Maintain network uptime in DC-powered locations with the Aruba 4000i POE 240W DC-DC DIN power supply. Designed for HPE Aruba 4100i deployments, it accepts 12 to 48 V DC input and delivers 240 W of output, giving edge switches the power budget they need for PoE-connected devices in industrial cabinets, remote closets, and transport or utility environments. The DIN-rail format is a practical advantage in control panels and compact enclosures where rack power is not the right fit. By converting DC input directly for the switch platform, this supply helps simplify deployment in locations that already run on battery-backed or plant DC infrastructure. That makes it a better choice than generic adapters when the installation needs predictable mounting, cleaner integration, and support for network hardware built for edge use. For procurement teams, the value is straightforward: this is a purpose-built power supply for a specific Aruba platform, not a general-purpose accessory. That specificity matters when uptime, fit, and electrical compatibility are part of the purchase decision.
