[cisco-voip] Graceful Shutdown CUCM7.x

[Jack Martin]

Has anyone out there in Voipland implemented this solution and has it proven to be all that it claims to be?

Uninterruptible Power Supply
Cisco recommends that you connect each Cisco Unified Communications Manager server to an uninterruptible power supply (UPS) to provide backup power and protect your system against a power failure.

Note You must connect MCS-7816 and MCS-7825 servers to a UPS to prevent file system corruption during power outages.
________________________________
When Cisco Unified Communications Manager runs on one of the servers that are listed in Table 2<http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/rel_notes/7_1_3/cucm-rel_notes-713.html#wp1790061>, basic integration to the UPS model APC SmartUPS 1500VA USB and APC 750VA XL USB gets supported.
Integration occurs via a single point-to-point Universal Serial Bus (USB) connection. Serial and SNMP connectivity to UPS does not get supported, and the USB connection must be point-to-point (in other words, no USB hubs). Single- and dual-USB UPS models get supported with the APC SmartUPS 1500VA USB and APC 750VA XL USB. The feature activates automatically during bootup if a connected UPS gets detected.
Alternatively, you can execute the CLI command show ups status that shows the current status of the USB-connected APC smart-UPS device and starts the monitoring service if it is not already started. The CLI command also displays detected hardware, detected versions, current power draw, remaining battery runtime, and other relevant status information.
When the feature is activated, graceful shutdown will commence as soon as the low battery threshold is reached. Resumption or fluctuation of power will not interrupt or abort the shutdown, and administrators cannot stop the shutdown after the feature is activated.
For unsupported Cisco Unified Communications Manager releases, MCS models and/or UPS vendor/make/models, you can cause an external script to monitor the UPS. When low battery gets detected, you can log on to Cisco Unified Communications Manager by using Secure Shell (SSH), access the CLI, and execute the utils system shutdown command.

Subject: Graceful Shutdown CUCM7.x

Does Cisco or a third-party have a solution to perform a graceful shutdown of a CUCM 7.x appliance?  We have a customer that experiences periodic power failures.  They are running PowerChute, which has an agent for Linux.  Is this software supported on the appliance?  I know us plebes don't have root access, but could I open a TAC case to have the PowerChute agent installed, assuming that it is supported?
