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.
