Removing a T320 PIC
240
PICs are hot-insertable and hot-removable. When you remove a PIC, the 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 router. A PIC weighs less
than 2 lb (0.9 kg).
To remove a PIC (see
Figure 106 on page
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).
For a PIC installed in a Type 1 FPC, use a tool—such as a flat-blade screwdriver—to
press the button slightly beneath the faceplate of the PIC. For a PIC installed in a
Type 2 FPC or Type 3 FPC, use a narrow-ended tool that fits inside the opening that
leads to the button.
Issue the following CLI command:
user@host> request chassis pic fpc-slot fpc-slot pic-slot pic-slot offline
For more information about the command, see request chassis pic.
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. If the PIC uses fiber-optic cable, immediately
5.
cover each transceiver and the end of each 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.
