Keep supported HPE FlexFabric switches within their intended thermal envelope with the X722 back-to-front fan tray. Built for the JL595A platform, this replacement cooling component is designed to maintain the airflow path required by the chassis rather than forcing a generic fit. That matters in dense network closets and production racks where airflow direction is part of the system design, not an afterthought. The tray’s compact footprint helps it fit cleanly into compatible switch hardware without adding unnecessary bulk. At approximately 4.80 oz, it is a lightweight service part, yet it plays a critical role in sustaining stable operation under continuous load. For teams maintaining enterprise switching infrastructure, the value is in preserving the original cooling architecture of the platform and avoiding thermal mismatches that can shorten component life or trigger performance issues. Choose this fan tray when you need a direct-fit cooling part for select HPE FlexFabric switches and want to keep the chassis operating as designed. It is a practical, specification-matched replacement for environments where uptime depends on consistent internal airflow and predictable hardware behavior.
