router function, except that the PIC no longer receives or transmits data.

Removing a PIC in an M40e Router

To remove a PIC (see Figure 109 on page 200):
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. For more information about ESD,
see "Preventing Electrostatic Discharge Damage to an M Series, MX Series, or T Series
Router" on page 232.
If the PIC has multiple cable connector ports, label the cable connected to each port,
3.
to make it easier to reconnect the cables correctly.
Use one of the following methods to take the PIC offline:
4.
Press and hold the PIC offline button until its failure indicator LED lights, which
usually takes about 5 seconds. The failure LED is usually red; for more information,
see the M40e Multiservice Edge Router PIC Guide. For the PICs that install on an
Type 1 FPCs, the offline button for each PIC is next to it on the FPC card carrier. For
the PICs that install on an Type 2 FPCs, the offline button is on the PIC faceplate.
Issue the CLI command:
user@host> request chassis pic fpc-slot fpc-slot pic-slot pic-slot offline
For more information about the command, see the Junos System Basics and Services
Command Reference.
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.
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
