Keep critical network infrastructure powered with the Extreme Networks 715 W AC PSU FB. This AC power supply module is designed for Summit X465, VSP4900, 5520, and 5720 systems, giving you the power headroom needed for PoE-enabled switching and dense enterprise deployments. Front-to-back airflow supports rack-level thermal design, which matters when switches are stacked into high-density closets or production network rows. For teams standardizing on Extreme Networks hardware, this module helps preserve service continuity without forcing a platform change. It is the right fit when you need a replacement or spare that matches the original power and airflow profile of the chassis. That reduces risk during maintenance windows and keeps procurement aligned with the installed base. Choose this PSU when uptime, thermal consistency, and platform compatibility matter more than a generic replacement. It is built for environments where a power module is not just a component, but part of the network’s operating margin.
