B1 R1.10 is not backward compatible with A1
A1 R1.00 will not be maintained after B1 release
A1 CPU works fine with L2 Data Center feature. For L3 features, we suggest to replace to B1 version.
HQ will provide free CPU daughter board to upgrade the A1 devices to B1 in the future*

Hardware Overview – Cooling System
Optimized cooling system to fit the heat dissipation design of data center:
– Customers can choose desired airflow by using different power and fan module which support Front-to-Back
Back-to-Front
P.S Different airflow modules cannot be mixed.
Hot Aisle
Cold Aisle Hot Aisle
Cold Aisle
Maintain the same airflow direction in a rack to avoid unexpected system crash and extend the lifespan
Provide the flexibility to turn the switch front panel to the same side of server ports for better cable management
Back-to-front air flow
Keep the same side for DXS-3600’s front panel with server ports to
- reduce cable length
- simplify cable management.
