Routine Maintenance Procedures

For optimum router performance, perform the following preventive maintenance procedures regularly:

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, LEDs, and LCD. See Craft Interface on page 27.

Inspect the air filters at the bottom front and left rear of the router, cleaning or replacing it as needed for optimum cooling system performance. Do not run the router for more than a few minutes without the air filters in place. For maintenance instructions, see “Maintaining the Air Filter” on page 128.
