J9830B HPE Aruba 5400R 2750W PoE+ zl2 Power Supply Unit

The J9830B HPE Aruba 5400R 2750W PoE+ zl2 Power Supply Unit is the most powerful electrical component available for the Aruba 5400R zl2 Switch Series. Engineered for high-density enterprise deployments, this PSU is designed to support the maximum possible Power over Ethernet (PoE+) load across a fully populated chassis. It provides the foundational power necessary for large-scale Wi-Fi 6 installations, smart building automation, and high-performance IoT environments where power reliability is a non-negotiable requirement.

With a massive 2750-watt capacity, the J9830B is specifically built to eliminate power bottlenecks in the 5412R or 5406R chassis. While lower-wattage PSUs may limit the number of ports that can simultaneously deliver 30W of PoE+, a J9830B configuration allows for nearly every port to operate at full power. This makes it the ideal choice for environments deploying high-draw devices such as Class 4 PoE peripherals, pan-tilt-zoom cameras, and multi-radio wireless access points.

To achieve its full 2750W output, the J9830B operates on 200V - 240V AC high-line power circuits. This high-voltage requirement ensures maximum conversion efficiency and reduced thermal output compared to standard 110V units. The PSU features an 80 PLUS Silver equivalent efficiency rating, which significantly lowers operational costs and cooling requirements within the data center or intermediate distribution frame (IDF) closet. When connected to a 110V source, the unit will operate at a reduced capacity, so proper electrical planning is essential.

The J9830B supports advanced high-availability features inherent to the zl2 architecture. It is hot-swappable, allowing for seamless replacement or upgrades without needing to power down the switch fabric. When multiple J9830B units are installed, the switch can be configured for N+1 or N+N redundancy. This ensures that even if a power circuit or an individual PSU fails, the mission-critical network services and PoE devices remain powered and connected, providing true carrier-grade resilience.
