On the M10i router, the Routing Engine works with its companion High-Availability Chassis
Manager (HCM) to provide control and monitoring functions for router components. For
more information about the HCM, see

On the M40e and M160 routers, the host module provides the routing and system
management functions. The host module consists of the Routing Engine and the
Miscellaneous Control Subsystem (MCS). For more information about the host module,
see "Checklist for Monitoring the Host Module" on page
the MCS, see "Checklist for Monitoring the MCS" on page 455
On the M320 router, T320 router, and T640 router, the host subsystem provides the
routing and system management functions. The host subsystem consists of the Routing
Engine and the Control Board. For more information about the host subsystem, see
"Checklist for Monitoring the Host Subsystem" on page
Control Boards, see "Checklist for Monitoring the Control Board" on page
For more detailed information about the Routing Engine, see the appropriate router
