Replacing a TX Matrix Front Fan Tray

The upper and lower front fan trays are located above and below the front air filter. Each front fan tray weighs about 18.6 lb (8.4 kg).

To remove a front fan tray (see Figure 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.
Loosen the captive screws on the corners of the fan tray faceplate, using a Phillips (+) screwdriver, number 2.
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.
When the fans stop spinning, place one hand under the fan tray to support it, and pull the fan tray completely out of the chassis.
