The host subsystem provides the routing and system management functions of the
router. You can install one or two host subsystems on the router. Each host subsystem
functions as a unit; the Routing Engine must be installed directly into the Switch Control
Board.
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 three LEDs that display its status. The host subsystem LEDs
are located in the middle of the craft interface.
