Reinstalling the Front Impeller Assembly

The front impeller assembly, which includes the craft interface, is located at the top of the chassis front, as shown in Figure 1. To reinstall it, follow this procedure (see Figure 45):

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 impeller assembly and align the rear of the assembly with the guides inside the chassis.
3. Slide the impeller assembly all the way into the chassis.
4. Using a Phillips screwdriver, tighten the captive screw at each corner of the craft interface.
