Removing the Routing Engine Panel and Fan Tray

To remove the Routing Engine panel and fan tray, follow this procedure (see Figure 55):

1. Place an electrostatic bag or antistatic mat on a flat, stable surface.
2. 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. For more information about ESD, see Preventing Electrostatic Discharge Damage.
3. Loosen the thumbscrews on the right side of the Routing Engine panel, using a Phillips screwdriver if necessary.
4. Grasp the handle between the thumbscrews and pull the unit halfway out of the chassis.

   Caution: To avoid injury, do not touch the fans with your fingers or any tool as you slide the fan tray out of the chassis—they might still be spinning.

5. Place one hand under the fan tray to support it, slide the tray completely out of the chassis after the fans stop spinning, and place it on the antistatic mat or in the electrostatic bag.
