Power Capacity and Form Factor

The HPE JW657A is a 350 Watt AC power supply designed as a plug-in module for compatible HPE Aruba network equipment. It delivers 350 W of output power and supports hot-plug redundant operation so a failed unit can be replaced without shutting down the device. The module accepts a wide input range of 100 to 240 V AC. It is supplied new in black finish.

Compatibility and Physical Checks

Verify that the target switch or appliance lists the JW657A as a supported power supply before ordering. Confirm the chassis has an available plug-in module bay and that the hot-plug redundant feature is supported by the host system. Ensure the rack or cabinet provides sufficient clearance for the 17.500 length dimension. Check that the site power infrastructure can deliver 100 to 240 V AC to the unit.

Ideal Use Cases and Limitations

This supply suits network administrators adding or replacing a hot-plug redundant 350 W module in qualified HPE Aruba hardware. It is not intended for desktop PCs, workstations or servers that use standard ATX or EPS form factors. Buyers who need a different wattage, a non-redundant design or a power supply for non-Aruba equipment should look at other products.

Questions about this item

Does the JW657A 350W AC power supply ship with any mounting brackets or power cords included?

The unit is a plug-in module designed for hot-plug redundant bays; mounting rails and AC power cords are sold separately.

Should I choose the 350W model or look for a higher-wattage version for my Aruba switch?

Select the 350W model when your switch chassis lists 350W as the supported redundant power supply; higher-wattage units have different part numbers and may not fit the same bay.

What does the 350W rating mean once the supply is installed in a live switch?

It delivers up to 350 watts of DC power to the chassis while accepting 100-240V AC input, enabling hot-swap replacement without downtime.
