Cooling system 

 

CAUTION: 

The chassis and power supplies use separate air aisles. Make sure the two aisles are not blocked 
when the switch is operating. 

 

To dissipate heat timely and ensure system stability, the switch uses the front-rear air aisle cooling 
system. Consider the site ventilation design when you plan the installation site for the switch.
