2-22 External Connectors
24V USB+ Power Port
The 24V Powered USB port is capable of supplying 24V at 0.5A continuous and 3.0A
peak.
• Color — Red (Pantone 032C)
• Connector — Foxconn P/N UB11123-GHR3-4F or FCI 55917-601LF
The 24V is fused with a socketed fuse. An overcurrent signal is used to detect when this
fuse is open. This signal is connected to a GPIO on the Super I/O.
• Fuse — Tyco REUF250U or NCR approved equivalent. A separate return line, 24V_
RET, is used instead of ground to provide noise isolation.
