Removing the Rear Fan Tray

The rear fan tray is mounted vertically on the right side of the rear of the chassis.

The rear fan tray (model number RHTREARTRAY-T-S) weighs about 12 lb (5.4 kg).

To remove the rear fan tray, follow this procedure (see Figure 7 on page 15):

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. See “Preventing

Electrostatic Discharge Damage” on page 47.

2. Loosen the captive screws on the top and bottom of the fan tray faceplate, using

a Phillips (+) screwdriver, number 2.

3. Grasp the handles and pull the fan tray halfway out of the chassis.

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.

4. When the fans stop spinning, grasp the handles and pull the fan tray completely

out of the chassis.

CAUTION: To maintain proper cooling, do not operate the T1600 routing node with

the rear fan tray removed for more than one minute.
