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 118 on page 285 ):
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.
