Build out a modular switching platform around an empty chassis rather than a pre-populated appliance. Extreme Networks 8722-32C supplies the chassis enclosure only, with no power supplies and no fan modules included. It provides the physical platform for a completed network switch configuration while leaving the power and cooling elements to be selected separately. This chassis suits network environments where the hardware configuration must be assembled around site requirements. Power and fan components are necessary considerations before the platform can be placed into service, since neither is supplied with the chassis. Separating the enclosure from those components helps support configurations where power and airflow requirements are determined as part of the overall switch build. The defining characteristic of this version is its empty-chassis shipment. Buyers needing a chassis foundation rather than a fully populated switching system can start with the enclosure and add the required compatible components for the intended installation. Verify that the selected power and cooling hardware aligns with the completed platform configuration before installation. This approach keeps the chassis selection distinct from the power and thermal hardware required for operational use.
