Power is not within normal
operating parameters. If this alert appears on multiple
power supplies, ensure that all of the
power supplies are properly installed.
If only one power supply appears
with this alert, replace it.
ON
There is an over-temp condition in
the power supply. This can occur
either because a power supply has
been removed, resulting in lower
total power; improper cabinet
cooling due to exhaust air
obstructions, or because an
individual power supply is faulty. Check the fans and make sure all the
access panels are in place. Verify the
cabinet cooling exhaust air is
unobstructed and is being properly
vented away from the cabinet.
Verify filter media is clean and
unobstructed.
If the fans are working, the panels are
in place, no obstructions to the
exhaust air, and the Temp LED is
still on, then replace the power
supply.
