Chapter 3 Managing and Monitoring the Health of Cisco Unified Communications Manager Systems General Health and Troubleshooting Tips Integration with Uninterruptible Power Supplies (UPS) As of Cisco Unified CM Release 6.0(1a) and later, the server supports integration with certain models of APC UPS for certain MCS 7800 models. Previous server releases rely on an external script monitoring the UPS and issuing the Cisco CLI for graceful shutdown. See the release notes for Cisco Unified CM 6.0(1b) for more details at http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/rel_notes/6_0_1/cucm-rel_note-601b.html. Note Native hardware out-of-band management such as HP iLO or IBM RSA II cannot be used for graceful shutdown of Cisco Unified CM. Native Hardware Out of Band Management (OOB) The supported features of HP iLO and IBM RSA II are enabled for the following areas: • CPU status/utilization • Memory status/utilization • System components temperatures • Fan status • Power Supply status • RAID & disk status • Network status including NIC • Operational status, including instrumentation of system/kernel status and data dumps following major system issues, indicating nature/type of the operational problem and degree of severity. Support of these interfaces on the server includes the following capabilities (specific feature names vary by hardware vendor): • Remote console (to access boot screens and the Cisco CLI) • Remote power management Phone Registration Status Phone registration status needs to be monitored for sudden changes. If the registration status changes slightly and readjusts quickly over a short time frame, then it could be indicative of phone move, add, or change. A sudden smaller drop in phone registration counter can be indicative of a localized outage, for instance an access switch or a WAN circuit outage or malfunction. A significant drop in registered phone level needs immediate attention by the administrator. This counter especially needs to be monitored before and after the upgrades to ensure the system is restored completely.
