Install Internal Power Supplies
If your device does not come with an installed internal power supply, you can install one
or two power supplies. All installed power supplies must have the same airflow direction
(front-to-back or back-to-front) and must also match the airflow direction of the fan
modules.
- If the power supply module has a red tab, the airflow is front-to-back.
- If the power supply module has a blue tab, the airflow is back-to-front.
