HPE Aruba X371 250W redundant power supply

The HPE Aruba X371 is a 250 Watt hot-plug power supply designed for redundant operation in compatible Aruba switches. It accepts AC input from 100 to 240 Volts and delivers a 12 Volt DC output. This unit targets network administrators who need resilient power for supported HPE Aruba 2930M and 3810M series switches.

Hot-plug redundancy keeps the switch running

The hot-plug design allows a failed module to be swapped without powering down the switch, maintaining network uptime. Redundant pairing means a second supply takes the load instantly if one unit fails. This capability changes maintenance windows from emergency outages to scheduled, non-disruptive events.

250 Watt output at 12 Volts DC decides compatibility

The supply provides exactly 250 Watts at 12 Volts DC, matching the power budget of the listed 2930M and 3810M models. Buyers whose switches require a higher wattage or a different output voltage cannot use this module. Verify the switch model against the supported list before ordering.

Questions about this item

Does the 250 W hot-plug unit require any scheduled fan or capacitor replacement?

No scheduled fan or capacitor replacement is documented; the module is designed for continuous operation inside the listed switches.

What is the first limit reached when the supply runs at full 250 W output for extended periods?

The 250 W output rating itself is the limiting factor; sustained loads above that level will trigger protection.

How much heat and noise does the X371 produce when powering a 48-port switch all day?

The supply exhausts waste heat through its internal fan; acoustic and thermal output match the host switch’s published environmental specs.
