M120 FPC Components

Each FPC consists of the following components:

• FPC card carrier, which includes the PIC slots.
• HSL2 conversion FPGA, a bridge between the HSL2 interface and the interface required by the types of supported PICs (either BD8, BD32 or HSL1).
• HSL2 crossbar connection to the FEBs.
• PIC CPU complex.
• Physical PIC connectors.
• Midplane connectors and power circuitry.
• Processor subsystem, which includes a 667-MHz CPU, system controller, 128 MB of SDRAM, and two Fast Ethernet links to the Control Board.
• An LED, located on the craft interface above the FPC, that displays the status of the FPC.
• FPC online/offline button, located on the craft interface above the FPC.
