Voltage related system shutdown
Message Action
System shutoff due to x current over
max value (level-critical; system drawing
too much current on voltage x bus)
v See “Power checkout” on page 31.
System shutoff due to x V over voltage
(level-critical; system shutoff due to x
supply over voltage)
1. Check the power-supply connectors
2. Power supply.
System shutoff due to x V under voltage
(level-critical system shutoff due to x supply
under voltage)
1. Check the power-supply connectors.
2. Power supply.
System shutoff due to VRM x over
voltage
v
Replace VRM x .
System shutoff due to excessive (< 240
VA) loading
1. See “Power checkout” on page 31.
2. Cycle ac on/off.
Temperature related system shutdown
Message Action
System shutoff due to board over
temperature
(level-critical; board is over
temperature)
1. Ensure that the system is being properly cooled ; see “System
reliability considerations” on page 41.
2. Replace board.
System shutoff due to CPU x over
temperature
(level-critical; CPU x is over
temperature)
1. Ensure that the system is being properly cooled ; see “System
reliability considerations” on page 41.
2. Replace microprocessor x .
System shutoff due to CPU x under
temperature (level-critical; CPU x is under
temperature)
v Ambient temperature must be within normal operating
specifications
; see “Features and specifications” on page 4.
System shutoff due to DASD temperature
(sensor
x ) (level-critical; DASD area
reported temperature outside recommended
operating range)
v
Ensure that the system is being properly cooled ; see “System
reliability considerations” on page 41.
System shutoff due to high ambient
temperature
(level-critical; high ambient
temperature)
v Ambient temperature must be within normal operating
specifications
; see “Features and specifications” on page 4.
System shutoff due to system board
under temperature
(level-critical; system
board is under temperature)
v Ambient temperature must be within normal operating
specifications
; see “Features and specifications” on page 4.
DASD checkout
Message Action
Hard drive x removal detected
(level-critical; hard drive x has been
removed)
v
Information only, take action as appropriate.
