Routine Maintenance Procedures for the T4000 Router



For optimum router performance, perform preventive maintenance procedures.


On a regular basis:

  • 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.

  • Inspect the air filters at the bottom front and left rear of the router. Do not run the router for more than a few minutes without the air filters in place.

    Check the air filters regularly for dust and debris. As a general guideline, we recommended that you replace the filter elements every 6 months for routers operating in a typical environment. The filter elements degrade over time, and replacement intervals will vary by operating environment.
