    Removing the MX2020 Air Filter

    Caution: Do not run the router for more than a few minutes without the air filter in place.

    Caution: Always keep the air filter in place while the router is operating, except during replacement. Because the fans are very powerful, they could pull small bits of wire or other materials into the router through the unfiltered air intake. This could damage the router components.

    To remove the lower air filter—MX2020-FLTR-KIT-S:

    1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
    2. Loosen the two captive screws located on either side of the fan tray and air filter access door.

      Note: Removing the cables from the DC cable manager is not necessary to access the air filter.

      Caution: Do not run the router for more than 2 minutes without the air filter in place.

    3. Grasp the handle on the air filter, and pull the air filter straight out from the chassis.

      Note: The air filter has a built-in handle.

    4. Slide the air filter out of the chassis as shown in Figure 1.

    To remove the middle card cage cable manager air filter—MX2020-MID-FLTR-PNL-S:

    1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
    2. Move the cables from the middle card cage cable manager, if necessary.
    3. Loosen the two captive screws located on the front of the middle card cage cable manager door.

      Caution: Do not run the router for more than 2 minutes without the air filter in place.

    4. Open the cable manager door to get access to the air filter.
    5. Grasp the air filter, and pull the air filter straight out from the access door, (see Figure 2).

    To remove the PSM air filter—MX2000-FLTR-PWR:

    1. Attach an electrostatic discharge (ESD) grounding strap to your bare wrist, and connect the strap to one of the ESD points on the chassis.
    2. Loosen the two captive screws located on either side of the air filter and pull slightly out of the chassis.

      Caution: Do not run the router for more than 2 minutes without the air filter in place.

    3. Grasp the PSM air filter, and pull the air filter straight out from the chassis.
    4. Slide the air filter out of the chassis as shown in Figure 3.

      Note: The AC–powered MX2020 router has the same air filter.
