Up to eight FPCs install vertically in the front of the PTX5000. The FPC slots are numbered
FPC0 through FPC7 , left to right. If a slot is not occupied by an FPC, an FPC blank panel
must be installed to shield the empty slot and to allow cooling air to circulate properly
through the packet transport router.
FPCs house the PICs that connect the PTX5000 to network media. The main function
of an FPC is to connect the PICs installed in it to the other chassis components. The
Packet Forwarding Engine receives incoming packets from the PICs installed on the FPC
and forwards them through the switch planes to the appropriate destination port.
When you install an FPC into a functioning PTX5000, the Routing Engine downloads the
FPC software, the FPC runs its diagnostics, and the PICs housed on the FPC are enabled.
Forwarding on other FPCs continues uninterrupted during this process.
