Hardware Maintenance Manual: Netfinity 7100 – Type 8666
Message
12V "X" bus fault (level-critical; overcurrent
condition on 12 volt "X" voltage bus)
5V fault (level-critical; overcurrent condition on
5 V subsystem)
240 VA bus fault (level-critical; overcurrent or
overvoltage condition in power subsystem)
Message
System powered off due to "X" current over
max value (level-critical; system drawing too
much current on voltage "X" bus)
System shutoff due to "X" current under min
value (level-critical; current on voltage bus "X"
under minimum value)
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 powered off due to faults on each
power supply.
Message
System shutoff due to board over temperature
(level-critical; processor 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)
