    Removing the Power Distribution Modules Before Installing an MX2020 Router with a Router Transport Kit

    Remove the topmost PDM (PDM3) first, and then work your way downward. To remove an AC or DC PDM (see Figure 1 and Figure 2).

    1. 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.
    2. On an AC-powered router, move the AC circuit breaker from the power source to the off (O) position. On a DC-powered router, move the DC circuit breaker from the power source to the off O position.

      We recommend this precaution even though the PDMs are not connected to power sources.

    3. Loosen the two captive screws on the PDM faceplate. Pull the two spring-loaded locking levers away from the chassis until it stops.

      Note: PDM3 and PDM1 locking levers are pulled down to release from chassis, and PDM0 and PDM2 locking levers are pulled up to release from chassis.

      The PDM is extended slightly away from the chassis.

    4. With both hands, grasp the two handles and gently pull the PDM straight out of the chassis.

      Caution: Do not touch the power connector in the back of the PDM. They can get damaged.

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