SRX5400 Services Gateway Chassis on page 7
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 services gateway 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.

Modular Port Concentrators (MPCs; see
two slots that accept Modular Interface Cards (MICs). These MICs add Ethernet ports
to your services gateway. You must install at least one MPC in the services gateway. You
can install MPCs into any of the slots
cannot install the MPC into the SCB slot (
NOTE: The SRX5400 Services Gateway does not support the I/O cards
(IOCs) or Flex IOCs supported by the SRX5600 and SRX5800 Services
Gateways. MPCs are the only supported interface cards for the SRX5400
Services Gateway.
If a slot in the card cage is not occupied by a card, you must install a blank panel to shield
the empty slot and to allow cooling air to circulate properly through the services gateway.
If a slot in an MPC is not occupied by a MIC, you must install a blank panel in the empty
MIC slot to shield it and to allow cooling air to circulate properly through the MPC.
