NVMe SMBus Headers
NVMe SMBus (I
2
C) headers (JNVI
2
C1/2), used for PCIe SMBus clock and data connections,
provide hot-plug support via a dedicated SMBus interface. This feature is only available for a
Supermicro complete system with an SMCI-proprietary NVMe add-on card and cable installed.
See the table below for pin definitions.
NVMe Connectors
Use the two NVMe connectors (JNVME1 and JNVME2) to attach high-speed PCIe storage
devices.
Note
: When installing an NVMe device on a motherboard, please be sure to connect
the first NVMe port first (JNVME1) for your system to work properly.
