An UPS story

[The_Unbeliever]

Heyup

So we retired our two 2kVa UPS'es and installed three new 3kVa UPS'es in the server room

However, there is a slight problem.

USP monitoring.

How can I monitor three UPS'es, and send out shutdown signals when the battery's getting low?

On the previous two UPS'es we had, I used a hardware dongle, which plugged into the serial port of the UPS, and then you plug that dongle into the network. UPS monitoring is then done by an agent using SNMP. Should power go out, the servers monitoring said dongle will pick it up, and should battery get low, start a shutdown sequence.

Now I have tested this hardware dongle on the new UPS'es, and the serial protocol used by the new UPS'es is not supported.

Now my options is to either have one server (or a Windows workstation - also on UPS) monitor three UPS'es and send out a shutdown signal - or allow other servers to monitor this particular server/workstation for a shutdown signal and start it if there's a shutdown signal.

Which (free) software do you guys recommend to use in this scenario?

Thanks!

What make/model is the UPS's you bought? There must be monitoring software for them, even my ****ty OLD 600Va one had monitoring software and didn't require fancy cables and stuff in serial ports

RTFM?

It got sh*** software bundled. I don't like it as you need to install Flash. On a workstation it works fine.

And I don't want to be installing unnecessary add ons and stuff on a server.

The new UPSes comes with an network add on card that you install in one of the UPSes that can be used to manage the lot.
