The cable it turns out during some testing is to do with the mode of the
UPS.
A "smart serial UPS" needs a different cable than a "dumb serial" UPS.
We had a APC Smart UPS 1000 and the cable that came with it (Dark grey)
would make a signal appear with powestatd even if the other end wasn't
plugged into anything - that is - just a loose cable plugged into the serial
port of the server.
I have used a dumb APC model (Back UPS Pro SI) with powerstatd and Graeme's
howto and had no problems at all - apart from getting the init string
correct.
To use powerstad with a smart UPS - you will need to plug the UPS into a
machine running APC's Power chute (Windows or Linux) and set the system to
"dumb" mode. This saves it into the nvram of the UPS. Then you can hook
the UPS up to a server with powerstatd and a dumb serial cable (Light grey)
and all should work. Note that last step - I am about to test this week -
it should work given all the info I could get from APC on the phone.
Cheers,
Richard.
