SRX3600 Services Gateway Midplane
The midplane in the SRX3600 Services Gateway is in the center of the chassis and provides connections for installing up to six common form-factor modules (CFMs) through the front of the chassis and up to six CFMs through the rear of the chassis. Refer to Hardware Component Locations in the SRX3600 Services Gateway Chassis for details about where the individual modules can be installed. 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 SFBs.
- Power distribution—The device power supplies are connected to the midplane, which distributes power to all of the device components.
- Signal path—The midplane provides the signal path to the IOCs, SFBs, SPCs, Routing Engine, and other device components for monitoring and control of the system.
