Power error messages

Table 17 describes power error messages and their suggested actions.

Note:

You will need to connect a keyboard and monitor to your appliance in order to see error messages.

Table 17. Power errors and actions

Message	Meaning	Action
Power supply X current fault	Level-critical; excessive current demand on power supply X	See "Power checkout".
Power supply X DC good fault	Level-critical; power good signal not detected for power supply X	Replace power supply X.
Power supply X fan fault	Level-critical; fan fault in power supply X	Replace power supply X
Power supply X fault	Level-critical; overcurrent condition exists	See "Power checkout".
Power supply X 12V fault	Level-critical; overcurrent condition detected	See "Power checkout".
Power supply X 3.3V fault	Level-critical; 3.3V power supply X had an error	See "Power checkout".
Power supply X 5V fault	Level-critical; 5V power supply X had an error	See "Power checkout" .
System over recommended X current	Level-non-critical; system running too much current on that voltage	See "Power checkout".
System running non-redundant power	Level-non-critical; system does not have redundant power	Check that all power supplies are operational Remove options from system Note: The system can continue to operate without redundancy protection if steps 1 and 2 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	Check connections to power subsystem Replace power supply Replace power backplane
System under recommended voltage on 3.3 v	Level-warning; 3.3 volt supply under nominal value	Check connections to power subsystem Replace power supply Replace power backplane
System under recommended X current	Level-non-critical; system drawing less current than recommended on voltage X	See "Power checkout".
X V bus fault	Level-critical; overcurrent condition on X voltage bus	Check for short circuit on X voltage bus See "Power checkout".
12V X bus fault	Level-critical; overcurrent condition on 12-V X voltage bus	Check for short circuit on 12-V X voltage bus See "Power checkout".
5V fault	Level-critical; overcurrent condition on 5-V subsystem	Check for short circuit on 5-V bus. See "Power checkout".
240 VA bus fault	Level-critical; overcurrent or overvoltage condition in power subsystem.	See "Power checkout".
