Installing a Routing Engine in an M20 Router

To install a Routing Engine in an M20 router, follow this procedure (see Figure 11):

  1. Attach an ESD wrist strap to your bare wrist and connect the wrist strap to one of the ESD points on the chassis.
  2. Place one hand under the Routing Engine to support it and grasp one of the extractor clips on the faceplate with the other hand.
  3. Align the rear of the Routing Engine with the guide rails inside the chassis and slide it in completely.    

    Be careful to align the Routing Engine correctly with the guide rails and push it in evenly. Damage can result if it gets lodged because of uneven movement.

  4. Press the extractor clips inward.
  5. If applicable, tighten the screws on the extractor clips, using a Phillips screwdriver. Be sure to tighten the screws enough to seat the Routing Engine properly.

    The Routing Engine might require several minutes to boot.

  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:

    For further information, see the JUNOS Protocols, Class of Service, and System Basics Command Reference.
