Power supply faults and recommended actions
Events sent as indications to SMI-S clients
If the storage system’s SMI-S interface is enabled, the system will send events as indications to SMI-S
clients so that SMI-S clients can monitor system performance. For information about enabling the SMI-S
interface, see the chapter about configuring the system in the SMU Reference Guide.
The event categories below pertain to FRU assemblies and certain FRU components.
Table 1 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 the
SMU.
• Make sure that no slots are left open for more
than two 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
overheat.
• Make sure that the power supply 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 .
• For each power supply module with a switch,
check that the switch is turned on.
• Check that the power cables are firmly plugged
into both power supply and into an appropriate
and functional electrical outlet.
• Replace the power supply module.
Power LED is off. Same as above.
Voltage/Fan Fault/Service Required LED is on. Replace the power supply module.
