Message Action
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 38.
Power supply x 3.3 V fault (level-critical;
3.3 V power supply x had an error)
v
See “Power checkout” on page 38.
Power supply x 5 V fault (level-critical; 5 V
power supply x had an error)
v See “Power checkout” on page 38.
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.
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 116 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 38.
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.
System shutoff due to x V under voltage
(level-critical system shutoff due to x supply
under voltage)
1. Check the power-supply connectors.
2. Power supply.
3. Power cage assembly.
System shutoff due to VRM x over
voltage
v Replace VRM x .
System shutoff due to excessive (< 240
VA) loading
1. See “Power checkout” on page 38.
2. Cycle ac on/off.
