Removing a Cooling Fan
WARNING: Do not attempt to operate the system without the cooling fans.
WARNING: The cooling fan can continue to spin for some time after the system
has been powered down. Allow time for the fan to stop spinning before removing
it from the system.
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 It is recommended to turn off the system, including any attached
peripherals, and disconnect the system from its electrical outlet.
2 Open the system. See “Opening the System” on page 246.
3 Disconnect the fan’s power cable from the power distribution board 1.
Note the routing of the cable through the cable tie as you remove them
from the system. You must route these cables properly when you
replace them to prevent the cables from being pinched or crimped.
4 Directly lift the cooling-fan cage out of the chassis. See Figure 3-68.
