Understanding FPCs
Purpose Inspect the FPCs to ensure that they connect PICs to the rest of the router so that
incoming packets are forwarded across the midplane to the appropriate destination
port.
What Is an FPC The FPC is a component of the Packet Forwarding Engine. FPCs house the various
PICs used in the router.
The FPCs installed in the router depend on the platform and the PICs needed.
Table 45 provides some FPC characteristics for each router type.
For a listing of available FPCs and supported PICs, see the appropriate router
hardware guide and router PIC guide.
