Reinstalling the Rear Upper Impeller Assembly

The rear upper impeller assembly is installed at the top of the chassis rear, as shown in Figure 2. To reinstall the assembly, follow this procedure (see Figure 49 and Figure 50, which show the two types of impeller that can be installed):

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.Slide the assembly all the way into the chassis.

3.Tighten the thumbscrew at each corner of the impeller cover.
