Installing/removing a fan tray
CAUTION:
• Install two fan trays of the same model on the switch. Do not power on the switch when it does
not have fan trays or has only one fan tray installed.
• If both fan trays fail during operation, replace them within 2 minutes while the switch is operating.
• If one fan tray fails and the ambient temperature is not higher than 27°C (80.6°F), replace the fan
tray within 24 hours. If one fan tray fails and the ambient temperature is higher than 27°C
(80.6°F), replace the fan tray immediately. Make sure the failed fan tray is in position before the
replacement.
The switch comes with empty fan tray slots. Choose the fan tray models based on the ventilation
requirement of the site. The air flow direction varies by fan tray model.

The LSWM1FANSCE has a blue handle and provides power-to-port air flow.
•
The LSWM1FANSCBE has a red handle and provides port-to-power air flow.
