Only trained and qualified personnel should be allowed to install, replace, or service this equipment. Statement

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 (with the adapter module detatched), is ready for installation. There is a
time constraint when you remove and replace a 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 Grasp the front handle with one hand and place your other hand underneath the fan tray to support it. Hold
the fan tray with the fans facing to the right.
Step 2 Place the fan tray in the fan tray bay such that it rests on the chassis, and then lift the fan tray up slightly,
aligning the top and bottom guides.
