    T1600 Flexible PIC Concentrator (FPC) Description

    FPCs are hot-removable and hot-insertable.

    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 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 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
      • Each Type 3 FPC has two Packet Forwarding Engines
      • Each T640-FPC4-ES has one Packet Forwarding Engine
      • Each T640-FPC4-1P-ES has one Packet Forwarding Engine
      • Each T1600-FPC4-ES has two Packet Forwarding Engines
    • Processor Mezzanine Board (PMB), which includes a 300-MHz CPU, system controller, 256 MB of SDRAM, and two Fast Ethernet interfaces.
    • Two LEDs, located on the craft interface above the FPC, that display the status of the FPC.
    • FPC online/offline button, located on the craft interface above the FPC.

    T1600 FPC Terminology

    Regardless of whether you are holding an FPC vertically or horizontally, this document uses the same terms for all four edges of the FPC (see Figure 1):

    • Faceplate—Edge of the FPC that has slots into which you insert the PICs
    • Connector edge—Edge opposite the faceplate; this edge has the connectors that attach to the midplane
    • Top edge—Edge at the top of the FPC when it is vertical
    • Bottom edge—Edge at the bottom of the FPC when it is vertical

    Identifying the T1600 FPCs

    Check the label on the faceplate to identify the FPC. For FPCs without a label on the faceplate, check the location of a PIC's offline button and how the PIC is secured to the FPC. See Table 1.
