Removing an MX480 FPC
When you remove an FPC, the router continues to function, although the PIC interfaces
installed on the FPC being removed no longer function.
An FPC takes up two DPC slots on the MX480 router. Up to three FPCs can be installed
horizontally in the front of the MX480 router. The FPCs are hot-insertable and
hot-removable. An empty FPC3 weighs 14 lb (6.5 kg). A fully configured FPC can weigh
up to 18 lb (8.2 kg). Be prepared to accept its full weight.
To remove an FPC (see Figure 141 on page 334):
1. Have ready a replacement FPC or FPC blank panel and an antistatic mat for the FPC.
Also have ready rubber safety caps for each PIC using an optical interface on the FPC
that you are removing.
2. Attach an ESD grounding strap to your bare wrist and connect the strap to one of the
ESD points on the chassis.
3. Label the cables connected to each PIC on the FPC so that you can later reconnect
the cables to the correct PICs.
4. Use one of the following methods to take the FPC offline:
•
Press and hold the FPC online/offline button. The green OK LED next to the button
begins to blink. Hold the button down until the LED goes off. The LEDs and
online/offline button for each FPC are locateddirectly 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 CLI Explorer.
