Removing the Craft Interface from the Front Impeller Assembly

If you are replacing the front impeller assembly and the replacement assembly does not have a craft interface panel on the front, you must transfer the craft interface from the removed assembly to the replacement assembly. To remove the craft interface from the removed impeller assembly, follow this procedure:

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. Place the removed and replacement impeller assemblies top side up on antistatic mats.
3. If not immediately transferring the craft interface panel to the replacement assembly, place an antistatic mat or electrostatic bag on a flat, stable surface to receive it.
4. Using a Phillips screwdriver, remove the screws from the three semicircular metal tabs on the back of the craft interface that secure it to the impeller assembly (see Figure 72). Save the screws.
5. Grasp the ends of the craft interface, pull upward to release the hooks on the back of it from the windows on the front of the impeller assembly, then pull it toward you to free the craft interface completely (see Figure 73). If not immediately transferring it to a replacement impeller assembly, place it in the electrostatic bag or on the antistatic mat.
