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

    To remove the AC or DC PSMs (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 power switch on each PSM to the off (O) position. On a DC-powered router, move the DC power switch on each PSM to the off (O) position.

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

    3. Loosen the two captive screws that secure the PSM to the chassis. While grasping the handle on the PSM faceplate with one hand, use your other hand to guide the PSM.
    4. Pull the PSM straight out of the chassis.

      Caution: Do not touch the power connector on the back of the PSM. It can get damaged.

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