Keep the Aruba 3810 switch powered with a redundant supply designed for network continuity. The HPE Aruba X371 delivers 250 W of output power, converting 100-240 VAC input to 12 VDC output for the switch platform it was built to support. In environments where access-layer uptime matters, this supply helps preserve service during a primary PSU failure and supports the operational discipline expected in enterprise switching deployments. Its compact chassis footprint fits the switch architecture cleanly, while the modular design supports straightforward replacement in the field. At approximately 1.52 lb, it adds minimal weight to the system without compromising the power budget required for stable operation. For teams standardizing on Aruba 3810 infrastructure, this PSU is the right fit when you need a replacement or spare that matches the platform’s electrical and mechanical requirements. Choose this model when downtime is more expensive than the hardware itself. It is purpose-built for the Aruba 3810 Switch, which means fewer compatibility questions and a cleaner procurement decision than generic alternatives.
