2.4.5 Heat Dissipation

The MA5623AR supports a high density of user access. In addition, the MA5623AR adopts
an optimal design to implement wind cooling heat dissipation.
Two fans are located in the right side of the MA5623AR, used for ventilation of the chassis in
the exhaust mode.
The airflow is as follows: the cool air enters the MA5623AR at the left side, and is blown
towards the right side by the fans, and finally, exits at the right side of the MA5623AR
