Server power supply fault light glowing with alarm sounding. :Q
It's OK as there are three 300W modules and it can run even on 1 in a pinch so it's down to 2.
The nameplate for sake of familiarity:

Some inside pics:
wide angle shot
cute little fan and quite the powerhouse at the expense of some noise
Backside of the mainboard - lots of components onboard!
Big toroids!
More toroid action!
Iron core transformer
Heatsink mounted MOSFETs with another toroid
control board
caps beneath the power heatsinks
The culprit - BAD CAPS! :| Look at the domed tops.
This IS (or was) a good power supply module. But failures can/do/will happen hence the need for redundancy when availability is important. It's not a matter of if it will happen but when. This supply is about 3 years old and has been in use 24/7 right up to failure a few weeks ago. In our biz we use the term "ship happens". That's why we keep spares onhand.
