Periodic Inspection and Cleaning
Periodic Inspection and Cleaning
Periodic inspection and cleaning of the external surface of the router is recommended to minimize the
negative impact of environmental dust or debris. The frequency of inspection and cleaning is dependent
upon the severity of the environmental conditions, but a minimum of every six months is recommended.
Cleaning involves vacuuming of router air intake and exhaust vents. See the “Fans, Ventilation, and
Airflow” section on page 1-17.
Caution Sites with ambient temperatures consistently above 25°C or 77°F and with potentially high levels of dust
or debris may require periodic preventative maintenance cleaning.
