The midplane performs the following functions:
Transfer of packets—An incoming data packet crosses the midplane to a CFEB or
CFEB-E. The CFEB or CFEB-E performs switching and forwarding functions and transfers
outgoing packets back across the midplane to the FIC or PICs for transmission to the
network.
Power distribution—The midplane distributes power to all router components from
the power supplies attached to it.
Signal connectivity—The midplane transports the signals exchanged by system
components for monitoring and control purposes.

The cable management system consists of racks that attach vertically to each side of
the chassis at the front. Pass PIC cables through the slots in the racks to keep the cables
organized and securely in place, and to avoid bending optical cables beyond the proper
bend radius. The cable management system evenly distributes the weight of a cable, so
that it is not subjected to undue stress at the connector.
