Midplane

The midplane is a panel located in the center of the chassis, running from side to
side and forming the rear of the PIC card cage (see
plug directly into the midplane. The midplane contains an EEPROM that stores the
serial number and revision level of the midplane.
The midplane performs the following functions:

Value
8.7 in. (22.1 cm)
17.5 in. (44.5 cm) for sides of chassis
19 in. (48.3 cm) with mounting brackets
18 in. (45.7 cm)
79 lb (35.8 kg)
57 lb (25.9 kg)
AC: 3276 BTU/hour (960 W)
DC: 1965 BTU/hour (576 W)
Transfer of packets—After being processed by a PIC, an incoming data packet
crosses the midplane to the CFEB. The CFEB performs switching and forwarding
functions and transfers outgoing packets back across the midplane to the PICs
for transmission to the network.
Power distribution—The midplane distributes power to all router components
from the power supplies attached to it. It also provides hot-plug protection for
the PIC and HCM slots.
Signal connectivity—The midplane transports the signals exchanged by system
components for monitoring and control purposes.
