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.
