Reinstalling the PCGs

The router has two PCGs installed in the slots labeled PCG 0 and PCG 1 at the rear of the chassis, as shown in Figure 3. To reinstall the PCGs, follow this procedure (see Figure 52):

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 one hand under the PCG to support it and grasp the thumbscrew on the faceplate with the other hand.
3. Align the rear of the PCG with the guides inside the chassis and slide it in completely.
4. Tighten the thumbscrew on the faceplate to seat the PCG firmly in the chassis.
5. Repeat the procedure to reinstall the second PCG.
