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.
