Server User Manual
Enter the Name of the particular remote UPS that you want to remotely monitor. This name
must be the name that the remote UPS was configured with on the remote console server
(because the remote console server may itself have multiple UPSes attached that it manages
locally with NUT). Optionally, enter a Description.
Enter the IP Address or DNS name of the remote console server* that is managing the remote
UPS. (*This may be another Black Box console server or it may be a generic Linux server running
Network UPS Tools.)
Note An example where centrally monitor remotely distributed UPSes is useful is a campus or large
business site where there’s a multitude of computer and other equipment sites spread afar, each
with their own UPS supply … and many of these (particularly the smaller sites) will be USB or
serially connected.
Having a console server at these remote sites would enable the system manager to centrally
monitor the status of the power supplies at all sites, and centralize alarms. So he/she can be
warned to initiate a call-out or shut-down.
Check Log Status and specify the Log Rate (minutes between samples) if you want the status
from this UPS to be logged. You can view these logs from the Status: UPS Status screen.
Check Enable Shutdown Script if this remote UPS is the UPS providing power to the console
server itself. If the UPS reaches critical battery status, the custom script in
/etc/config/scripts/ups-shutdown runs, enabling you to perform any
“last gasp” actions.
Click Apply.
8.2.3 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 shut down gracefully if you have UPS problems.
For Linux computers, set up upsmon on each computer and direct them to monitor the console server
that is managing their UPS. This will set the specific conditions that will be used to initiate a power down
of the computer. Non-critical servers may be powered down some seconds after the UPS starts running
