Remove the Fan Tray

To remove the fan tray, follow this procedure (see Figure 26):

Do not remove the fan tray for more than a about one minute while the router is operating. The fans are the sole source of cooling, and the router can overheat when they are absent.

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. For more information about ESD, see “Prevent Electrostatic Discharge Damage” on page 134.

2.Loosen the thumbscrews above and below the handle on the fan tray faceplate, using a Phillips screwdriver if necessary.

3.Grasp the handle on the faceplate and slide the tray about halfway out of the chassis.

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.
