Routine Maintenance Procedures for EX9253 Switches
For optimum performance of an EX9253 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 switch—alarms and LEDs.
Inspect the air filter and fan tray, replacing the air filter 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 trays in place.
