Power error messages

Note: See "System" on page 112 to determine which components should be replaced by a field service technician.
Message
Power supply x current share fault
(level-critical; excessive current demand on
power supply x)
Power supply x DC good fault
(level-critical; power good signal not detected
for power supply x)
Power supply x temperature fault
Power supply x removed
Power supply x fan fault (level-critical; fan
fault in power supply x)
Power supply x 12 V fault (level-critical;
overcurrent condition detected)
Power supply x 3.3 V fault (level-critical;
3.3 V power supply x had an error)
Power supply x 5 V fault (level-critical; 5 V
power supply x had an error)
System running non-redundant power
(level-noncritical; system does not have
redundant power)
System under recommended voltage for x
(level-warning; indicated voltage supply
under nominal value; value for x can be +12,
-12, or +5)

System shutdown

Refer to the following tables when experiencing system shutdown related to voltage
or temperature problems.

Voltage related system shutdown

Note: See "System" on page 112 to determine which components should be replaced by a field service technician.
Message
System shutoff due to x current over
max value (level-critical; system drawing
too much current on voltage x bus)
System shutoff due to x V over voltage
(level-critical; system shutoff due to x
supply over voltage)
System shutoff due to x V under voltage
(level-critical; system shutoff due to x
supply under voltage)
Action
