NVMe SMBus Header

An NVMe SMBus (I²C) header is located at JNVI²C1 on the X14SBI-TF motherboard. It is used for PCIe SMBus clock and data connections, and provides hot-plug support through a dedicated SMBus interface. This feature is only available for a Supermicro complete system with a Supermicro proprietary NVMe add-on card and a proper cable installed.

For a detailed diagram of the X14SBI-TF motherboard, see the layout under Motherboard Quick Reference.
