The host subsystem provides the routing and system management functions of the
router. You can install one or two host subsystems on the router. To operate, each host
subsystem functions as a unit; the Routing Engine requires the corresponding control
board, and vice versa.
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
RE0
Each host subsystem has three LEDs that display its status. The host subsystem LEDs
are located on the upper right of the craft interface. For more information about the host
subsystem LEDs, see "T640 Craft Interface Host Subsystem LEDs" on page
