T320 FPC Components and LEDs
Each FPC consists of the following components:
- FPC card carrier.
- One or two Packet Forwarding Engines. Each Type 1 FPC and Type 2 FPC has one Packet Forwarding Engine, and each Type 3 FPC has two Packet Forwarding Engines. Each Packet Forwarding Engines consists 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.
- 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. For more information on the FPC LEDs, see T320 Craft Interface FPC LEDs and Online/Offline Buttons.
- FPC online/offline button, located on the craft interface above the FPC.
