Step 2 Loosen the two captive installation screws by turning them counterclockwise.
Step 3 Grasp the fan assembly with both hands and pull it outward; rock it gently if
necessary to unseat the power connector from the backplane.
Warning
When removing the fan tray, keep your hands and fingers away from the
spinning fan blades. Let the fan blades completely stop before you remove
the fan tray.
Step 4 Pull the fan assembly clear of the chassis and place it in a safe place.
Installing the Fan Assembly
Perform these steps to install the new fan assembly:
Step 1 Hold the fan assembly with the fans facing down and the FAN STATUS LED on
the left. (See Figure 5-7.)
Step 2 Place the fan assembly into the front chassis cavity so it rests on the chassis, and
then lift the fan assembly up slightly, aligning the top and bottom chassis guides.
Step 3 Push the fan assembly into the chassis until the power connector seats in the
backplane and the captive installation screws make contact with the chassis.
Step 4 Tighten the captive installation screws.
