3.4 .edge - Fans and Cooling
.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 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 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.
Ordering Information
The fan tray is included in all frame variants. To order a spare part, use the part number: A00/10-55 .
The fan tray is removable and can be exchanged from the front of the frame. See Replacing the Fan Tray for
instructions.

(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.
