Re: [CGUYS] UPS Question
The more sophisticated units often have self-test circuitry even if the unit is setup to be monitored by a connected computer; this may relate to the 2-4 AM thing. The other issue might be a failing battery. They do wear out. I have 2 TrippLite 1000VA units that have a real time read-out for the line voltage. They were about $100 the last time I saw one at Costco. YMMV I know UPS issues have been covered in the past. As many of you may know, I'm an advocate of using them. Recently (within the past 2 weeks!) we have begun having UPS issues: To wit: Sometimes, in the middle of the night (2 am - 4 am), two of our UPS's begin to click / beep. Not sound an alarm, mind you, just to click / beep quietly in a rhythmic pattern. I cannot find reference to what this might mean, though I think it means that the circuit being used is browning out power and the UPS is making up the missing power. Last night this happened at about 11 pm!!! Eventually, the UPS's (we have many, but only two are involved in this situation) begin to blare. Then everything shuts down and they continue to blare until reset and recharged. This is a very frustrating situation as it only affects two of our 4 UPS units (all in the same room, but possibly on separate circuits). It is also happening to a neighbor! Same scenario. Only our UPS's are far enough away that they don't wake us. Hers, sadly, wakes her when it begins to scream. (Please don't ask about the 2 am - 4 am thing. I sometimes work late into the night/morning.) We can tell when this scenario has occurred because a telephone answering machine ceases to work, and because my iMac is turned off. There are two UPS units involved. One has only the telephone answering machine plugged into its battery back-up sockets, and the other has only my iMac connected to its battery back-up sockets. Dedicated UPS's if you will. It is unclear if these are on the same circuit breaker or not. It's also weird that sometimes one of the UPS's is affected, and sometimes both of them are affected at the same time. I have searched for references to sounds made by APC UPS units without success. These units are all relatively new (a higher capacity one was purchased last week for my computer in the hope that would help resolve the problem with my computer shutting down, but to no avail), and their batteries should be in good condition. Any help / advice / would be appreciated. -- I may not have gone where I intended to go, but I think I have ended up where I needed to be. - Douglas Adams * == QUICK LIST-COMMAND REFERENCE - Put the following commands in == * == the body of an email send 'em to: [EMAIL PROTECTED] == * Join the list: SUBSCRIBE COMPUTERGUYS-L Your Name * Too much mail?

Re: [CGUYS] UPS Question
A UPS will also get unstable and noisy if the voltage goes up. appliances and electronics will be unhappy also. get a line meter from radio shack(i am not a part of radio shack). If the meter is bouncing up, and up a lot, call the power company, and tell they you have lost your neutral. very big, and very dangerous problem. keep punching buttons at power company till you get a human. they should have people out within a couple of hours. the way AC works is it is pushed on one wire and pulled on the other. each run between +/-110 and ground. if the neutral goes, that is one of the two wires, and the circuit is run between one of the power wires, and the ground(water pipe) it is not a great conductor, so the +110 push can get up to 2-300 volts. it kills electrics, and it kills people. yes, we lost ours. I got through at 7pm. pepco showed up at 9 pm with a crew of 6-10, 2 backhoes, etc.etc. they stayed for 3 days, destroyed the front lawn and driveway. they pay for all killed equipment. Any help / advice / would be appreciated.
