Removing an M320 FPC

When you remove an FPC, the router continues to function, although the PIC interfaces
installed on the FPC being removed no longer function.
The router holds up to eight FPCs, which are installed vertically in the front of the router.
The FPCs are hot-insertable and hot-removable. An empty FPC1 or FPC2 weighs
15 lb (6.8 kg), and an empty FPC3 weighs 16 lb (7.3 kg). A fully configured FPC can weigh
up to 29 lb (13.2 kg)
To remove an FPC (see Figure 91 on page 177):
Have ready a replacement FPC or FPC blank panel and an antistatic mat for the FPC.
1.
Also have ready rubber safety caps for each PIC using an optical interface on the FPC
that you are removing.
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.
Label the cables connected to each PIC on the FPC so that you can later reconnect
3.
the cables to the correct PICs.
Use one of the following methods to take the FPC offline:
4.
Press and hold the FPC online/offline button. The green
begins to blink. Hold the button down until the LED goes out. The LEDs and
online/offline button for each FPC are located directly above it on the craft interface.
Issue the following CLI command:
user@host>request chassis fpc slot slot-number offline
For more information about the command, see the Junos OS System Basics and
Services Command Reference.
Disconnect the cables from the PICs installed in the FPC. If a PIC uses fiber-optic

cable, immediately cover each transceiver and the end of each cable with a rubber
safety cap. Arrange the disconnected cables in the cable management system, to
prevent the cables from developing stress points.
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.
