Reinstalling the Fan Tray

The fan tray, which includes the cable management system, is located on the front of the chassis, just above the air filter, as shown in Figure 1. To reinstall it, follow this procedure (see Figure 47):

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. Make sure the router is attached to a proper earth ground. For more information about ESD, see Preventing Electrostatic Discharge Damage.
2. Grasp the sides of the fan tray and align the rear of the tray with the guides inside the chassis.
3. Slide the fan tray all the way into the chassis.
4. Tighten the thumbscrew at each end of the cable management system.
