The 7210 SAS system software controls the fans by monitoring the internal temperature of the chassis. The software manages the fan speed to maintain the internal temperature within the operational limits.
The 7210 SAS-D and 7210 SAS-D ETR platforms support fanless operation. The platforms have a fan for air circulation only, and not for cooling. The fan operates in automatic mode by default, and can be disabled by the operator.
The 7210 SAS-Dxp platforms are passively cooled and do not have fans.
