MX240 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.
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.
