    Removing the CB-REs Before Installing the MX2020 Router with a Router Transport Kit

    To remove a CB-RE (see Figure 1):

    1. Have ready an antistatic mat for the CB-RE. Also have ready rubber safety caps for each SFP that uses an optical interface on the CB-RE that you are removing.
    2. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to an approved site ESD grounding point. See the instructions for your site.
    3. Open both ejector handles simultaneously to unseat the CB-RE.
    4. Grasp the handles, and slide the CB-RE straight out of the card cage halfway.
    5. Place one hand around the front of the CB-RE and the other hand under it to support it. Slide the CB-RE completely out of the chassis, and place it on the antistatic mat or in the electrostatic bag.

      Caution: The weight of the CB-RE is concentrated in the back end. Be prepared to accept the full weight—up to 15 lb (6.8 kg)—as you slide the CB-RE out of the chassis.

      When the CB-RE is out of the chassis, do not hold it by the ejector handles, bus bars, or edge connectors. They cannot support its weight.

      Caution: Do not stack CB-REs on one another after you remove them. Place each component on an antistatic mat resting on a stable, flat surface.
