Redundant 720 W AC power supply

The HP JG544A#ABA is a 720 W hot-plug redundant AC power supply designed for compatible HP networking equipment that requires 56 V DC PoE power. It accepts a wide 90 V to 264 V AC input range at 50/60 Hz frequency.

Plug-in module installation

This unit uses a plug-in module form factor that slides into a supported chassis bay for tool-free installation. Hot-plug capability allows replacement without powering down the system. The module only functions inside a compatible HP chassis and cannot operate as a standalone desktop adapter.

Questions about this item

How do I confirm the HP JG544A#ABA 720W supply is operating correctly after installation?

Verify the unit powers on and delivers a steady 56 V output to the connected switch, then check the management interface shows both redundant modules active and sharing load within the 720 W rating.

What ships with the HP JG544A#ABA and what must I purchase separately?

The box contains the 720 W plug-in power supply module only; an AC power cord rated for 90–264 V AC and the compatible switch chassis are sold separately.

Which input-voltage version of the JG544A#ABA should I choose for a 220 V AC mains supply?

This single model accepts 90–264 V AC at 50/60 Hz, so it works on 110 V, 220 V or 240 V mains without any version selection.
