System shutdown
Refer to the following tables when experiencing system shutdown related to voltage
or temperature problems.
Voltage related system shutdown
System under recommended voltage for "X"
v
(level-warning; indicated
voltage supply under nominal value; value
for "X" can be +12, -12, or +5)
1. Check connections to power subsystem
2. Replace power supply
3. Replace power backplane
System under recommended voltage on 3.3
v
(level-warning; 3.3 volt
supply under nominal value)
1.
Check connections to power subsystem
2. Replace power supply
3. Replace power backplane
System under recommended X current
(level-non-critical; system drawing less
current than recommended on voltage "X")
1. See “Power checkout” on page 26.
"X" V bus fault (level-critical;
overcurrent condition on "X" voltage bus)
1. Check for short circuit on "X" voltage bus
2. See“Power checkout” on page 26.
12V "X" bus fault (level-critical;
overcurrent condition on 12 volt "X" voltage
bus)
1. Check for short circuit on 12 volt "X" voltage bus
2. See “Power checkout” on page 26.
5V fault (level-critical; overcurrent
condition on 5 V subsystem)
1. Check for short circuit on 5 v bus
2. See“Power checkout” on page 26.
240 VA fault (level-critical; overcurrent
or overvoltage condition in power
subsystem)
1. See “Power checkout” on page 26.
Message Action
System shutoff due to "X" current over
max value
(level-critical; system
drawing too much current on voltage "X"
bus)
1.
See “Power checkout” on page 26.
System shutoff due to "X" current under
min value
(level-critical;
current on voltage bus "X" under minimum
value)
1. See “Power checkout” on page 26.
System shutoff due to "X" V over voltage
(level-critical; system shutoff due to "X"
supply over voltage)
1. Check power supply connectors
2. Replace power supply
3. Replace power backplane
System shutoff due to "X" V under voltage
(level-critical system shutoff due to "X"
supply under voltage)
1. Check power supply connectors
2. Replace power supply
3. Replace power backplane
