Replaced 655A Power Unit in slot 24A15. It solved the problem, and the alarm cleared:

Note: if replacement of 655A power supply does not resolve the error ---- the IPSI (TN2312BP) could be the issue.
The POW-SUP maintenance object notes the presence of each power supply and the voltage of each power supply in the G650.
This MO:
● Verifies that a power supply that is administered is physically present
● Verifies that each output voltage (+5V, -5V, and -48V for the power supplies and +12V for
the fan) is within tolerance
● Is used with the recycle carrier command to momentarily turn off and on the power to
a specified power supply or to a specified carrier
● Is used to turn off output voltages from one power supply to verify that the other supply can
support the entire load of the G650 (This is used only when a G650 has redundant power
supplies.)
