Removing the Rear Lower Impeller Assembly
To remove the rear lower impeller assembly, follow this procedure (see Figure 75):
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.
Loosen the thumbscrew at each corner of the impeller cover, using a Phillips
screwdriver if necessary.
3.
Grasp the thumbscrews at opposite corners of the impeller cover and slide the
assembly halfway out of the chassis.
CAUTION:
To avoid injury, as you slide the assembly out of the chassis do not touch
any part of the impeller behind the front panel—the impeller might still be spinning.
4.
When the impeller is no longer spinning, slide the assembly completely
out of the chassis.
