Removing an E320 Fan Tray

To remove the fan tray:

Place a flathead screwdriver in the groove where the top bezel meets the chassis on the top of the system, and lever the top bezel off the front of the system.
With an appropriate screwdriver, loosen the captive screws located at the corners of the fan tray.

Warning: Do not place your fingers near the fans when removing the fan tray. The blades might still be moving.
Pull the fan tray halfway out of the shelf until it stops on the safety catch.
Pull both red safety handles upward while gripping the sides of the fan tray and pull the tray out slightly until the safety catch is released.
Place one hand under the fan tray and the other on the front handle and continue to pull the fan tray out of the chassis.
Use two hands to hold the fan tray after it comes out of the chassis.
