Pass the Supermicro MI300X GPU SMI300XE Questions and answers with CertsForce

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.

TheROCm System Management Interface (rocm-smi)is the recommended tool forgathering AMD GPU informationfrom the server.

Option D (Correct):

sudo rocm-smi -a displaysall available GPU information.

sudo rocm-smi showsbasic GPU stats.

Option A (Incorrect):These arenot valid ROCm commands.

Option B (Incorrect):"rockm-smc" and "rockm-bug.report.txt"do not exist in ROCm.

Option C (Incorrect):"rocm-gpu" and "rocm-baseboardgpu" arenot standard AMD diagnostic commands.

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.

Theevent logis the primary source of information for identifyingsystem issues and their exact timing. TheIPMI event logrecords all critical system alerts, includinghardware failures, temperature warnings, power issues, and other critical errors.

Option A (Incorrect):GPU memory specifications do not provide issue tracking information.

Option B (Correct):Theevent log tracks all system events and errors, making it essential for troubleshooting.

Option C (Incorrect):Subnet masks relate to network configurations and do not provide system issue tracking.

Option D (Incorrect):Last login attempts show security logs but arenot related to hardware or system issues.

Supermicro ships systems with aunique BMC passwordfor security purposes. Thispassword is printed on a label located on the bottom side of the system cover.

Option A (on the I/O module tag)is incorrect as the tag typically containsnetwork interface informationrather than credentials.

Option B (using the system model number as a password)is incorrect because Supermicrodoes not use default passwords based on the model number.

Option C (on the bottom of the system)is close but not precise;the correct location is the bottom side of the system cover.

Option D (label on the bottom side of the system cover)is correct, as stated in theSupermicro IPMI and BMC login documentation​.

Security Recommendation:Upon first login,Supermicro strongly recommends changing the default BMC password immediatelyfor security reasons​.

When theGPU tray is pulled out partially, itlocks in placetoprevent accidental removal or dropping. To fully remove it,two people must press down on the lever on each sidebefore continuing.

Option A (Correct):Thetray locks automaticallyto ensure safe removal, and two people are needed to press the unlock levers.

Option B (Incorrect):Thetray does not vibrate or flash redwhen released.

Option C (Incorrect):Thetray does not contain liquid components.

Option D (Incorrect):Thetray does not generate excessive heat upon removal.

TheSUM (Supermicro Update Manager) commandhas differentsyntax and optionsbetweenWindows and Linuxversions.

OnWindows, the SUM command uses .exe files and standard Windows CLI syntax.

OnLinux, SUM commands use native Linux paths, shell scripting, and different argument formatting.

For example:

Windows:sum.exe -i 10.1.1.100 -p ADMIN -u ADMIN -c checkbasicinfo

Linux:./sum -i 10.1.1.100 -p ADMIN -u ADMIN -c checkbasicinfo

Since syntax differs,the correct answer is True.

When removing theGPU tray, it is crucial tokeep it leveltoprevent damage to the chassis and cooling fans below.

Option A (Correct):If the tray tilts, it canhit the upper chassis or damage fans below.

Option B (Incorrect):There isno specific 16-degree angle requirement.

Option C (Incorrect):Work surface placement does not impact removal safety.

Option D (Incorrect):Thescrews must be removed first, but they do not affect the removal angle.

Tosafely remove the GPU trayfrom theMI300X system,two peopleare required.

Option A (Incorrect):One personcannot safely removethe tray as it is too heavy (~70 lbs).

Option B (Incorrect):Six people are unnecessary for this task.

Option C (Correct):Two peoplearerecommended by Supermicroto ensure safe removal.

Option D (Incorrect):Ten people are excessive and impractical.

Thus,the correct answer is C (2 people).
