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 OS Security Configuration Guide for more information about connecting and configuring redundant chassis clusters.

  Note: We strongly recommend the use of Juniper Networks SFP transceivers. We cannot guarantee correct operation if other 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 that indicate the SPC status.
