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.
•
10GE 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.
