NVMe SMBus Headers

NVMe SMBus (I

C) headers (JNVI2C), 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.

Chassis Intrusion

A Chassis Intrusion header is located at JL1 on the motherboard. Attach the appropriate cable

from the chassis to inform you of a chassis intrusion when the chassis is opened. Refer to

the table below for pin definitions.

Note: Chassis intrusion is not supported on SYS-730A-I.

Speaker Header (Optional for an External Speaker/Buzzer)

A speaker header, located at JD1, can be used in conjunction with an external speaker

(optional). Use an appropriate cable to connect this header to an external speaker or buzzer

for support of BIOS beep codes and system alarms. See the layout below for JD1 location.
