Removing a Fan Tray

In the front of the chassis, the upper fan tray is located above the card cage, and the lower fan tray is located below the card cage. Each fan tray weighs about 7 lb (3.2 kg).

To remove the upper or lower fan tray (see Figure 5 and Figure 6, which illustrate the upper and lower fan trays):

1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis. For more information about ESD, see Preventing Electrostatic Discharge Damage.
2. Unwrap any cables on the cable management system and remove the cables from the tray. Arrange the cables so that they do not block the front of the cable management system and tray, and secure them with temporary fasteners so that they are not supporting their own weight as they hang from the connector.
3. If removing the lower front fan tray, simultaneously pull the two releases labelled PULL on the cable management system. Lift it up and outward to lock it in place.
4. Loosen the captive screw on each side of the fan tray faceplate.
5. Grasp both sides of the fan tray and pull it out approximately 1 to 3 inches.

   Warning: To avoid injury, keep tools and your fingers away from the fans as you slide the fan tray out of the chassis. The fans might still be spinning.

6. Pause for approximately 15 seconds to allow the fans to stop spinning.
7. When the fans stop spinning, press on the two latches located on the inside of the fan tray.
8. Place one hand under the fan tray to support it and pull the fan tray completely out of the chassis.
