System shutdown

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

Voltage related system shutdown

Message
System shutoff due to "X"
V over voltage (level-
critical; system shutoff due
to "X" supply over voltage)
System shutoff due to "X"
V under voltage (level-
critical system shutoff due
to "X" supply under voltage)

Temperature related system shutdown

Message
System shutoff due to CPU
"X" over temperature
(level-critical; CPU "X" is
over temperature)
System shutoff due to CPU
"X" under temperature
(level-critical; CPU "X" is
under temperature)
System shutoff due to
DASD temperature (sensor
X) (level-critical; DASD area
reported temperature outside
recommended operating
range)
System shutoff due to high
ambient temperature (level-
critical; high ambient
temperature)
