Figure 219: Installing the PSM Air Filter
Maintaining the MX2020 Air Filter
Purpose
For optimum cooling, verify the condition of the air filter.
Action
•
Regularly inspect the air filter. A dirty air filter restricts airflow in the unit, producing a negative effect
on the ventilation of the chassis. The filter degrades over time. You must replace the filter every 6
months.
CAUTION: Always keep the air filter in place while the router is operating. 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.
