Troubleshooting cooling fans
Prerequisites
CAUTION: Many repairs may only be done by a certified service technician. You should only
perform troubleshooting and simple repairs as authorized in your product documentation, or as
directed by the online or telephone service and support team. Damage due to servicing that is
not authorized by Dell is not covered by your warranty. Read and follow the safety instructions
that came with the product.
Steps
1.
Open the system cover.
CAUTION: The cooling fans are hot-swappable. To maintain proper cooling while the system
is on, only replace one fan at a time.
2.
Locate the faulty fan indicated by the Embedded Server Management (ESM).
3.
Replace the fan or the fan's power cable.
NOTE: Wait at least 30 seconds for the system to recognize the fan and determine whether it is
working properly.
4.
If the problem is not resolved, install a new fan.
5.
If the fan functions properly, close the system cover.
