Removing an MX80 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. |
The air filter is installed on the right side of the fan tray. To remove the air filter (see Figure 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.
- Remove the fan tray as described in Removing an MX80 Fan Tray.
- Press the release tab on the rear of the fan tray to release the air filter.
- Grasp the sides of the air filter, and slide it away from the fan tray faceplate.
