T1600 FPC Function

FPCs house the PICs that connect the T1600 Core Router to network media. The main
function of an FPC is to connect the PICs installed in it to the other T1600 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 4 FPCs installed, the Packet
Forwarding Engines can forward up to 1600 million packets per second (Mpps) for all
packet sizes. The T1600 Core Router provides up to 800 gigabits per second (Gbps), full
duplex switching (1600 Gbps of any-to-any, nonblocking, half-duplex switching).
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 on other FPCs continues uninterrupted during this process.

T1600 FPC Slots

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.

T1600 FPC Components

Each FPC consists of the following components:
FPC card carrier.
One or two Packet Forwarding Engines, consisting of Layer 2/Layer 3 Packet Processing
ASICs, Switch Interface ASICs, T-series Internet Processor ASICs, and a Memory
Mezzanine Board (MMB) which includes the Queuing and Memory Interface ASICs.
Each Type 1 FPC has one Packet Forwarding Engine
Each Type 2 FPC has one Packet Forwarding Engine
