1000 W 54 V DC Hot-Plug Power Supply

This HP J9580A X312 unit delivers 1000 W of 54 V DC power from a 100-240 V AC source. It uses a proprietary form factor designed for direct installation inside compatible HP network switches. The module supports hot-plug replacement for continuous operation.

Network Switch Deployments Requiring Redundant Power

This supply suits administrators running HP 3800-24G-PoE+-2XG or 3800-48G-PoE+-4XG switches that need redundant or hot-swappable 1000 W capacity. It is not suitable for standard ATX chassis, servers needing 12 V output, or builds requiring industry-standard pinouts.

Proprietary 54 V DC Output Voltage

The defining specification is the 54 V DC output, which only matches the input requirements of the specific 3800-series PoE+ switches listed. Verify the switch model before purchase because the proprietary connector and voltage prevent use in any other equipment.

Questions about this item

How do I install the J9580A into an HP 3800-48G-PoE+-4XG switch and what step is often missed?

Slide the module into the power supply bay until the latch clicks, then verify the green LED lights to confirm the 54 VDC output is active.

What maintenance will the J9580A need after extended operation in a 3800-24G-PoE+-2XG switch?

Clean the intake vents quarterly to prevent dust buildup; the internal fan is not user-serviceable so replace the entire unit if airflow drops or the fault LED turns amber.

At what point does the 1000 W limit of the J9580A become the bottleneck under sustained PoE+ load?

When the combined draw of all 48 PoE+ ports approaches 1000 W, the supply will current-limit and the switch may disable lower-priority ports to stay within the 54 VDC budget.
