When unmating the connector, gently move the fan tray from side to side, if necessary. The fans are equipped
with a braking mechanism that fully stop the blades within three seconds of being de-energized (You will not
be able to visualy inspect the fan to see whether the blades are spinning or not).
Step 5
Place your other hand underneath to support the bottom of the fan tray and then slide it out of the bay
completely.
The entire fan tray assembly is removed from the chassis (including the adapter).
What to do next
Set the removed fan tray aside and immediately proceed with installing the replacement or spare fan tray.

Statement
1030
Warning
No user-serviceable parts inside. Do not open.
Statement 1073
Warning
Installation of the equipment must comply with local and national electrical codes.
Statement 1074
Warning
Before you begin
Ensure that a replacement fan tray assembly (with the adapter module intact), is ready for installation. There
is a time constraint when you remove and replace the fan tray in a system that is powered on - if you have
enabled the service mode prior to servicing, fan-less operation can be safely assured for four minutes only.
You may need a Phillips-head screwdriver to loosen the captive installation screws.
Procedure
Step 1
On the replacement fan tray assembly, ensure that the two screws securing the fantray to the adapter (on the
side with the fan STATUS LEDs) are tight. Be careful not to overtighten the screws.
Step 2
Grasp the rear handle with one hand and place your other hand underneath, to support the botton of the fan
try assembly (such that the side with the STATUS LED is inserted first).
