    Installing a PCG in an M40e Router

    To install a PCG (see Figure 1):

    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. For more information about ESD, see Preventing Electrostatic Discharge Damage to an M Series, MX Series, or T Series Router.
    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. Verify that the green LED labeled OK lights steadily, which takes about 3 seconds.

      You can also verify correct PCG functioning by issuing the show chassis environment pcg command, as described in Maintaining the M40e PCGs.

    6. Reinstall the rear component cover and tighten the thumbscrew at each corner to secure it to the chassis. For complete instructions, see Reinstalling the M40e Components into the Chassis.

      Caution: To maintain proper airflow and provide electromagnetic shielding, do not operate the router without the rear component cover in place.
