Replacing the MX960 Air Filter
Removing the MX960 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 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.
- Unwrap any cables on the standard cable
manager and remove the cables from the tray. Arrange the cables so
that they do not block the front of the cable manager and tray, and
secure them with temporary fasteners so that they are not supporting
their own weight as they hang from the connector.

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

Caution: Do not let fiber-optic cable hang free from the connector. Do not allow fastened loops of cable to dangle, which stresses the cable at the fastening point.
- Simultaneously pull the two releases labeled PULL on the standard cable manager. Lift it up and outward to lock it in place to access the air filter.
- Slide the air filter tray out of the chassis.
- Lift the air filter out of the air filter tray.
