You monitor redundant High-Availability Chassis Managers (HCMs) on the M10i
router so they can work with a companion Routing Engine to provide control and
monitoring functions for router components. The HCMs also display alarm status
and take Physical Interface Cards (PICs) online and offline.
Table 131 provides a checklist of tasks for you to perform to monitor redundant
HCMs.
