NOTE:
A minimum configuration must include one SPC and either one NPC
or one NP-IOC. However, if there are no NPCs in the chassis, the Ethernet
ports in the SFB will not be functional. See
“SRX3400 Services Gateway
Network Processing Cards” on page 20
,
“SRX3400 Services Gateway Services
Processing Cards” on page 20
for details about these cards.

Data Flow in the SRX3400 Services Gateway
The services gateway receives data from the various physical interfaces on the I/O cards
(IOCs). Incoming data is passed through the Switch Fabric Board (SFB) to a Network
Processing Card (NPC), back to the SFB and on to a Services Processing Card (SPC).
The data is then passed out of the services gateway in reverse order—to the SFB, NPC,
SFB, and out to the IOC.

SRX3400 Services Gateway Midplane
The midplane in the SRX3400 Services Gateway is in the center of the chassis and
provides connections for installing up to four common form-factor modules (CFMs)
through the front of the chassis and up to three CFMs through the rear of the chassis.
See
“Hardware Component Locations in the SRX3400 Services Gateway Chassis” on
page 11
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 services gateway power supplies are connected to the
midplane, which distributes power to all of the services gateway components.
