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)
Each FPC slot not occupied by an FPC must be covered by an FPC blank panel. An FPC
blank panel weighs 7.7 lb (3.5 kg).
