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.
2. Make sure that all modules are fully seated in their slots and that their latches are locked.
3. 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 module to fill the slot. Leaving a slot open negatively affects the airflow and can cause the
enclosure to overheat.
4. Try replacing each power supply one at a time.
5. Replace the controller modules one at a time.
6. Replace SFPs one at a time.
