also connect to the midplane.
The midplane performs the following major functions:
Data path—Data packets are transferred across the midplane from the Packet
Forwarding Engine on the originating FPC to the SIBs, and from the SIBs across the
midplane to the Packet Forwarding Engine on the destination FPC.
Power distribution—The router power supplies are connected to the midplane, which
distributes power to all the router components.
Signal path—The midplane provides the signal path to the FPCs, SIBs, Routing Engines,
CB, and other system components for monitoring and control of the system.
