Replacing Air Filters on J4350 and J6350 Routers

The front panel of J4350 and J6350 Services Routers contains an air intake grid with a protective cover and a filter, as shown in Figure 102.

We recommend changing the filter every 6 months. However, the optimal filter replacement interval can vary depending on the environment where the router is located. If temperature alarms appear, inspect the air filter.

To replace the air filter:

1. Remove the filter cover by squeezing the plastic tabs on either side of the filter cover.
2. Pull the filter cover away from the chassis.
3. Remove the old filter.
4. Place the new filter in the opening.
5. Replace the filter cover by pressing it until it clicks into place.
