4Align the fan tray connector and the backplane connector.

5Use the guide pin on the fan tray and the guide pin holes on the backplane of the chassis and gently push the fan tray inward until the fan tray connector and backplane connector engage.

You feel a slight resistance as the connectors engage.

CAUTION: If the resistance is too great, the fan tray connector and backplane connector may not be aligned properly. Do not force the fan tray inward or you can damage the connectors. If necessary, remove and reinsert the fan tray, ensuring that the connectors are properly aligned.

6Verify that the fan tray is flush with the back of the chassis. If the fan tray and the chassis are not aligned, remove the fan tray and reseat it.

7Using a flat-blade screwdriver, tighten the spring-loaded screws to secure the fan tray to the chassis (Figure 2).

The fans begin rotating the moment that you power on the chassis or insert a fan tray into a powered-on chassis.

8Visually inspect all installed fans to verify that each is turning without interruption. If a fan is not running, shut the power off and remove and reinsert the fan tray.
