Replacing a Fan Tray
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.
If hot swapping the fan tray, please be aware that there are time-critical aspects to parts of the procedure. To
ensure proper preparation, please read through all the steps in the procedure before attempting the replacement.
Also, make sure you understand all the precautions in these steps as well as those on page 10.
Prepare the New Fan Tray
1. Unpack the new fan tray.
2. Inspect the new fan tray to verify that it is undamaged.
3. Place the new fan tray in a safe, accessible place near the chassis, ready for prompt insertion.
4. Locate a #2 Phillips or cross-head screwdriver.
Remove the Old Fan Tray
1. Loosen the fan tray's fastening screws.
At the front of the W-6000 controller, use the screwdriver to loosen both of the fastening screws on the
faceplate of the installed fan tray. The screws loosen with counter-clockwise rotation, but are captive and
cannot be fully removed.
2. Disengage the fan tray.
Grasp the module handle firmly and draw the fan tray forward from its slot. There may be moderate resistance
as the module comes free from its connections with the chassis backplane, but do not use excessive force.
When the module is fully disengaged from the backplane, power to the working fans is lost and they will
gradually stop spinning.
CAUTION: The fans will continue to spin for a short while, even though there is no power to them. Wait for the fans to stop
spinning before removing the fan tray.
Also, when hot swapping, once the fans stop spinning, the W-6000 controller will continue to operate, though heat will begin
to build in the operational components. From this point, there is a limited time (one minute) before installation of the new fan
tray must be completed.
The one minute limit must be adhered to since the W-6000 controller does not have a thermal shutdown function. If you cannot
replace the fan tray within one minute, shut down the controller.
3. Once disengaged, the fan tray should easily slide out of the chassis. Fully remove the fan tray and place it
safely aside.
Insert the New Fan Tray
1. Pick up the new fan tray by the handle provided on its front panel.
2. Carefully insert the fan tray into the chassis fan tray slot.
Align the rear of the fan tray with the guide rails in the chassis fan tray slot and slide it gently toward the
backplane. The module should slide in easily most of the way.
3. Engage the fan tray.
