Installing the Front Impeller Assembly

To install the front impeller assembly, follow this procedure (see Figure 74):

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.
