Ruckus Networks 400W AC Exhaust Airflow Power Supply | ICX 7550

Keep ICX 7550 switching infrastructure running with a 400 W AC exhaust airflow power supply designed for rack-based network environments. The RPS21-E is a purpose-built replacement and support component for no-PoE configurations, giving infrastructure teams a practical way to maintain service continuity without replacing the full switch. For enterprise networks, the value of a matched power supply is not just wattage. It is compatibility, airflow direction, and predictable integration into an installed base. This unit is rack-mountable, supports 1U deployment, and is intended for managed switching environments where uptime, thermal alignment, and clean serviceability are part of the design standard. Compared with generic alternatives, a model-specific power supply reduces risk during maintenance windows and helps preserve the operational profile of the platform. It is a sensible choice for spare inventory, repair operations, and lifecycle support where keeping the network stable is the priority.
