Routine Maintenance Procedures for EX9251 Switches

 

Routine Maintenance Procedures for EX9251 Switches

Purpose

For optimum performance of an EX9251 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 front panel in EX9251 switches—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.

Maintaining the Routing Engine in EX9251 Switches

For optimum switch performance, verify the condition of the Routing Engine on a regular basis.

On a regular basis:

  • Check the LEDs on the front panel to view information about the status of the Routing Engine.

  • To check the status of the Routing Engine on the switch, issue the show chassis routing-engine command. The output is similar to the following:
