Overheating
Overheating is a potentially serious condition because the excessively high temperatures can lead to
physical drive failure and controller malfunction.
Overheating usually results from:
•
Fan failure
•
Inadequate air circulation around the Pegasus unit
Fan Failure
The larger fan on the back of the Pegasus unit cools the physical drives and the RAID controller. The
smaller fan cools power supply. Cooling fans are not field-replaceable. If there is any problem with a
cooling fan, contact Technical Support to make arrangements for a repair.
