Free Supermicro SMI300XS Practice Exam with Questions & Answers | Set: 2

When servicing theSupermicro MI300X GPU system, there are3 screwssecuring thebracket at the bottom of the motherboard trayin front of the backplane.

Purpose of these screws:

They secure the backplane’s structural integrityto prevent vibration-related failures.

Loosening them allows the removal or replacement of backplane componentssafely.

They prevent accidental disconnectionscaused by handling or system movement.

Why other options are incorrect?

A (13 screws)→ This number istoo highfor just the bottom bracket.

B (21 screws) & C (30 screws)→ These numbersapply to entire system disassembly, not just the bottom bracket.

Official Documentation Reference:

Supermicro AS-8125GS-TNMR2 Disassembly Guidespecifies thatonly 3 screwsneed to be loosened to access thebottom bracket securing the backplane.

When working withSupermicro MI300X GPU systems, it ishighly recommendedtomap or take a pictureof cable connections before disconnection.

Reasons:

Ensuring Proper Reconnection→ NVMe backplanes have multiplecritical connections(MCIO cables, power cables, data lanes, and SAS connections). Misplacing any of these cables could cause:

Boot failures

Drive detection issues

Performance degradation

Avoiding Errors in Cable Routing→ Supermicro documentation states thatimproperly routed cables can obstruct airflow, potentially leading tooverheatingin high-performance systems.

Easing Future Troubleshooting→ If issues arise after reassembly, aphoto or cable mapallows engineers toquickly verifywhether cables werereconnected properly.

This best practice isofficially recommendedinSupermicro’s service and installation guidelinesfor NVMe backplanes.
