Installing an MX2020 Air Filter

 

The MX2020 router has three air filters: a lower air filter, middle card cage cable manager air filter, and a Power Supply Module (PSM) air filter. These filters are included in the MX2020 Filter Kit (MX2020-FLTR-KIT-S). For chassis with 240 V China power supplies, you’ll need a different PSM air filter—MX2000-FLTR-PWR.

Use these procedures to install the air filters.

To install the lower air filter:

  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. Ensure that the air filter is right side up.
  3. Open the fan tray and air filter access door, located at the bottom of the chassis.
  4. Grasp the handle on the air filter and insert into the chassis until it stops, (see Figure 1).
  5. Close the access door and tighten the two captive screws to secure.
  6. Lower the cable manager back into position, and rearrange the cables in the cable manager.

To install the middle card cage cable manager air filter:

  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, and open.Caution

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

  4. Grasp the air filter, and slide the bottom of the air filter into the channel of the access door, (see Figure 2).

  5. Push the air filter in place, close the door, and tighten the two captive screws.
  6. Replace the cables in the middle card cage cable manager, if necessary.

To install the PSM air filter:

  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. Ensure that the air filter is right side up.
  3. Grasp the PSM air filter and insert into the chassis until it stops, (see Figure 3).
  4. Tighten the two captive screws to secure.
