SMI300XS Exam Dumps - Supermicro MI300X GPU Questions and Answers

Theair shroudis a crucial component in theSupermicro MI300X GPU system, designed todirect airflow efficientlyover high-performance GPUs and CPUs.Before removing the air shroud, two screws must be removed, and they are located on both sides of the motherboard tray.

Why are these screws important?

They secure the air shroud to the chassis, preventing unwanted movement.

Removing them ensures the air shroud can be lifted safely, without damaging cooling pathways.

They prevent vibrations from GPU cooling fans from dislodging the shroud over time.

Incorrect Answers Explained:

A (On top of the motherboard tray)→ Incorrect, as the screws are not mounted on top but on thesides of the motherboard tray.

C (On both sides of the PCIe tray)→ The PCIe tray does not secure the air shroud.

D (On both sides of the GPU tray)→ The GPU tray does not directly hold the air shroud in place.

Official Documentation Reference:

Supermicro AS-8125GS-TNMR2 Cooling System Guidestates that theair shroud is secured by two screws on both sides of the motherboard tray.

Before removing theNVMe backplanein aSupermicro MI300X GPU system,all NVMe drives must be disengaged but not fully removed.

Why is this necessary?

Ensures safe backplane removal

NVMe drives are directly connected to the backplane viaMCIO or U.2 connectors.

Keeping them engaged couldput stress on the connectors, causing damage.

Prevents accidental disconnects

Removing the drives completely isnot necessary, butdisengaging them ensures they do not obstruct removal.

Avoids power damage

If the drives remain engaged during backplane removal, they may still haveresidual power, which can causeconnector damage or electrical failure.

Why other options are incorrect?

B (Disengage PSUs)→ While power should be off,removing PSUs is not required for NVMe backplane removal.

C (Disengage fans)→ Fans are independent components anddo not interfere with the NVMe backplane.

D (Disengage the field engineer)→ Not a valid answer; field engineers are not system components.
