Site Selection
The following criteria should be considered when selecting a site to install the switch:
•
Temperature and Ventilation: For proper ventilation, install the switch where there is ample airflow
to the front and back of the switch. The ambient temperature should not go below 0° or exceed
40°C.
Note:
To prevent the switch from overheating, do not operate it in an area where the ambient
temperature exceeds 40°C (104°F).
Pour empêcher l’interrupteur de surchauffe, ne pas utiliser il dans une zone où la
température ambiante est supérieure à 40°C (104°F).
•
Airflow Orientation:
The fans and PSUs determine the airflow direction through the switch. The color of the visible
handles or labels indicate the airflow direction.
Note: The figures shown use representative Arista switches to illustrate airflow directions.
Refer to rear panel to determine the airflow for your switch.
•
Blue Handle: Air Inlet module. The following figure shows the airflow through the switch with air
inlet modules:

Red Handle: Air Exit module. The following figure shows the airflow through the switch with air
exit modules:
