    Removing the MPCs without an Adapter Card Before Installing an MX2020 Router with a Pallet Jack

    To remove an MPC without an ADC (see Figure 1):

    1. Have ready an antistatic mat for the MPC. Also have ready rubber safety caps for each MPC that uses an optical interface on the MPC 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. Simultaneously turn both the knobs counterclockwise to unseat the MPC from the ADC.
    4. Grasp both knobs, and slide the MPC straight out of the ADC.
    5. Place one hand around the front of the MPC and the other hand under it to support it. Slide the MPC completely out of the ADC, and place it on the antistatic mat or in the electrostatic bag.

      Caution: The weight of the MPC is concentrated in the back end. Be prepared to accept the full weight—up to 18.35 lb (8.32 kg)—as you slide the MPC out of the ADC.

      When the MPC is out of the ADC, do not hold it by the knobs, bus bars, or edge connectors. They cannot support its weight.

      Do not stack MPCs on top of one another after removal. Place each one individually in an electrostatic bag or on its own antistatic mat on a flat, stable surface.
