Remove the Fan Tray

The fan tray is located at the rear of the chassis, beneath the upper impeller assembly (see Figure 2). On some M40 routers, the tray is covered by a protective screen. You do not need to remove the screen before removing the fan tray from the chassis. The fan tray weighs approximately 5 lb (2 kg).

To remove the fan tray, follow this procedure (see Figure 69):

1. Attach an ESD strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
2. Unscrew the screws at the outer corners of the fan tray (not the screws that attach the protective screen), using a Phillips screwdriver if necessary.
3. Grasp the sides of the fan tray and pull firmly to slide it out of the chassis.
