HP J9830B 2.75 kW server power supply

2.75 kW Aruba Power Module

The HP J9830B is a 2.75 kW power module built for Aruba networking equipment. It supplies 2750 W of output power to keep switches and chassis running in data-centre environments. The unit is designed for hot-swap installation in compatible HPE Aruba platforms. It targets administrators who need redundant, high-density power for mission-critical network infrastructure.

Capacity and headroom at 2750 W

At 2750 W the module comfortably handles fully populated Aruba chassis with multiple line cards and PoE+ budgets. Headroom remains tight when every slot draws maximum load, so planning for N+1 redundancy is advisable. The supply runs out of capacity if the combined draw exceeds the rated output, triggering protective shutdown. Accurate load calculation per chassis model prevents unexpected power events.

Integration into a rack build

The module slides into the dedicated power bay of supported Aruba switches without cables or adapters. It frees up rack space by eliminating external power bricks and reduces cable clutter in dense cabinets. Hot-swap capability means a failed unit can be replaced while the chassis stays online. Compatibility is limited to the specific Aruba platforms listed in the HPE hardware matrix.
