    Checklist for Monitoring the HCM


    You monitor the High-Availability Chassis Manager (HCM) on the M10i router to ensure that it works with its companion Routing Engine to provide control and monitoring functions for router components. You also monitor the HCM to ensure that it displays alarm status and takes PICs online and offline. (See Table 1.)
