From folks I've talked to (engineers and industry people), Powerware seems to be known as the UPS that just works. I've yet to talk to one person who had a powerware die on them. Myself included.
We are a Powerware house. We had a large number of 3kVA and 6kVA units in our previous data centre (no-one would stump up the cash for a large unit so we had to buy them as we needed them). After about 5 years (very rough figure), we've now had 3 or 4 units fail, sometimes in the UPS, sometimes in the bypass unit. They all seem to be component failures (in the case of the bypass unit, a leg broke off a small capacitor). I don't think we've replaced any of the batteries in that time and they're still all holding charge well, even at full load.
Perhaps I should have been clear. In my entire post, sed s/powerware/powerware 9315/g
At our new site we have some 50kVA and 80kVA units that we inherited from the previous owners. One is already exhibiting the signs of a failing fan, but we have no idea what their history is before we moved in.
Well, fans would fall under maintenance, no? Perhaps, also, someone is not changing filters, or whatnot. -- Alex Rubenstein, AR97, K2AHR, alex@nac.net, latency, Al Reuben -- -- Net Access Corporation, 800-NET-ME-36, http://www.nac.net --
