HPE Aruba Non-Instant JW657A PSU-350-AC 350W AC power supply

Aruba JW657A 350 W AC power supply

This HPE Aruba JW657A unit delivers 350 W of AC power for compatible Aruba network equipment. It is intended for administrators who need a direct replacement or spare supply for supported switches and controllers. The black enclosure matches the standard Aruba form factor used in rack and desktop deployments.

350 W capacity with standard AC input

The supply provides 350 W of continuous output from a regular AC mains connection. It comfortably powers a single supported Aruba device under typical load. Headroom diminishes if the connected hardware draws sustained peak current or if multiple modules share the same circuit without dedicated feeds.

Fits Aruba Non-Instant chassis

The module slides into the power-supply bay of Aruba Non-Instant chassis models that accept the JW657A form factor. No additional rails or adapters are required beyond the standard AC cord. Using this supply frees the second bay for redundancy or leaves it open for future expansion in single-supply configurations.
