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)
