Whenremoving the GPU trayin anMI300X system, the following precautions must be taken:

Two people should remove the trayas itweighs over 70 pounds, making it unsafe for one person to handle.

Keeping the tray straightprevents it fromtilting, which candamage the chassis components.

Unnecessary movement can damage cooling fansdirectly beneath the GPU tray.

Since all the above precautions arecritical for safe removal, thecorrect answer is D (All of the above).

ForSupermicro MI300X GPU systems,removing the power supply unit (PSU) improperlycan lead to serious issues.

Why the red lock exists?

Thered locking mechanismensures that thePSU is properly securedin the system.

Before disengaging the PSU, thered lock must first be unlockedto avoid damage.

If you forcefully shift the release lever without unlocking the red lock:

B: The power supply unit will fail→ If the PSU is removed improperly, it can causeinternal damageto power connectors, resulting in PSUfailure or improper functioning.

C: You could permanently damage the lock on the power supply unit→ Thelocking mechanismis designed for smooth disengagement. Forcefully shifting the lever canbreak or warpthe lock, making itimpossible to secure the PSU back in place.

Incorrect Answers Explained:

A (All answers are correct)→ This is incorrect becausenot all answers are valid.

D (The PSU can no longer be secured into the tray)→ This happensonly if the lock is damaged, which is covered underoption C.

Supermicro’s official documentation clearly statesthatunlocking the red lock firstis a critical step before removing or replacing the PSU.

TheIPMI Dashboard health event loghelpsidentify component failuresusing ared severity status indicator. If a fan or power supply fails, theevent log will mark it as a red alert, allowing users to take corrective action.

Option A (Correct):Red severity status in theevent logsignals a failed component.

Option B (Incorrect):Fansdo not change colorswhen failing.

Option C (Incorrect):There is nopurple status indicatorin IPMI for failures.

Option D (Incorrect):You cannot configure a new fan inIPMI under Configuration; you must replace a failed fan.

TheAGFHC Toolis specifically designed forSupermicro’s internal employeesandauthorized resellers (VARs). These users require access to diagnostic and firmware update tools that are restricted totrained personnel.

Option A (Correct):Internal Supermicro employeesuse this tool for system maintenance and diagnostics.

Option D (Correct):VARs (Value-Added Resellers)are authorized to use the tool forcustomer support and system integration.

Option B (Incorrect):GeneralSMC partners do not have accessto AGFHC.

Option C (Incorrect):End customers do not have accessto this tool.

IfROCm commands fail to provide output, the primary issue is likelymissing or undetected GPUs. Thebest way to validate this is by checking the IPMI GUI and reviewing the GPU component sectionto ensure that all GPUs are present.

Option A (Correct):Missing GPUsare the most common causeof ROCm failures. The IPMI GUI provides visibility into which GPUs are detected.

Option B (Incorrect):CPU misalignment would causegeneral system failure, not ROCm-specific issues.

Option C (Incorrect):The GPU baseboard status can be checked in IPMI but isnot the primary causeof ROCm failures.

Option D (Incorrect):ROCm can function with multiple missing GPUs, butthe key issue is confirming GPU presence first.

This question is a duplicate ofQuestion No. 20. The correctWindows executable file extension for SUM is .exe.

Option A (Correct):SUM on Windows is executed using .exe.

Option B (Incorrect):.sh is a script file format for Linux, not Windows.

Option C (Incorrect):.txt files contain textand cannot execute commands.

Option D (Incorrect):"binary" is not a valid file extension for SUM execution on Windows.
