To remove a fan tray (see Figure 1):

Caution

Do not remove both fan trays for more than 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 ESD grounding strap to your bare wrist and connect the strap to one of the ESD points on the chassis.
  2. Loosen the thumbscrew at the top of 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.Caution

    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.

  4. Place one hand under the fan tray to support it and slide the tray completely out of the chassis after the fans stop spinning.
