Resolving voltage and temperature warnings
1.
Check that all of the fans are working by making sure the Voltage/Fan Fault/Service Required LED on
each power supply module is off, or by using the SMC to check enclosure health status.
In the lower corner of the footer, overall health status of the enclosure is indicated by a health status
icon. For more information, point to the
System
tab and select
View System
to see the System panel.
You can select
Front
,
Rear
, and
Table
views on the System panel. If you hover over a component, its
associated metadata and health status displays onscreen.
See
Options available for performing basic steps
on page 46 for a description of health status icons
and alternatives for monitoring enclosure health.

Make sure that all modules are fully seated in their slots and that their latches are locked.
3.

blank module to fill the slot. Leaving a slot open negatively affects the airflow and can cause the
enclosure to overheat.

Try replacing each power supply one at a time.
5.
Replace the controller modules one at a time.
