HP 1000W Redundant Power Supply

The HP 399771-B21 is a 1000W redundant server power supply designed for 220V operation. It serves as a direct replacement unit for HP ProLiant ML350 G5, ML370 G5 and ML380 G5 servers. The redundant design allows continued operation if one module fails.

Replaces Failed or Missing Modules

This supply replaces a failed or missing hot-plug module in the supported G5 chassis to restore N+1 redundancy. The jump is worth it when the server currently runs on a single unit or shows alerts for a degraded power subsystem. It is not for buyers who need a higher wattage rating or a different input voltage.

Hot-Plug Installation

Installation uses the server’s hot-plug bay so the system stays online during the swap. The module slides in and locks with the integrated latch. What usually goes wrong is inserting the unit at an angle, which prevents the connector from seating fully and leaves the redundancy alarm active.
