As referred to in Table 14, the following table lists power supply module faults and recommended actions.
Table 16 Power supply faults and recommended actions
Fault Recommended action
Power supply fan warning or failure, or power supply
warning or failure. Event code 168.
• Check that all of the fans are working using SMU.
• Make sure that no slots are left open for more than 2
minutes. If you need to replace a module, leave the
old module in place until you have the replacement,
or use a blank cover to close the slot. Leaving a slot
open negatively affects the airflow and might cause
the unit to overhead.
• Make sure that the controller modules are properly
seated in their slots and that their latches are locked.
Power supply module status is listed as failed or you
receive a voltage event notification. Event code 168.
• Check that the switch on each power supply module
is turned on.
• Check that the power cables are firmly plugged into
both power supply and into an appropriate electrical
outlet.
• Replace the power supply module.
