Appendix D Cooling system 

 

CAUTION: 

To guarantee heat dissipation, you must install fan trays of the same model for the switch. 

 

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. 

Table 31 Cooling system for the switch 

Available fan trays 

Airflow direction 

LSPM1FANSA 

From the power module side to the port side 

LSPM1FANSB 

From the port side to the power module side
