Troubleshooting cooling fans
Prerequisites
CAUTION: Many repairs may only be done by a certified service technician. You should only perform

NOTE: In the event of a problem with a particular fan, the fan number is referenced by the system’s management software,
allowing you to easily identify and replace the proper fan by noting the fan numbers on the cooling fan assembly.
Steps
