Which cables need to be reconnected after installing the NVMe backplane?

NVMe Backplane Connection Requirements in Supermicro MI300X Systems

Afterinstalling the NVMe backplane, the following cablesmust be reconnectedfor proper system functionality:

i2C Cable(Inter-Integrated Circuit Cable)

Responsible fordata communication, sensor monitoring, and system management functions.

Ensures thatstorage devices are properly detectedby the motherboard.

SAS Cable(Serial Attached SCSI)

Used forhigh-speed storage connectivityin hybrid NVMe/SAS systems.

Ensuresdata integrity and fast data transfers between SSDs and the system controller.

Power Cable

Supplies power to the NVMe backplaneandconnected drives.

Without this,NVMe drives will not receive power and will not be detected by the system.

Why Other Options Are Incorrect?

B (Only the SAS Cable)→ While the SAS cable is important,the power cable and i2C cable are also required.

C (Only the i2C Cable)→ The i2C cable isnot sufficient by itself; the NVMe backplaneneeds both power and data connections.

D (Only the Power Cable)→ Power is needed, butdata connectivity through SAS and i2C is essential for full functionality.

Official Documentation Reference:

Supermicro NVMe Storage System Guideconfirms thati2C, SAS, and power cables must all be reconnected after NVMe backplane installation.
