Removing A Ptx5000 Pic - Juniper PTX5000 Hardware Manual

Removing a PTX5000 PIC

PICs are hot-insertable and hot-removable. When you remove a PIC, the PTX5000 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 PTX5000. A PIC weighs approximately 5 lb
(2.3 kg).
To remove a PIC:
1. Place an electrostatic bag or antistatic mat on a flat, stable surface to receive the PIC. If the PIC
connects to fiber-optic cable, have ready a rubber safety cap for each transceiver and cable.
2. Attach an electrostatic discharge ESD grounding strap to your bare wrist, and connect the strap to
one of the ESD points on the chassis.
3. Use one of the following methods to take the PIC offline:
• 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
4. Label the cables connected to the PIC so that you can later reconnect each cable to the correct PIC.
5. Disconnect the cables from the PIC. Immediately cover each transceiver and the end of each fiber-
optic cable with a rubber safety cap.
LASER 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.
6. Arrange the cable in the cable management system to prevent it from dislodging or 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.
