SRX5800 Services Gateway Component Redundancy

The following major hardware components are redundant:
Switch Control Boards (SCBs)—The SRX5800 Services Gateway has two SCBs installed and you can
install a third SCB for switch fabric redundancy. The SCB of the host subsystem functions as the master
and the others function as backup. If the SCB of the host subsystem fails, one of the other SCBs takes
over as the master.
Action
