Routine Maintenance Procedures for EX9200 Switches

Purpose

For optimum performance of an EX9200 switch, perform preventive maintenance procedures.

Action

  • Inspect the installation site for moisture, loose wires or cables, and excessive dust. Make sure that airflow is unobstructed around the switch and into the air intake vents.

  • Check the status-reporting devices on the craft interface in EX9200 switches—system alarms and LEDs.

  • Inspect the air filter or fan tray at the rear of the switch, replacing it every 6 months for optimum cooling system performance. Do not run the switch for more than a few minutes without the air filter or fan tray in place.
