This is about a Tripp-Lite UPS model SU100RTXL2UA Series AGPS5180 UPS.
Some time in the past, without thinking about it I connected a new Tripplite UPS to an older external battery pack. It 'disabled' the new UPS instantly, and it would not turn on again until Tripplite support gave me an unlock code which required a certain series of button pushing and stuff... Unfortunately at the time I never wrote the steps down. Fast forward to today, I have the exact same problem. The external extended battery pack seems to have failed (10v where it should be 24v). It seems to have done the same thing to the UPS. Symptoms are as follows:
- Line and Load LEDs are lit, Online is not. All three should light up when the device is running.
- On and Off buttons do nothing except when held down, and then only cause the unit to beep once and then no change
- The internal batteries on this device give 13volts, so they appear to be in working order
I expect a hard reset like the one before is all that is necessary resolve the issue, but the device is out of warranty, and I don't expect help from support for it. Any suggestions are welcomed!
