HP 194989-002 Redundant Power Supply
This 400 W redundant power supply is built for the HP ProLiant DL380 Generation 3 server. It accepts 240 V AC input and delivers continuous output power for enterprise workloads. The module is designed for hot-swap replacement in a redundant pair. It targets IT teams maintaining legacy rack-mounted infrastructure.
Sustained load behaviour
Redundant architecture shares current between two units so each runs well below its 400 W limit during normal operation. This reduces thermal stress and extends component life under 24-hour duty cycles. Load balancing is handled by the server backplane without external management software. Efficiency remains stable because neither module approaches peak capacity.
Installation and common issues
The supply slides into the dedicated bay and locks with a thumbscrew; no cables are routed by hand. Compatibility is limited to the ProLiant DL380 G3 chassis, so it will not fit other server models. A single-module configuration leaves the system without redundancy. Firmware mismatches between paired units can prevent the server from posting.

Questions about this item
How loud or hot does the 400 W redundant supply get when the ProLiant DL380 G3 runs continuously?
The unit is a hot-plug redundant module designed for the DL380 G3 chassis; its own fans draw cooling air through the server, so noise and heat follow the system fan profile rather than a standalone rating.
What must already be in the rack for this 194989-002 module to deliver power to the server?
A ProLiant DL380 Generation 3 chassis with an empty redundant power-supply bay and a 240 V AC feed to the rack PDU or wall outlet.
Will the supply work alongside the original power module already installed in my DL380 G3?
Yes — it is built as a matching redundant unit for the DL380 G3, so a second 400 W module slides into the adjacent bay and shares the load with the existing one.
