Redundant 700W Server Supply
The HP 399542-B21 is a hot-plug redundant power module rated at 700W. It fits ProLiant DL360 G5 servers across Base, Entry and Performance configurations. IT teams use it to add fault-tolerant power to 1U rack systems without shutting down the host.
Thermals Noise and Power Draw
The unit accepts 100 to 240 V input and includes active power factor correction. Redundant operation shares load between modules, reducing per-unit stress and fan speed during typical workloads. Hot-swap capability allows replacement while the server remains online.
Upgrade Context
This supply replaces a failed or missing module in a DL360 G5 chassis to restore N+1 redundancy. The jump is worth it when uptime requirements exceed single-supply risk tolerance. It does not serve platforms outside the listed G5 family.

Fragen zu diesem Artikel
How do I install the HP 399542-B21 700W redundant power supply into a ProLiant DL360 G5 and what step is often missed?
Slide the unit into the hot-plug bay until the latch clicks, then verify the amber LED turns green; the step often missed is confirming both modules show green before closing the chassis.
What maintenance or replacement will the HP 399542-B21 700W redundant power supply need later?
The internal fan is the only moving part; expect to replace the module when bearing noise appears or the status LED stays amber after reseating.
What limit appears first on the HP 399542-B21 700W redundant power supply under sustained load?
The 700W maximum output is the hard ceiling; once total draw reaches that level the supply will throttle or shut down to protect the server.
