Troubleshooting cooling fans
Prerequisite
CAUTION: Many repairs may only be done by a certied 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.

If an error message is displayed indicating a fault with a specic memory module, go to step 14.
4 Enter System Setup and check the system memory setting. Make any changes to the memory settings, if needed.
If the memory settings match the installed memory but a problem is still indicated, go to step 14.
5 Turn o the system and attached peripherals, and disconnect the system from the electrical outlet.
6 Remove the system cover.
7 Remove the memory risers.
8 Check the memory channels and ensure that they are populated correctly.
9 Reseat the memory modules in their sockets.
10 Install the memory risers.
11 Install the system cover.
12 Reconnect the system to its electrical outlet, and turn on the system and attached peripherals.
13 Enter System Setup and check the system memory setting.
If the problem is not resolved, proceed with the next step.
14 If a diagnostic test or error message indicates a specic memory module as faulty, swap or replace the module with a known good
memory module.
