    Maintaining the Air Filter in EX9208 Switches

    Purpose

    For optimum cooling, verify the condition of the air filters.

    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 switch is operating. Because the fans are very powerful, they could pull small bits of wire or other materials into the switch through the unfiltered air intake. This could damage the switch components.

    • Use spare filters within one 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.
