.edge is cooled by five temperature-controlled fans (fitted behind the front grill). There are three large fans (to cool the processing blades) plus two smaller fans (to cool the rear I/O plates).

The fan tray is removable and can be exchanged from the front of the frame. See Replacing the Fan Tray for instructions.

The fan activity is controlled automatically by the master processing blade. Mid-plane connections between the blades are used to determine the number of blades and their current temperatures. This, in turn, sets the fan speed.

Airflow RequirementsLink to Airflow Requirements

Air is taken in from the front and blown out, across the processing blades, to the right. The image below shows the direction of airflow.

(E) ATTENTION

  • DO NOT obstruct the ventilation holes as to do so will prevent efficient cooling.
  • If the maximum operating temperature of +30°C (+86°F) is exceeded, then the power to the processing blades is cut (to prevent damage to the FPGAs due to overheating). In this instance, all operations will stop until the unit has reached a safe temperature.


 (F) ATTENTION

  • N'obstruez PAS les trous de ventilation, car cela empêcherait un refroidissement efficace.
  • Si la température maximale de fonctionnement de +30°C (+86°F) est dépassée, l'alimentation des lames de traitement est coupée (pour éviter d'endommager les FPGA en raison d'une surchauffe). Dans ce cas, toutes les opérations s'arrêteront jusqu'à ce que l'unité ait atteint une température sûre.
