Routine Maintenance Procedures for the T640 Router

Purpose

For optimum router performance, perform preventive maintenance procedures.

Note: Some components, such as the Connector Interface Panel (CIP) and the craft interface, require no maintenance.

Action

• 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, replacing them every 6 months. Do not run the router for more than a few minutes without the air filters in place.
