APC UPS Overload light blinking and constant alarm tone

APC UPS Overload light blinking and constant alarm tone

I have a Back-UPS XS 900 on a standalone Debian server that seems to randomly start sounding a constant overload alarm, even with nothing plugged in. The alarm continues to sound until I manually turn the unit off. Additionally, nothing seems to be logged when the alarm starts to sound.

"I had a MOSFET failure on my APC RS-1000 with the same observations as yours:
Overload light and constant alarm even when nothing was wired on the outputs.

They changed the board (rather the entire unit) and retained the batteries which were still functional.
Uh, I had some hard time working this out with the APC Service though. That was not exactly stellar."

"According to the manual if it happens every 5 hours, then the battery need change.

You don't describe what indicators light up though."

"It sounds to me like it is either dead / old battery or a general malfunction.

One thing about APC UPSs... Their price, you generally pay more, but they are generally brilliant quality and come with good support. You may want to email them and see what they say."
