Right... but what about daisy chaining a small, cheap UPS off of the giant UPS at a data center? I was bitten by the recent outages (two in what, three days?) at he.net freemont 1. Word has it the outages lasted seconds, so even a really small UPS would have saved me. (of course, he.net charges by the circuit not by the KwH, so I'd have to leave enough headroom to run everything while charging the battery, which makes the proposition a little more expensive than I'd like.) Now, I'm wholly unqualified to speak about UPSs, as I've spent most of my career in data centers where that sort of thing is taken care of, but I've always been told to /never/ plug a UPS in to another UPS in a "Don't cross the streams" tone of voice. _______________________________________________ Tech mailing list [email protected] https://lists.lopsa.org/cgi-bin/mailman/listinfo/tech This list provided by the League of Professional System Administrators http://lopsa.org/
