Our UPS supplier was quite happy to sell us the batteries that actually go in the MGE EXB units. I haven't actually tried it but if the batteries start going I will seriously consider this approach because it's considerably cheaper and I don't believe it will be too much hassle (and the EXB will be out of warranty anyway) > This also usually gives you more control over switchable outlets, in > case you want to remotely power-cycle one particular server. The Puslar Extreme we got (only 1500VA) had 6 outlets, 2 of which where individually switchable, I think if I wanted more control than that I would get a separate controllable outlet board. Personally I have *never* had to power cycle a server but I don't put Windows on then ;) The switchable outlets will come in handy for some of our other hardware though - occasionally the switch mode power supplies in our DAQ rack don't come up properly. -- Daniel O'Connor software and network engineer for Genesis Software - http://www.gsoft.com.au "The nice thing about standards is that there are so many of them to choose from." -- Andrew Tanenbaum GPG Fingerprint - 5596 B766 97C0 0E94 4347 295E E593 DC20 7B3F CE8C
