⚙️ Fit Notes

• Verify your existing power supply family and connector before ordering, as not all G5 servers use this same module.
• This power supply family is used in supported DL380 G5, DL385 G5, ML350 G5, and ML370 G5 platforms, but it is not the correct replacement family for every ProLiant G5 server.
• 399771-B21 typically refers to the IEC cord kit version, while 399771-001 refers to the NEMA cord kit version.
• 403781-001 is the common spare reference associated with this power supply family.
• Full 1000W output requires high-line AC input. Systems running on lower-voltage input may have reduced available output.
• Sold as an individual power supply module. Systems configured for redundancy typically use two installed units.
