Routing Engine Component Companionship
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 “Checklist for Monitoring the HCM” on page 531.
For more information about monitoring Redundant HCMs, see “Checklist for Monitoring
Redundant HCMs” on page 735.
For information about monitoring redundant Routing Engines, see “Checklist for Monitoring
Redundant Routing Engines” on page 591.
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 435. For more information about
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 367. For information about the
Control Boards, see “Checklist for Monitoring the Control Board” on page 381.
For more detailed information about the Routing Engine, see the appropriate router
