Message
Power Supply "X" fault
(level-critical; power supply "X" has been removed or has
encountered some other fault)
Power Supply "X" overvoltage fault
(level-critical)
Power Supply "X" AC power removed, early power-off
warning
(level-critical; a power supply has been unplugged or has
been installed without an ac cord)
System running non-redundant power
(level-non-critical; system does not have redundant power)
System under recommended voltage for "X" v
(level-warning; indicated voltage supply under nominal
value; value for "X" can be +12, -12, or +5)
System under recommended voltage on 3.3 v
(level-warning; 3.3 volt supply under nominal value)
"X" V bus fault
(level-critical; overcurrent condition on "X" voltage bus)
12V "X" bus fault
(level-critical; overcurrent condition on 12 volt "X" voltage
bus)
5V fault
(level-critical; overcurrent condition on 5 V subsystem)

System shutdown

Refer to the following tables when experiencing system shutdown related to voltage
or temperature problems.

Voltage related system shutdown

Message
