SRX5800 Services Gateway Midplane Description

The midplane is located toward the rear of the chassis and forms the rear of the card cage (see
Figure 4 on page 35). IOCs, SPCs, and SCBs install into the midplane from the front of the chassis, and the
power supplies install into the midplane from the rear of the chassis. The cooling system components also
connect to the midplane.
The midplane performs the following major functions:
Data path—Data packets are transferred across the midplane between the IOCs and SPCs through the
fabric ASICs on the SCBs.
Power distribution—The power supplies are connected to the midplane, which distributes power to all
the services gateway components.
Signal path—The midplane provides the signal path to the IOCs, SCBs, SPCs, Routing Engine, and other
system components for monitoring and control of the system.
