SRX5600 Services Gateway Services Processing Card Components
Each SPC consists of the following components:
- SPC cover, which functions as a ground plane and a stiffener.
- Two Small Form-factor Pluggable (SFP) Chassis Cluster
Control ports for connecting multiple devices into a redundant chassis
cluster. Refer to the JUNOS Software Security Configuration Guide for more information
about connecting and configuring redundant chassis clusters.

Note: Juniper strongly recommends the use of Juniper SFP transceivers. Juniper cannot guarantee correct operation if non-Juniper transceivers are used. The transceiver type can be different in each port, as long as a supported part number is used.
- Fabric interfaces.
- Two Gigabit Ethernet interfaces that allow control information, route information, and statistics to be sent between the Routing Engine and the CPU on the SPCs.
- Two interfaces from the SCBs that enable the boards to be powered on and controlled.
- Physical SPC connectors.
- Midplane connectors and power circuitry.
- Processor subsystem, which includes a 1.2-GHz CPU, system controller, and 1 GB of SDRAM.
- LEDs on the faceplate indicate the SPC status (see ).
