used an APC with excellent results. The biggest issue we had was where the
UPS had a serial line instead of a USB. Never did figure that out, other
things got in the way, and the company folded before I got a chance
to. But the USB version of the UPS worked great. The key was apcupsd
( <a href="http://www.apcupsd.org/" target="_blank" onclick="return top.js.OpenExtLink(window,event,this)">http://www.apcupsd.org/</a> ) - a
daemon which took care of it all. Did a nice job of seeing the power
failure, waiting until there was so much time left, and then shutting
down. We had multiple servers on each UPS, one of the nice features
of apcupsd was it's ability to talk to it's master - the server which was
actually talking to the UPS. So all servers would shut down
cleanly.</font></span></div>

<div><span><font color="#0000ff" face="Arial" size="2">What
was hilarious was the day we were testing and got the first server and slave
(client) running properly was the day the power went out. The two boxes we
were testing with behaved beautifully, everything else had to be shut down
manually.</font></span></div>
<div><span><font color="#0000ff" face="Arial" size="2"></font></span> </div>
<div><span><font color="#0000ff" face="Arial" size="2">We
also had a bunch of Belkins, the IT guy filled those up, not noticing that there
were 3 surge protected ports and three battery backed up ports. Guess
which ports he plugged the servers into and which ones he plugged the monitors
into... ;-). I was not as happy with those.</font></span></div>
<div><span><font color="#0000ff" face="Arial" size="2"></font></span> </div>
<div><span><font color="#0000ff" face="Arial" size="2">Always
a good idea to have a monitor plugged into the UPS as well. Especially one
which can get to all of the boxes nearby, just in case.</font></span></div>
<div><span><font color="#0000ff" face="Arial" size="2"></font></span> </div>
<div><span><font color="#0000ff" face="Arial" size="2">With
all UPS's you need to be aware of battery life - after two years (or so) you
want to replace the battery.</font></span></div>
<div><span><font color="#0000ff" face="Arial" size="2"></font></span> </div>
<div><span><font color="#0000ff" face="Arial" size="2">Be wary of the advertised 'uptime' of any UPS and what actually
happens. They may offer 15 minutes, but with 2-3 servers plugged into it,
that turns into 90 seconds real fast. You will want to test how long you
actually get and adjust the apcupsd settings accordingly. We saw servers
shutdown within the first 5 minutes generally - but then that's why you have
this thing - so you get a clean shutdown.</font></span></div></div><div><span class="sg">

know of a good affordable linux compatible ups?<br><br></font></div>Hi, I am
looking for a linux compatible UPS...basically one that will in the presence of
loss power, will be able to let the server shutdown cleanly...the server has 3
power supplies, each at 550 watts so I think it constantly uses a total of 1650
watts (it's a HP NetServer LH3R)...would like a affordable yet reliable
UPS...anyone got any recommendations? Thanks! :-) <br></span></div><div></div>
