Routine Maintenance Procedures for EX9200 Switches
For optimum performance of an EX9200 switch, 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 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.
