DELL HP-U478FC5 Redundant Power Supply for PowerVault MD1000 MD3000

Compatible Storage Arrays

This redundant power supply is built for Dell PowerVault MD1000 and MD3000 direct-attached storage enclosures. It replaces a failed unit or adds a second module to complete the redundant pair. The part number HP-U478FC5 identifies the exact module required by those arrays.

Hot-Swap Integration

The supply slides into the rear bay of the supported PowerVault chassis without tools or cabling changes. Its hot-swap design lets you exchange a module while the enclosure stays powered and the drives remain online. Redundant operation is restored as soon as the replacement seats and reports ready.

Targeted Replacement Part

This module suits administrators maintaining a Dell PowerVault MD1000 or MD3000 who need a genuine redundant power supply. It does not fit other Dell enclosures, third-party JBODs, or standard server chassis. Buyers needing a different wattage, form factor, or compatibility list should look at other power-supply models.
