    Installing a Routing Engine in an M40e Router

    To install a Routing Engine in an M40e router:

    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.
    2. Verify that the extractor clip at each end of the Routing Engine is flipped toward the outer edge of the unit. If necessary, use your thumbs to push and hold the red tab on each extractor clip toward the outer edge, then push the ends of the extractor clips outward.
    3. Place one hand under the Routing Engine to support it and grasp one of the extractor clips on the faceplate with the other hand.
    4. Align the rear of the Routing Engine with the guide rails inside the chassis and slide it in completely.

      Caution: Align the Routing Engine carefully with the guide rails and push it in evenly. Damage can result if the Routing Engine gets lodged in the rails because of uneven movement.

    5. Press the extractor clip at each end of the Routing Engine inward to seat the unit firmly in the chassis.
    6. Check the host module LEDs on the craft interface to verify that the green LED labeled ONLINE is lit for the host module to which the Routing Engine belongs (M40e Craft Interface Description shows the LEDs).

      You can also verify correct Routing Engine functioning by issuing the show chassis routing-engine command described in Maintaining the M40e Host Module Components.

    7. 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.
