For optimum cooling, verify the condition of the air vents. Dust can clog air vents, reducing
cooling system efficiency.
On a regular basis, check the vents and clean them as necessary.
For optimum cooling, verify the condition of the air filter.
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.
Use spare filters within 1 year of manufacture. Check the date of manufacture printed
on the filter. Store spare air filters in a dark, cool, and dry place. Storing air filters at
higher temperatures, or where they can be exposed to ultraviolet (UV) radiation,
hydrocarbon emissions, or vapors from solvents, can significantly reduce their life.
