Figure 4: Services Processing Card SRX5K-SPC-4-15-320
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. See Chassis Cluster User Guide for SRX Series Devices for more information
about connecting and configuring redundant chassis clusters.
CAUTION: If you face a problem running a Juniper Networks device that uses a
third-party optic or cable, the Juniper Networks Technical Assistance Center (JTAC)
can help you diagnose the source of the problem. Your JTAC engineer might
recommend that you check the third-party optic or cable and potentially replace
it with an equivalent Juniper Networks optic or cable that is qualified for the device.
•
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.
