Up to eight FPCs install vertically in the front of the router. The FPC slots are numbered
through , left to right. If a slot is not occupied by an FPC, an FPC blank panel
FPC0 FPC7
must be installed to shield the empty slot and to allow cooling air to circulate properly
through the router.
FPCs house the PICs that connect the T4000 Core Router to network media. The main
function of an FPC is to connect the PICs installed in it to the other T4000 router
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. In a maximum configuration with eight Type 5 FPCs installed, the Packet
Forwarding Engines can forward up to 4000 million packets per second (Mpps) for all
packet sizes. The T4000 Core Router provides up to 2000 gigabits per second (Gbps),
full duplex switching (4000 Gbps of any-to-any, nonblocking, half-duplex switching).
