[QUOTE="bassman, post: 27421, member: 1514"] Confusing If the computers are powered via the UPS surely they carry on when power is turned of.I have sites that are tested monthly for this reason to make sure that the UPS keeps the computers running. Only the computers no screens or printers. Depends on what type of UPS as the newer models APC type have audible to let some one know that they have gone to inverter. If it is only small units usually fed via kettle lead unplug lead before doing maintenance and wait till power restored before plugging back in.They are suppressed for transients, but not woth the risk.There is also a lead to put between PC and UPS which you can program for pc to shutdown and save any info, very rarely used.
