Action
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.
1 Run the appropriate diagnostic test. See "Using Dell PowerEdge
Diagnostics" on page 131.
2 Turn off the system and attached peripherals, and disconnect the system
from the electrical outlet.
3 Open the system. See "Opening the System" on page 47.
CAUTION: The cooling fans are hot-pluggable. To maintain proper cooling while
the system is on, only replace one fan at a time.
4 Locate the faulty fan indicated by the diagnostic software or the fan
indicator that is blinking amber. For the identification number of each fan,
see "Removing and Installing the Heat Sink Cooling Fan" on page 87.
5 Ensure that the faulty fan's power cable is firmly attached to the fan power
connector. For a hot-plug fan, remove and reseat the fan. See "Cooling
Fans" on page 84.
NOTE: Wait 30 seconds for the system to recognize the fan and determine
whether it is working properly.
6 Reconnect the system to its electrical outlet, and turn on the system and
attached peripherals.
7 If the problem is not resolved, install a new fan. See "Cooling Fans" on
page 84.
