HP Redundant Power Supply

This HP 408947-001 is an internal redundant power supply designed for specific HP workstations. It provides backup power capability to maintain system operation if a primary unit fails. The unit suits IT professionals managing compatible workstation fleets. It installs directly into the chassis of supported models.

Redundancy for Continuous Uptime

The redundant design allows the workstation to continue running during a power module failure. This capability reduces the risk of unexpected shutdowns and data loss for critical workloads. No additional software or accessories are included with the unit. The hardware change alone adds the failover function.

Suits xw6400 xw8400 xw9400 xw6600 Owners

This supply fits the HP xw6400, xw8400, xw9400 and xw6600 workstations only. Builders using different chassis or brands must look elsewhere. Buyers needing higher wattage than the original specification cannot use this part. It is a direct replacement for the listed models.

Questions about this item

Will the internal fan in the 408947-001 need replacement after long-term use?

The redundant design lets you swap one supply while the other keeps the workstation running, so a fan failure only requires replacing that module.

What thermal limit appears first when the supply runs continuously in an xw9400?

Each module shares the load, keeping individual temperatures lower than a single-unit supply under the same sustained draw.

How much extra heat and noise does the redundant pair add to a fully loaded xw8400?

Two supplies spread the power conversion across both units, reducing peak fan speed and case temperature compared with one supply at full load.
