NOTE: Your services gateway cannot have a mix of SRX5K-SPC-2-10-40 SPCs and SRX5K-SPC3
SPCs. Starting with Junos OS release 18.2R2 and then 18.4R1 but not 18.3R1, you can have a
mix of SRX5K-SPC-4-15-320 SPCs and SRX5K-SPC3 SPCs.
Figure 36: Services Processing Card SRX5K-SPC3
Each SPC consists of the following components:
•
SPC cover, which functions as a ground plane and a stiffener.
•
Two 10–Gigabit Ethernet small form-factor pluggable plus (SFP+) chassis cluster control ports for
connecting multiple devices into a redundant chassis cluster. See the 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
•
One Gigabit Ethernet switch that provides control connectivity to the Routing Engine.
•
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 2.3-GHz CPU, system controller, and two 128 GB solid state-drives
(SSDs).
•
LEDs on the faceplate that indicate the SPC and SPU status.
