FPCs house the PICs that connect the T320 Core Router to network media. The main
function of an FPC is to connect the PICs installed in it to the other 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 FPC3s installed, the Packet Forwarding Engines
can forward up to 385 million packets per second (Mpps) for all packet sizes. The
maximum aggregate throughput rate for the router is 160 Gbps (full duplex).
FPCs are hot-removable and hot-insertable. When you remove or install an FPC, packet
forwarding is not interrupted. When you install an FPC into a functioning router, the
Routing Engine downloads the FPC software, the FPC runs its diagnostics, and the PICs
housed on the FPC are enabled. Forwarding continues uninterrupted during this process.
Up to eight Flexible PIC Concentrators (FPCs) install vertically in the front of the T320
Core Router (see Figure 22 on page
FPC0 to FPC7 . Each FPC has two connectors into which a PIC can be installed, allowing
62). The FPC slots are numbered left to right from
