HP Aruba X371 250W Proprietary Power Module

The HP Aruba X371 is a proprietary 250 watt power module designed for compatible Aruba network switches. It delivers 12 V DC output to support switch operation in enterprise environments. This new unit carries part number JL085A and serves as a direct replacement or spare for supported hardware. It is not intended for standard ATX desktop builds or generic server chassis.

120-230 V AC Input with 12 V DC Output

The supply accepts 120 V AC or 230 V AC mains input and converts it to a 12 V DC rail rated at 250 W. Normal operating thermals and acoustic levels are governed by the host switch chassis and its integrated cooling design. Power draw scales with the connected switch load up to the 250 W maximum. Builders needing redundant or higher-capacity modules should verify compatibility with their specific switch model.

Questions about this item

How do I install the JL085A power supply into an Aruba X371 switch, and which step is often missed?

Slide the module into the chassis until the latch clicks, then tighten the captive screws to secure it; the step often missed is fully tightening those screws so the unit seats properly on the 12 V DC bus.

What maintenance will the JL085A power supply need during its service life?

Clean the intake vents periodically to prevent dust build-up on the internal fan, and replace the unit if the front LED shows a fault or the switch logs a 12 V DC rail failure.
