For optimum router performance, perform preventive maintenance procedures.
Inspect the installation site for moisture, loose wires or cables, and excessive dust.
Make sure that airflow is unobstructed around the router and into the air intake vents.
Check the status-reporting devices on the craft interface—System alarms and LEDs.
Inspect the air filter at the left rear of the router, replacing it every 6 months for optimum
cooling system performance. Do not run the router for more than a few minutes without
the air filter in place.
