switches. If the fan tray of a switch fails, order a compatible fan tray to replace the failed one.
Air filters

CAUTION:
Clean air filters periodically (at least once every three months) to guarantee adequate ventilation and
avoid over-temperature.
To prevent dusts from entering the chassis, you can configure air filters for the switch as needed and
