Removing the Front Impeller Assembly

The front impeller assembly, which includes the craft interface, is located at the front of the chassis above the FPC card cage, as shown in Figure 1. The assembly weighs approximately 14.5 lb (6.6 kg).

To remove the front impeller assembly, follow this procedure (see Figure 42):

1.Place an electrostatic bag or antistatic mat on a flat, stable surface.

2.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.

3.Using a Phillips screwdriver, loosen the captive screw at each corner of the craft interface.
