Move traffic through a data center Ethernet fabric while matching a DC-powered rack design. Extreme Networks 8722-32C-DC-F combines the 8722 switching platform with a DC power-supply configuration and front-to-back fan airflow. This airflow direction carries air through the chassis from the rack front toward the rear, aligning the switch with cabinets built around a front-to-rear cooling path. The power and airflow configuration matters when a switch must fit an established rack architecture rather than require changes to cabinet power or thermal layout. DC power supports environments standardized on DC distribution, while front-to-back fans suit rows where cool air enters at the front and exhaust air is managed at the rear. Selecting the correct airflow orientation helps prevent a chassis from working against the direction used by adjacent equipment. This 8722 configuration is distinguished by the combination of DC power and front-to-back fans in the same hardware build. Verify that the rack provides the required DC power arrangement and that its cooling design expects front-to-rear chassis airflow. The switch belongs in data center locations where power provisioning, fan direction, and cabinet exhaust planning must remain consistent across the installed network infrastructure.
