● AC or DC power supply with airflow from the PSU side to the I/O side—Reverse
CAUTION: Switches with fan airflow from the PSU to the I/O—reverse airflow—are subject to tighter
restrictions for power consumption on cables and optics that are used for 400 GbE ports. Reverse airflow
switches do not support high-power cables or optics. 400 GbE transceivers and active cables may exceed
the supported threshold. For more information, see the
High-Power Optics for SmartFabric OS10 Dell EMC

.
CAUTION: Review the optics specification sheet and the switch data sheet to understand which models support
airflow from the I/O to the PSU (normal) and which support airflow from the PSU to I/O (reverse).

The switch has a pull-out tag, which is known as a luggage tag, on the I/O-side of the switch. The front of the luggage tag
includes switch ID information. The back of the luggage tag includes a QRL that takes you to a How-To site where you can
