Power error messages
Note: See “System replaceable units” on page 131 to determine which components should be replaced by a field
service technician.
Message Action
Power supply x current share fault
(level-critical; excessive current demand on
power supply x)
v
Replace power supply x .
Power supply x DC good fault
(level-critical; power good signal not detected
for power supply x )
v
Replace power supply x .
Power supply x temperature fault
v Replace power supply x .
Power supply x removed
v
No action required – information only.
Power supply x fan fault (level-critical; fan
fault in power supply x )
v Replace power supply x .
Power supply x 12 V fault (level-critical;
overcurrent condition detected)
v
See “Power checkout” on page 21.
Power supply x 3.3 V fault (level-critical;
3.3 V power supply x had an error)
v See “Power checkout” on page 21.
Power supply x 5 V fault (level-critical; 5 V
power supply x had an error)
v See “Power checkout” on page 21.
System running non-redundant power
(level-noncritical; system does not have
redundant power)
1. Add another power supply.
2. Remove options from system.
3. System can continue to operate without redundancy protection if
steps1 and 2 are not followed.
System under recommended voltage for x
(level-warning; indicated voltage supply
under nominal value; value for x can be +12,
-12, or +5)
1. Check connections to the power subsystem.
2. Power supply.
3. Power cage assembly, if installed.
System shutdown
See the following tables when experiencing system shutdown related to voltage or
temperature problems.
Voltage-related system shutdown
Note: See “System replaceable units” on page 131 to determine which components should be replaced by a field
service technician.
Message Action
System shutoff due to x current over
max value (level-critical; system drawing
too much current on voltage x bus)
v
See “Power checkout” on page 21.
System shutoff due to x V over voltage
(level-critical; system shutoff due to x
supply over voltage)
1. Check the power-supply connectors.
2. Power supply.
3. Power cage assembly, if installed.
