90W 54V 1.67A 4-Pin AC Adapter Model PA-1900-2P-LF, OEM PN 5066-2164, Compatible with HPE 2530 8G PoE Switch J9774A J9982A, Aruba 2930F 8G 2SFP Network Switch Power Supply Charger

This 90W external PoE switch power adapter is a fully compatible substitute for original HPE PA-1900-2P-LF power unit, matching official spare part number 5066-2164, interchangeable with PA-1900-2P2 and 5066-5569 power adapters. It is specially engineered for HPE / Aruba gigabit PoE network switches, including HPE 2530 8G PoE Switch J9774A, OfficeConnect 1820 8G PoE J9982A and Aruba 2930F 8G 2SFP switch models. Rated 54V 1.67A 90W output precisely satisfies the maximum 86W power consumption demand of J9774A 8-port PoE+ switch, ensuring all PoE ports run at full load simultaneously without power attenuation.

Equipped with a dedicated lockable 4-pin DC plug, it locks firmly into the rear power port of target switches to avoid accidental disconnection in server racks. The internal intelligent power management chip maintains stable 54V regulated voltage under variable PoE load fluctuations, fully compliant with IEEE 802.3 at PoE+ standard to power surveillance cameras, enterprise wireless access points and IP desk phones reliably. 100240V full-range AC input adapts to all regional mains power grids without extra voltage converters. Built-in comprehensive safety protection instantly shuts down output once overload, short circuit or excessive internal temperature occurs, protecting critical network switch hardware from permanent burnout.

Adopting lead-free LF circuit design in line with RoHS environmental standards, the rectangular ribbed black casing optimizes passive heat dissipation for continuous round-the-clock rack operation. Every adapter passes strict full-load aging, ripple and startup testing before shipment. Multiple regional AC input cords (US / EU / UK / AU) are optional to fit different country cabinet socket standards.
