[H-GEN] U.P.S

Hi,

Does your UPS have a serial cable connection?  The idea is that once the UPS
battries run low, a signal is sent to the computer to tell it to shut down
cleanly.  This is what the software is for, to listen for this signal and
run the appropriate shutdown command.

Regards,

Jason

G'day,
I was given an  APC UPS with 4 outlet sockets, some eight months ago. I
think it is quite old, but works fine with all the small outages we seem to
get in the Corinda area.

A test with just one boxen attached [no monitor] showed that the E Smith
router/firewall would run for +/- 10 minutes, after the UPS was unplugged
from the wall. I guess that a pair of new batteries would see it run for a
little/lot longer. But I don't know what the 'norm' is for these things.

It is the model with 2 x 12 volt sealed batteries, in series. The footprint
is about the same as an AT boxen [but a good deal heavier!!!].

My question is
What software is needed by Linux? I thought this thing was just hardware. A
sort of 'Plug in 'n leave alone'. cheers Tony
