 |
|
The battery on my UPS just failed, and in doing so, it revealed three major problems with the unit:
1) When the battery self-test failed, everything connected to the "protected" outlets got power-cycled.
2) There's no way to mute the "battery failed" alarm, requiring me to deal with the problem at 4AM.
3) It's not possible to replace the battery without turning off the UPS.
Does anyone have a suggestion for a UPS suitable for running three ~100-watt computers for a few minutes that doesn't have the above flaws? The ability to signal Linux- or OpenBSD-based systems to shut down would be a nice bonus. |

Hi Carnildo,
The best is to start with the last question (or wish).

Take a look on this page

Then you can check out the diffrent types that support the first tree statements.
I run Powerware (Eaton) ups'es and many of them can hotswap the battery, and
you may silent the alarms from the front panel.
On battery fail it gives you an alarm that you have to change battery, but as long as
there is no critical error it would support the load from the main's.
But I think many of the more high end ups'es can do this. So start reading the list and
check out the manual for the ups'es and then you compare the price. |
