Installing the Craft Interface on the Front Impeller Assembly

To attach the craft interface to the front 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” on page 226.

2.Place the replacement impeller assembly top side up on an antistatic mat on a flat, stable surface.
