Reinstall 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, which should already be in place on the tray. To reinstall the tray, follow this procedure (see Figure 43):

1. Attach an ESD strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
2. Slide the fan tray into the chassis.
3. Align the screws at the corners of the fan tray with the mounting holes at the edges of the opening and use a Phillips screwdriver to tighten the screws.
