Removing the M7i Fan Tray

The fan tray is located on the back of the chassis. It weighs approximately 1.6 lb (0.7 kg).

To remove the fan tray (see Figure 56 on page 118):

Attach an electrostatic discharge (ESD) grounding strap to your bare wrist and connect
the strap to one of the ESD points on the chassis. Verify that the router is attached to
a proper earth ground.

Loosen the thumbscrew securing the fan tray, using a Phillips screwdriver if necessary.

Grasp the handle on the fan tray and pull firmly to slide it halfway out of the chassis.
