Number of
SRX5K-SCBsPlatform
This device supports one SCB for two fabric
planes, providing a redundancy of three SCBs.
If the active SCB fails, the device behavior
does not change as the remaining two SCBs
fulfill the requirement to have four fabric
planes.
If the second SCB also fails, no spare planes
are available in the chassis triggering
inter-chassis redundancy. Therefore, RG1+
will fail over to the secondary node.

NOTE: In SRX5600 and SRX5800 Services Gateways, failover does not happen when the
secondary Routing Engine in slot 1 fails, while the SCB in slot 1 is inactive.
