Conﬁguring Uninterruptable Power Systems

After Conﬁguring the PowerTrust UPS

If adding any card or peripheral to a unit monitored by a UPS, you need

to recalculate the voltage/amperage (VA) draw.

Regardless of how many PowerTrust UPS devices are installed, only one

instance of the ups_mond daemon should be running at any time.

If you are running SupportWatch, you should include /usr/adm/syslog

among those ﬁles it monitors, in addition to /usr/bin/dmesg and

/usr/adm/diag.

A special circumstance should be noted for systems with external bus

extenders covered by a PowerTrust UPS. If for any reason, a disk in an

external bus extender loses power but the SPU to which it is conﬁgured

does not, you must wait the length of time for shutdown_timeout_mins

before cycling power to the SPU.

Troubleshooting the UPS

Error messages generated by the UPS are documented on the ups_mond

(1M) manpage.
