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. The fan module may be labeled Air Out.
If the power supply module has a blue tab, the airflow is back-to-front. The fan module may be labeled Air In.

The following 800 W AC or DC internal power supply units (PSUs) are available for the switch:

Part numbers XN-ACPWR-800W-F and XN-DCPWR-800W-F provide front-to-back airflow for cooling and 800 W AC or DC power, respectively.
Part numbers XN-DCPWR-800W-F and XN-DCPWR-800W-R provide back-to-front airflow for cooling, and 800 W AC or DC power respectively.
