The Hewlett Packard Enterprise J9830A Power Supply is a 2750W PoE+ plug-in module designed for the Aruba 5400R zl2 series switches, delivering robust power for high-density PoE deployments such as access points, IP phones, and cameras. As a hot-swappable, dual-PSU capable module, it accepts 100–240 VAC input at 50/60 Hz, features integrated fan cooling, and mounts in a switch chassis rear slot to support redundant, enterprise PoE infrastructure. This unit is compatible with Aruba 5406R zl2 and 5412R zl2, carries MPN J9830B / J9830A, and, while end-of-life, remains widely available new or refurb, with common replacements including JL085A.
