SRX5400 Firewall Midplane Description

The midplane is located toward the rear of the chassis and forms the rear of the card cage. MPCs, SPCs,
and SCB 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 MPCs and SPCs through
the fabric ASICs on the SCB.
• Power distribution—The power supplies are connected to the midplane, which distributes power to
all the firewall components.
• Signal path—The midplane provides the signal path to the MPCs, SCB, SPCs, Routing Engine, and
other system components for monitoring and control of the system.
The enhanced midplane supports Junos OS Release 15.1X49-D10. It provides greater per-slot fabric
performance and signal integrity, along with error-free high speed data transfer, and it reduces cross-
talk. The midplane supports link speeds up to 10 Gbps and is not field replaceable.

SRX5400 Firewall Craft Interface Overview

The craft interface shows you status and troubleshooting information at a glance and lets you perform
many system control functions. It is hot-insertable and hot-removable. The craft interface is located on
the front of the firewall above the upper fan tray.
