not allow CPs to be in contact with your clothing. The wrist strap only protects

the CP from ESD voltages on your body; ESD voltages on your clothing can still

cause electronic component damage.


24/248

1 - 6 009-2003-084


! When removing CPs, use the latch levers to unseat the CPs you are removing.

! When installing or removing CPs, avoid touching any part of the CPs except the latch levers

and faceplates. Never touch any components or connectors on the CPs.

ELECTRICAL HAZARDS AND PRECAUTIONS

ONLINE CPs can be removed and replaced (hot-swapped) while the system is running. There is no danger

that an electrical hazard or system damage will occur when removing and installing CPs.

Observe the following basic guidelines when working on the ONLINE system or other electrical equipment:

! Before beginning any procedure that requires access to the interior of the shelf, locate the

emergency power switch for the room where you are working.

! Never install equipment that appears to be damaged.

! Connect the equipment to 48V DC supply sources that are electrically isolated from an AC

source, and ensure that the 48V DC source is reliably connected to earth.

! Carefully examine your work area for possible hazards, such as moist floors, ungrounded

power extension cables, and missing safety grounds.

! Do not perform any action that creates a potential hazard to personnel or makes the

equipment unsafe.

CAUTION: The ONLINE system has been provided with a terminal for the

connection of an equipment-grounding conductor. Particular attention must be

given to the establishment and maintenance of a reliable, low-impedance path to

earth.

WARNING! Some of the CP connectors on the ONLINE backplane present an

electrical hazard (i.e. the voltage-current product in excess of 240 volt-amperes).Never reach into a shelf with a conductive tool or a bare hand when power isapplied to the equipment.

WARNING! Some equipment may have more than one connection to the DCsupply voltage. All connections must be removed to de-energize the equipment.

Disconnect all power and external cables before installing or removing a shelf.

Never assume that power has been disconnected from a circuit; always check beforehand.

009-2003-084 1 - 7


LIFTING PRECAUTIONS

Before installing the ONLINE system, ensure that your site is properly set up so you will not need to move

equipment later to provide direct access to power sources and network interface connections.

Whenever you lift or move any heavy object, observe the following precautions:

! Enlist the assistance of a second person when lifting the object; do not attempt to lift the objectby yourself.

! Lift the object slowly; avoid making sudden movements or twisting your body as you lift.

! Keep your back straight and lift with your legs. If you must bend down to lift the object, bend

your knees to reduce the strain on your lower back, and avoid bending at the waist only.

! Always disconnect all external cables before lifting or moving equipment.

Secure your footing when lifting the object; balance the lifted weight between your feet.

system.

Procedure Disclaimer

This procedure is intended solely as an outline of methodologies to be followed in monitoring and managing

ONLINE 7000/9000/11000 Transport Systems. It is not intended as a step-by-step guide or a complete set

of all procedures necessary and sufficient to manage ONLINE 7000/9000/11000 Transport Systems.

While every effort has been made to ensure that this procedure is complete and accurate at the time of

printing, the information that it contains is subject to change. CIENA is not responsible for any additions to

or alterations of the original document. Networks vary widely in their configurations, topologies, and traffic

conditions. This procedure is intended as a general guide only. It has not been tested for all possible

applications, and it may not be complete or accurate for some situations.

GENERAL GUIDELINES

Clearing of ONLINE 7000/9000/11000 Transport Platform alarm conditions may require the removal and

handling of CPs within the NE. You must take the following precautions when doing so to avoid damaging

the CP or losing track of the order of the connecting fibers.

! Always make sure you are properly grounded before touching any part of the NE.

Review CHAPTER 1, SAFETY GUIDELINES if you have not already.

! Clearly label each wire or fiber as you remove it from the CP. This ensures that you can

reconnect the lines correctly when you reinstall or replace the CP.

AIR FILTER INSPECTION AND REPLACEMENTThe ONLINE NE contains an air filter that meets a minimum dust arrestance of 80%.

The filters should be visually inspected every three months, and replaced if dirty. There are up and down

arrows on the filter indicate how the filter should be installed.

MAINTAINING FIBERS

The fibers used with the ONLINE NE must be clean and free of defects to ensure transmission. The

following sections contain guidelines about fibers:

! Guidelines for Handling and Working with Fibers

! Cleaning Fiber Ends and Bulkhead Connectors

Guidelines for Handling and Working with Fibers

Fibers are durable, but they can be damaged if they are not handled properly. CIENA recommends the

following guidelines when handling optical fibers:

! Do not remove fibers from their packaging until you are ready to connect them.

! Do not touch fiber ends with your hands.

! To avoid scratching or other damage, keep fiber ends capped when you expect to leave them

unconnected for an extended period of time.

! Handle the fibers carefully to avoid nicking or cutting the sheath and the optical fiber within it.

! Handle the fibers carefully; rough handling can fracture a fiber internally.

! Never allow a fiber to be crimped, and never route a fiber so that it has a bend tighter than a 2-

inch radius.

! Always use a fiber management tray to contain any extra fiber length.

! Do not attempt to clean fiber ends or bulkhead connectors using any methods or materials

other than the ones discussed in the next section.

Cleaning Fiber Ends and Bulkhead Connectors

This section explains how to clean fiber ends and bulkhead connectors. Fiber and fiber-socket cleaning is

a critical part of the ONLINE9000 system installation and maintenance process. Since a significant

percentage of transmission problems in fiber-optic systems is caused by dirty connections, you can simplify

the installation process and reduce the amount of troubleshooting necessary by carefully following theprocedures in this section.

CLEANINGAND CONNECTING FIBERS

Since a fiber end is more likely to become dirty after cleaning than a bulkhead connector is, it is best to clean

the bulkhead connector first.

CLEANINGA BULKHEAD CONNECTOR

The following materials are required for this procedure:

! ESD Grounding strap

! Kimwipes

! Aerosol can of compressed air

! Extension tube for aerosol can of compressed air

CAUTION: To prevent damage from electrostatic discharge, never touch any part of

the ONLINE system without wearing a known-good ESD grounding wrist or ankle

strap.

STEP 1: Wash and dry your hands thoroughly (use a low-lint towel, if available).

STEP 2: Remove the protective cap from the bulkhead connector (store the cap in a place where it is notlikely to collect dirt).

STEP 3: Perform the following steps to clear the nozzle and extension tube on the aerosol can ofcompressed air (see Figure 2-1 forStep 3 through Step 5):

a. Hold the can upright (vertically) with tube attached to the nozzle.b. Use a Kimwipe to clean the end of the tube.

c. Press the nozzle, and hold it down for a second or two.

d. Clean the end of the tube again with a new Kimwipe.

Figure 2-1. Cleaning a Bulkhead Connector with Compressed Air

STEP 4: While still holding the can in the upright position, grasp the extension tube and bend it slightlyso that the open end of the tube is higher than the top of the nozzle.

STEP 5: Position the end of the tube approximately -inch from the bulkhead connectors opening, andpress the nozzle for a short burst.

STEP 6: Set the can of compressed air aside.

!

CAUTION: Make sure the can remains upright at all times to prevent any of the aerosol

propellant from mixing with the air exiting the nozzle and tube. If any propellant is sprayed

into the bulkhead connector, it will cause damage when the fiber is in use.

!

CAUTION: To prevent dirt from being introduced into the socket, do not replace the cap on

the bulkhead connector. The cap is intended only for protecting the socket from damage and

from excessive exposure to dirt when it is unused for extended periods.

CLEANINGAND CONNECTINGA FIBER END

Use the procedure in this section to clean a fiber end. The following materials are required for this

procedure:

! ESD Grounding strap

! Kimwipes

! CLETOP fiber connector cleaner (NTTI Reel Type A Connector Cleaner)

! Isopropyl alcohol (99%)

! Optical fiber scope with 1.25-mm adapter (Noyes Fiber Systems OFS 300 or equivalent). A

2.5-mm adapter may also be required for client equipment.

STEP 1: Carefully remove the fiber from its package.

STEP 2: Unwind the fiber and inspect it for kinks or other damage (discard damaged fibers).

STEP 3: Remove the protective cap from one end of the fiber (store the cap in a place where it won'tcollect dirt).

STEP 4: Clean the fiber end with either the Kimwipe cleaning method or the CLETOP fiber cleaningdevice. Perform Step 5 for the Kimwipe method or perform Step 6 for the CLETOP fibercleaning device method. Follow local practice in choosing the cleaning method.

NOTE: You can use a CLETOP fiber cleaning device instead of the folded-Kimwipe cleaningpad. The procedure for using the CLETOP device is described in Step 6. If you do notuse a CLETOP device, go to Step 5.

STEP 5: To use the Kimwipe method to clean a fiber, perform the following step:

a. Holding two Kimwipes by their edges only, fold them in half three times so you have a 16-

ply cleaning pad (see Figure 2-2).

Figure 2-2. Folding Two Kimwipes to Form a 16-Ply Cleaning Pad

b. Hold the cleaning pad by its edges with one hand, and gently rub the fiber end against the

surface of the pad in an upward stroke (see Figure 2-3).

!CAUTION: Always hold the Kimwipes as close to their edges as possible to avoid

contaminating them with oil and dirt from your hands.

NOTE: As shown in Figure 2-5, any dirt particles in the area within the fiber cladding (the circlein the views) are unacceptable and must be removed before the fiber can be used. Ifthere are scratches or unremovable dirt particles in this area, the fiber must bediscarded since dirt or scratches inside the cladding will prevent the fiber ends fromaligning correctly. Large dirt particles outside the cladding area can also prevent correct

alignment, so these must also be removed. If possible, the fiber end should be spotless,as shown in the view labeled Clean fiber.

g. If the fiber is not acceptably clean, repeat the cleaning process in Step a through Step f,

reinspecting the fiber end.

h. If the fiber is still not acceptably clean, create two more Kimwipe cleaning pads (see

Step a). Dampen one with 99% isopropyl alcohol, and gently rub the end of the fiber against

it.

i. Use the dry cleaning pad you prepared in Step h to dry the fiber end immediately after

cleaning it. Do not allow the alcohol to air-dry on the fiber end.

j. If the fiber is still not acceptably clean discard it and use another fiber.

STEP 6: To use the CLETOP Device to clean the fiber end, perform the following four steps:

a. Press the lever on the side of the CLETOP device to expose an uncontaminated area of

the cleaning ribbon (see Figure 2-6).

Figure 2-6. Cleaning a Fiber End with a CLETOP Cleaning Device

b. Rotate the fiber end slowly while rubbing it against the cleaning ribbon in a downward

stroke, once in each slot (the correct stroke direction is shown on the label on the CLETOP

CHECKING BULKHEAD CONNECTORSFOR CLEANLINESS

The following procedure explains how to determine whether a bulkhead connector is acceptably clean and,

if it is dirty, how to clean it. The following materials are required to complete this procedure:! CLETOP 1.25 mm cleaning sticks.

STEP 1: Insert the end of a newly-cleaned fiber fully into the bulkhead connector.

STEP 2: Remove the fiber from the bulkhead connector, and inspect it with a fiber scope (see Step eand Step fofStep 5 in the Cleaning and Connecting a Fiber End section).

STEP 3: If the previously clean fiber is no longer acceptably clean, continue with Step 4 (if the fiber isstill acceptably clean, reinsert it in the bulkhead connector and ignore the rest of thisprocedure).

STEP 4: Remove a CLETOP 1.25 mm cleaning stick from its wrapper (Figure 2-7).

Figure 2-7. Removing a CLETOP Cleaning Stick from Its Wrapper

a. Open the end of the wrapper furthest from the cleaning fibers (see Figure 2-7).

b. Slide the open end of the wrapper far enough toward the opposite end of the cleaning stick

so that you can grip the end of the stick.

c. Grip the end the stick (opposite the end that has the cleaning fibers), and use your other

hand to slide the wrapper off and discard it.

d.

e. Gently insert the end of the cleaning stick into the bulkhead connector. Be sure the end you

insert has the cleaning fibers attached to it (see Figure 2-8).

!

CAUTION: Always handle the cleaning sticks from the end opposite the cleaning fibers. If you

happen to touch the cleaning fibers with your hands, break the stick, and discard it. Never use

a cleaning stick if the cleaning fibers have been in contact with anything other than the inside

of the wrapper.
