Installing a Routing Engine in an M20 Router

To install a Routing Engine in an M20 router (see Figure 6):

  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.
  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. After the Routing Engine boots, check the Routing Engine LEDs on the craft interface to verify that the appropriate green LED labeled ONLINE is lit.

    You can also issue the following CLI command to verify correct Routing Engine functioning:
