Q. Does Cisco Unified Communications Manager support APC UPS?<br>
A. From the Cisco Unified Communications Manager 6.0(1b) Release
Notes: Cisco Unified Communications Manager 6.0(1), when running on an
MCS 7825-H2 or MCS 7835-H2, supports basic integration to the following
UPS models: APC SmartUPS 1500VA USB and APC 750VA XL USB. Integration
is via a single point-to-point Universal Serial Bus (USB) connection.
Serial and SNMP connectivity to UPS not supported, and the USB
connection must be point-to-point (i.e. no USB hubs). Single and dual
USB UPS models are supported. The feature is normally activated
automatically upon bootup if connected to line power and a connected
UPS is detected. Alternatively, on MCS 7835-H2, running the CLI command
"show ups status" will activate the feature. On either supported server
model, the CLI command will also display detected hardware, detected
versions, current power draw, remaining battery runtime and other
relevant status information. Once the feature is activated, graceful
shutdown will commence upon detection of a low battery threshold.
Resumption or fluctuation of power will not interrupt or abort the
shutdown. For unsupported Cisco Unified Communications Manager
versions, MCS models and/or UPS vendor/make/models, the workaround
solution is to have an external script monitor the UPS, and when
appropriate conditions are detected, logon to Cisco Unified
Communications Manager via Secure Shell (SSH), access the CLI and run
the "utils system shutdown" command.<br>

It is not a very big UPS (3KVA) so i want to configure my servers to
normal shutdown when there is a power loss.<br>
APC support this for windows.<br>
What can i do with the Linux servers?<br>
<br>
Thanks<br>
