Power error messages
Message Action
Power supply "X" current fault (level-critical;
excessive current demand on power supply
"X")
1. See “Power checkout” on page 32.
Power supply "X" DC good fault (level-
critical; power good signal not detected for
power supply "X")
1. Replace power supply "X"
Power supply "X" fan fault (level-critical; fan
fault in power supply "X")
1. Replace power supply "X"
Power supply "X" fault (level-critical;
overcurrent condition exists)
1. See “Power checkout” on page 32.
Power supply "X" 12V fault (level-critical;
overcurrent condition detected)
1. See “Power checkout” on page 32.
Power supply "X" 3.3V fault
(level-critical; 3.3V power supply "X" had an
error)
1. See “Power checkout” on page 32.
Power supply "X" 5V fault (level-critical; 5V
power supply "X" had an error)
1. See “Power checkout” on page 32.
System over recommended "X" current
(level-non-critical; system running too much
current on that voltage)
1. See “Power checkout” on page 32.
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 checkout” on page 32.
"X" V bus fault (level-critical; overcurrent
condition on "X" voltage bus)
1. See “Power checkout” on page 32.
12V "X" bus fault (level-critical; overcurrent
condition on 12 volt "X" voltage bus)
1. See “Power checkout” on page 32.
5V fault (level-critical; overcurrent condition
on 5 V subsystem)
1. See “Power checkout” on page 32.
240 VA bus fault (level-critical; overcurrent or
overvoltage condition in power subsystem)
1. See “Power checkout” on page 32.
