Routine Maintenance Procedures for EX9208 Switches

For optimum performance of an EX9208 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—System alarms and LEDs.
Inspect the air filter at the left 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 in place.
