Product Identity

The HP JG544A is a hot-plug, redundant power supply module designed for the 5500-24G-PoE+-4SFP HI and 5500-48G-PoE+-4SFP HI switches, each equipped with two interface slots. It delivers the electrical input required to run the switching fabric and Power over Ethernet ports. Network engineers and infrastructure teams install it to keep core aggregation layers powered.

Fit and Exclusions

This module suits administrators maintaining the specified 5500 HI PoE+ models where a plug-in, redundant supply is required. It does not suit buyers who need a power supply for non-PoE 5500 variants, for switches outside the 5500 HI family, or for chassis that accept only fixed internal units. Operators requiring AC and DC input options in a single module should look elsewhere.

Build Integration

The supply slides into an available power-supply bay on the target switch, drawing cooling from the system fans and sharing load with a second module for redundancy. Its hot-plug design allows replacement without powering down the switch, preserving uptime for connected PoE devices. The unit frees the builder from scheduling maintenance windows for power-module swaps.

  • Plug-in module installs without tools or cabling
  • Purpose-built for 5500-24G and 5500-48G PoE+ switches
