MX960 Host Subsystem Description
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.
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
Each host subsystem has three LEDs that display its status. The host subsystem LEDs are located in the middle of the craft interface.
