7.2.3 Controlling UPS powered computers
One of the advantages of having a Managed UPS is that you can configure computers that draw power
through that UPS to be shut down gracefully in the event of UPS problems.
For Linux computers this can be done by setting up upsmon on each computer and directing them to
monitor the console server that is managing their UPS. This will set the conditions that will be used to
initiate a power down of the computer. Non-critical servers may be powered down some second after the
UPS starts running on battery, whereas more critical servers may not be shut down until a low battery
warning is received.
An example upsmon.conf entry might look like:
MONITOR managedups@192.168.0.1 1 username password slave
• managedups is the UPS Name of the Managed UPS
• 192.168.0.1 is the IP address of the Opengear console server
• 1 indicates the server has a single power supply attached to this UPS
• username is the Username of the Managed UPS
• password is the Password of the Manager UPS
There are NUT monitoring clients available for Windows computers (WinNUT).
If you have an RPC (PDU) it is also possible to shut down UPS powered computers and other equipment
without them having a client running (e.g. communications and surveillance gear). Set up a UPS alert and
using this to trigger a script which control a PDU to shut off the power.
