DXS-3600 Series Selectable Airflow:
Hardware Overview – Cooling System
Optimized cooling system to fit the heat dissipation design of data center:
– The DXS-3600 switches allow users to change airflow by using different power and fan module sets Front-to-Back Back-to-Front
P.S Different airflow module cannot be mixed.
Hot Side
Cold Side
To consist airflow on the same rack to avoid unexpected system crash and extend the lifespanProvide the flexibility to turn the switch front panel to the same side of server ports for better cable management
By changing DXS-3600 direction to opposite side to support the same air-flow and shorten the cable distance with rack servers
