Removing an MX240 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 FPCtakes up two DPC slots on the MX240router. One FPC can be installed horizontally
in the front of the router. The FPCs are hot-insertable and hot-removable. 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 134 on page 304):
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.
