Typical - you're overloading the circuit.

EEEK - you don't have your laser printer on the UPS, do you?

Systems should be on UPS, not the printer - if the printer causes a brown-out, the UPS should save the systems, unless the UPS on the systems is shot (have you tested it?)...

Yes - another power circuit. I plan to run two to my "server room" - one for each rack, with 1500 - 2200 VA UPS on each for the systems, and some smaller UPS for network elements (cable, router, WAP, FTP appliance[0], etc.)


[0] I dug up my old CompUSA "LANDISK" network drive chassis - it puts a single IDE drive on the network as an SMB and/or FTP server - I plan to use it as an anonymous FTP server for my home network, allowing me to drop stuff off/make it available with limited exposure to my other equipment. I got it several years ago at half-price (open box), before CompUSA became Tiger Direct. Link: http://fmi.compusa.com/attach/b03333de-2776-4d1d-abc6-29374c1b31fc.doc (sorry, MS-Word format)

I also started playing with my Netgear SC101 Storage Central device - it's speed isn't that bad, and once Iloaded the drivers, it appeared on my Windows Server 2003 machine as a shared network drive. I don't have matched drives inside it, but I think I will do so, and make it a RAID 1 storage device for misc files I don't want to loose, and would like to share across multiple machines easily.
