Do Not Install Components with Different Airflow or Wattage in the Switch
Do not mix power supplies with different airflow. If the power supplies are color-coded,
ensure they are either all azureblue for airflowin modelsor all gold for airflow out models.
If the power supplies are not color-coded but have a label, ensure that the chassis is
either using all airflow in ( AFI ) or all airflow out (AFO). Likewise, ensure that all fan
modules have the same airflow and match the airflow of the power supplies. Fan modules
are also either color-coded azure blue for airflow in or gold for airflow out. If the fan
module has a label instead of being color-coded, ensure that labels (AIR IN and AIR OUT
) are not mixed. If the fan modules have AIR IN labels, the power supplies must also have
AIR IN labels; if the fan modules have AIR OUT labels, the power supplies must also have
AIR OUT labels.
