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.

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
Series Devices for more information about connecting and configuring redundant chassis clusters.
CAUTION:
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.
Description SPC with two SPUs of 256 GB memory.
