Keep critical switching infrastructure powered through maintenance windows and unexpected events with the Juniper QFX5220-32CD DC PSU AO,DC CABLE. Built for the QFX5220-32CD platform, this 1,600 W power supply supports direct-current environments where predictable power distribution and rack-level efficiency matter. Hot-swap capability helps teams replace a failed unit without taking the chassis offline, reducing operational risk in production networks. The DC cable-ready design simplifies integration in facilities already standardized on DC power architecture, making it a practical fit for high-density switching deployments where uptime and service continuity are non-negotiable. This power supply is a strong choice for organizations that need platform-specific fitment rather than a generic replacement. Matching the correct PSU to the switch model helps preserve compatibility, simplify spares planning, and support the reliability expectations of enterprise network operations. For teams managing critical east-west traffic, aggregation layers, or data center access switching, the right power module is part of the resilience strategy—not an afterthought.
