It's the RAID controller card.

That really sounds like a UPS. Do you have diagnostics access
for it?


Sounds to me like a UPS buck-boost in action.  What is your UPS unit?

Alternatively: do you have machines with redundant power
supplies? You may have just burnt one out. (Or it needs to be
reset.)

Just a little story...

Beeps and other tones of a kilohertz or so within a room with hard walls
are most amazingly non-directional, and can be remarkably hard to
locate. I spent a couple of hours over several days trying to work out
why my server seemed to have acquired an alarm set for midnight. I
eventually found that I had picked up my radio clock/weather station
and had inadvertently pushed a button which enabled an alarm which
defaulted to midnight, which I didn't know the thing could even do...

Find the model number of the computer (guessing it's a rack-mounted server
of some kind) and find its manual and see if it has diagnostic beep codes.
