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.

Themidplane lid removal processis designed to betool-freeand follows aspecific sequence to avoid damage.

Thecorrect methodis:

Push in on the two handleslocated near thePCIe tray.

Slowly lift the midplane lid up, ensuring it does not catch on other components.

Remove the lid at an angleto avoid damaging adjacent connectors.

Why this method is used?

Theangled removalhelpsavoid contact with fragile connectorson the midplane.

Forcing the lid straight upcould damage PCIe slots or motherboard connectors.

Official Documentation Reference:

Supermicro AS-8125GS-TNMR2 Disassembly Manualdetails thecorrect method for removing the midplane lid.

When reinstalling theNVMe backplane, several critical cables must be properlyreconnectedto ensure the system functions correctly.

Required Connections:

SATA Cable→ Some NVMe backplanesalso support SATA drives, requiring SATA connectivity.

Power Cables→ The NVMe backplanerequires direct powerto enable SSD operations.

MCIO Cables→ These cables providehigh-speed data connectivitybetween the NVMe drives and the motherboard.

54-Volt Power Cable→ Thissupplies direct powerto the NVMe backplane foroptimal performance and stability.

Why other options are incorrect?

B (Only SATA cable)→ NVMe backplanes usePCIe-based storage. While SATA connectionsmayexist,they are not the only required cables.

C (Only MCIO cables)→ While MCIO cables are necessary for PCIe-based NVMe drives,power cables must also be reconnectedfor the system to function.

D (Only power cables)→Data communication would failwithout MCIO connections, rendering the systemunable to detect NVMe drives.
