Removing a PTX5000 PIC

436
PICs are hot-insertable and hot-removable. When you remove a PIC, the packet transport
router continues to function, although the PIC interfaces being removed no longer function.
The PICs are located in the FPCs installed in the front of the packet transport router. A
PIC weighs approximately 5 lb (2.3 kg).
To remove a PIC:
Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the
1.
PIC. If the PIC connects to fiber-optic cable, have ready a rubber safety cap for each
transceiver and cable.
Attach an electrostatic discharge ESD grounding strap to your bare wrist, and connect
2.
the strap to one of the ESD points on the chassis.
Use one of the following methods to take the PIC offline:
3.
Press and hold the online/offline button until the PIC LED goes out (about 5
seconds).
Issue the following CLI command:
user@host> request chassis pic fpc-slot fpc-slot pic-slot pic-slot offline
Label the cables connected to the PIC so that you can later reconnect each cable to
4.
the correct PIC.
Disconnect the cables from the PIC. Immediately cover each transceiver and the end
5.
of each fiber-optic cable with a rubber safety cap.
WARNING: Do not look directly into a fiber-optic transceiver or into the
ends of fiber-optic cables. Fiber-optic transceivers and fiber-optic cable
connected to a transceiver emit laser light that can damage your eyes.
CAUTION: Do not leave a fiber-optic transceiver uncovered except when
inserting or removing cable. The safety cap keeps the port clean and
prevents accidental exposure to laser light.
Arrange the cable in the cable management system to prevent it from dislodging or
6.
developing stress points. Secure the cable so that it is not supporting its own weight
as it hangs to the floor. Place excess cable out of the way in a neatly coiled loop in
the cable management system. Placing fasteners on the loop helps to maintain its
shape.
