Sustain critical switching capacity with a 1,100 W AC power supply module engineered for enterprise Summit deployments. Front-to-back airflow supports rack-level thermal design, helping preserve predictable cooling paths in environments where switch placement and airflow direction matter. This module is built for Summit X465, X450G2, X460G2, and VSP4900 systems, making it a practical fit for infrastructure teams standardizing on compatible Extreme Networks hardware. For production networks, power supply selection is not a commodity decision. Matching wattage and airflow to the chassis helps maintain operational stability, simplify spare planning, and reduce the risk of thermal mismatch in dense racks. This PSU is suited to teams that need a replacement or expansion component aligned to the original platform design, rather than a generic substitute. When uptime, serviceability, and rack consistency matter, the right power module protects the investment already made in the switching layer.
