Exhibit:When installing the midplane bracket back into the chassis, what design feature in the chassis...

Why Do Supermicro Systems Use Grooves for Alignment?

InSupermicro MI300X systems, themidplane bracket is aligned using built-in grooves in the chassis.

Ensures Perfect Alignment

The midplane mustline up perfectlywith power, PCIe, and data connections.

Grooves act as physical guides, ensuringprecise placementwithout guesswork.

Prevents Installation Errors

Without grooves, technicians mightinstall the midplane slightly misaligned, leading toconnection failures.

Ensures PCIe and MCIO lanes align correctly, preventing signal loss.

Supports a Tool-Free Installation

Grooves allowdrop-in installation, reducingmanual adjustments.

Minimizes risk of flexing or damaging the midplane PCB.

Why Other Options Are Incorrect?

A (Guide stickers in the chassis)→ Stickersmay be present for labeling but do not physically align the midplane.

C (Arrows in the chassis)→ Arrows arevisual indicators only, not physical alignment tools.

D (Velcro in the chassis)→ Velcro isnot used in midplane installation.

Official Documentation Reference:

Supermicro AS-8125GS-TNMR2 Hardware Guideexplicitly states thatgrooves in the chassis help with midplane bracket alignment.
