M120 cFPC Components

Both cFPC types consist of the following components:

• cFPC card carrier.
• 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.
• Crosspoint switches for redundancy.
• A metal bracket that enhances airflow and serves as a guide for removing and installing the cFPC.
• An LED located on the cFPC faceplate that displays the status of the cFPC.

The 10-Gigabit Ethernet cFPC also contains the following components:

• S2H FPGA—Bridge between HSL2 and one SPI-4.2 interface.
• 10-Gigabit Ethernet MAC interface circuitry.
• XFP optical transceiver (LAN/WAN PHY).

The OC192 cFPC also contains the following components:

• H2H FPGA—Bridge between HSLA and HSL1 interface.
• Juniper Networks D4P framer.
• XFP optical transceiver.
