Key Features

• Stable 12V DC, 1.25A regulated output
• Correct small-pin barrel connector for precise fit
• OEM-level replacement for Delta / HP power supplies
• Cross-referenced to multiple part numbers for easier sourcing

Fit Notes

• If your original brick label shows 5188-6700 or 5066-1122, this adapter is a direct one-for-one replacement.
• Connector is the 5.5 mm × 3.0 mm barrel with center pin (sometimes described as “small-pin”) used on these desktop switches.
• Some models (16-port or 24-port versions) may have internal power supplies instead. Check the rear panel: if it has an IEC power inlet, no external adapter is required.
