SMI300XS Dumps With Exact Questions and Answers

Why Must the Support Bar Be Removed First?

Thesupport baris areinforcement structureinside the chassis that providesmechanical stabilityto components, including theAOM bracket.

Since the AOM bracket is partially covered by the support bar, you mustremove the bar firstto gain full access.

Step-by-Step Removal Process:

✅Step 1:Remove the screws securing the support bar.✅Step 2:Carefully lift and remove the support bar without tilting it.✅Step 3:Now, unscrew and remove the AOM bracket.

Why is False Incorrect?

IfFalse were correct, it would suggest that the AOM bracket can be removedwithout touching the support bar, which isnot possibledue to obstruction.

Official Documentation Reference:

Supermicro AS-8125GS-TNMR2 Disassembly Manualconfirms that thesupport bar must be removed first before accessing the AOM bracket.

To remove themidplane bracketin theAS-8125GS-TNMR2 system, you must remove4 screws total(2 on each side of the chassis).

Why 4 screws?

The midplane bracket is secured by 2 screws per sideto maintain its structural integrity.

Loosening all 4 screws allows safe removal without excessive force.

Forcing the bracket without removing the screws risks damaging the mounting points.

Incorrect Answers Explained:

A (2 screws total)→ Not enough, as screws on both sides must be removed.

C (8 screws total)→ More than necessary;only 4 screws hold the midplane bracket.

D (6 screws total)→ Incorrect count;only 2 screws per side are required.

Official Documentation Reference:

Supermicro AS-8125GS-TNMR2 Installation Guideexplicitly states thattwo screws on each side (4 total) must be removed to release the midplane bracket.

Removing themidplanein aSupermicro MI300X GPU systemrequiresdisengaging multiple system trays and power componentsbeforehand.

Why is this necessary?

Power must be fully disengaged before midplane removal

The midplane is directly connected topower distribution units (PDUs).

If power is not removed, it can causeshort circuits or hardware damage.

PCIe, motherboard, and GPU trays block access

These trays must be disengagedbefore removing the midplane, as they contain components directly connected to it.

Dummy PSUs must also be removed

Even inactive PSUs containlocking mechanismsthat must be disengaged.

Official Documentation Reference:

Supermicro AS-8125GS-TNMR2 System Removal Guideconfirms thatPSUs, dummy PSUs, PCIe trays, motherboard trays, and GPU trays must be removed before handling the midplane.
