    Host Subsystem in an EX9208 Switch

    Switching and routing functionality, system management, and system control functions of an EX9208 switch are performed by host subsystem. A host subsystem consists of a Routing Engine functioning together with a Switch Fabric.

    You can install either one or two host subsystems in the slots labeled 0 and 1 in the front panel of the chassis. A base configuration EX9208 switch has one host subsystem. A redundant configuration EX9208 switch has a second host subsystem.

    Note: We recommend that you install two host subsystems for redundant protection. If you install only one host subsystem, we recommend that you install it in slot 0.

    Each host subsystem has LEDs in the craft interface that display its status. See Craft Interface in an EX9208 Switch
