Table 10. Power error messages (continued)
Message Action
Power supply X fan fault (level-critical; fan
fault in power supply X )
1. Replace power supply X
Power supply X 12-V fault (level-critical;
overcurrent condition detected)
1. See “Power problems” on page 91
Power supply X 3.3-V fault (level-critical;
3.3-V power supply X had an error)
1. See “Power problems” on page 91
Power supply X 5-V fault (level-critical; 5-V
power supply X had an error)
1. See “Power problems” on page 91
System over recommended X current
(level-non-critical; system running too much
current on that voltage)
1. See “Power problems” on page 91
System running non-redundant power
(level-non-critical; 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 1
and 2 above are not followed.
System under recommended voltage for
X v (level-warning; indicated voltage supply
under nominal value; value for X can be +12,
-12, or +5)
1. Check connections to power subsystem
2. Replace power supply
3. Replace power backplane
System under recommended voltage on
3.3-V
(level-warning; 3.3-volt supply under
nominal value)
1. Check connections to power subsystem
2. Replace power supply
3. Replace power backplane
System under recommended X current
(level-non-critical; system drawing less
current than recommended on voltage
X )
1. See “Power problems” on page 91
X V bus fault (level-critical; overcurrent
condition on X voltage bus)
1. Check for short circuit on X voltage bus
2. See “Power problems” on page 91
12-V X bus fault (level-critical; overcurrent
condition on 12-volt X voltage bus)
1. Check for short circuit on 12-volt X voltage bus
2. See “Power problems” on page 91
5-V fault (level-critical; overcurrent condition
on 5-V subsystem)
1. Check for short circuit on 5-V bus
2. See “Power problems” on page 91
240 VA fault (level-critical; overcurrent or
overvoltage condition in power subsystem)
1. See “Power problems” on page 91
Recovering BIOS
If your BIOS has become corrupted, such as from a power failure during a flash
update, you can recover your BIOS using the recovery boot block and a BIOS flash
diskette.
Note: You can obtain a BIOS flash diskette image in one of the following ways:
v
Download a BIOS flash diskette from the Web site at:
www.ibm.com/storage/support/nas
v
Contact your IBM service representative.
The flash memory contains a protected area that cannot be overwritten. The
recovery boot block is a section of code in this protected area that enables the
