Checklist for Monitoring Redundant HCMs
Purpose 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 PICs
online and offline.
Table 161 on page 735 provides a checklist of tasks for you to perform to monitor redundant
HCMs.
