UPS & auto shutdown

By SysAdmin1138 on
It seems that the Liebert UPS in our datacenter has a network card in it. This is a surprise to me. I was hunting for the fabled RS-232 connection to which I get to connect a UPS cable, and found this device. There it was, with the following info on it:
  • Text that read PWA, SNMP/MODEM
  • A DB-9 male connector
  • An RJ-23 connector
  • An RJ-45 connector
  • A sticker with a MAC address on it
To me that looks like a network card. If this is indeed a network card, then we may not need a server to act as the interface between the UPS and the server shutdown agents. Nice, as we don't have anything to really use in that sort of mission critical, but almost never really used, capacity.

The trick will be figuring out exactly what this card is, and how to use it. The Liebert site is useless, as this model is not referenced anywhere. Our model of UPS isn't up there anymore, though Google can find links to its manuals. This particular card doesn't look like the newer SNMP-management card. The manual says that one does exist for this model of UPS, but we are to reference the separate manual for configuration details.

Wheeeeee.
