Voltage related system shutdown

Message
System shutoff due to "X" current over
max value (level-critical; system drawing
too much current on voltage "X" bus)
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)
System shutoff due to VRM "X" over
voltage
System shutoff due to excessive (< 240
VA) loading

Temperature related system shutdown

Message
System shutoff due to board over
temperature (level-critical; board is over
temperature)
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)
System shutoff due to system board
under temperature (level-critical; system
board is under temperature)
