Why Secure One End of the PCIe Tray First?

TheSupermicro MI300X chassis is designed for modular tray installation, meaningsecuring one end firstensures:

Proper alignment of PCIe slots and connectors

Stable mountingto prevent unwanted movement

Prevention of unnecessary strain on installed expansion cards

What Happens If Both Ends Are Handled at the Same Time?

ThePCIe tray may shift out of alignment, making it difficult to properly install other components.

Misalignment can cause:

PCIe devices to not seat properly

Power or data cables to be obstructed

Increased risk of mechanical damage during reinstallation

Step-by-Step Correct Installation Process:

✅Step 1:Align the PCIe tray with its designated mounting slots.✅Step 2:Secure screws onone end firstto hold the tray in place.✅Step 3:Adjust the other end and ensureproper seatingbefore fully tightening all screws.✅Step 4:Reconnect all PCIe cables and verify system connectivity.

Why Other Options Are Incorrect?

B (Cables getting in the way)→ While cable management is important, the main issue istray movement, not cable obstruction.

C (Tray will not function)→ The tray will functiononce properly seated, butincorrect installation can lead to PCIe misalignment.

D (Tray will break)→ The tray is designed for durability; it will not break unlessexcessive force is applied.

Official Documentation Reference:

Supermicro AS-8125GS-TNMR2 Service Guideconfirms thattrays must be secured at one end first to ensure proper alignment.

Themidplane bracketinSupermicro MI300X GPU systemsconnects multiple crucial components, includingstorage, PCIe devices, and power distribution systems.

Why must the MCIO and Flat Panel/Ribbon cables be removed?

MCIO Cable (Option B)→

MCIO (Multi-lane Cable I/O)cables are responsible forhigh-speed NVMe communicationbetween the motherboard and storage components.

These cables must bedisconnected before midplane removal, asforcing them out without removal can cause connector damage.

Flat Panel/Ribbon Cable (Option C)→

Theflat panel/ribbon cableis used forsystem communication, front panel connectivity, or sensor data transmission.

If not removed, it can be torn or pinched, leading tomalfunctioning front panel indicators, buttons, or management controllers.

Incorrect Answers Explained:

A (Power cable)→ Power cables are usuallysecured independentlyand arenot directly attached to the midplane bracket. Removing them isnot a required stepfor midplane bracket removal.

D (SATA cable)→ SATA cables arefor legacy storage systemsanddo not need to be disconnectedunless working on SATA-specific backplanes.

Official Documentation Reference:

SupermicroService ManualforAS-8125GS-TNMR2explicitly states thatMCIO cables and ribbon cables must be removed before handling the midplane bracketto preventsystem damage.

Thecorrect and safemethod to remove the backplane from the motherboard tray is to useboth hands, gently tilting thetop of the backplanetowards yourself while carefullylifting it up and outof the motherboard tray.

This ensures that:

No undue forceis applied to the connectors or PCB.

No components or cablesare unintentionally damaged.

Proper handling of static-sensitive componentsis maintained.

Removing the backplane improperly can result in:

Connector damageto the motherboard or backplane.

PCB warping, which could lead to future malfunctions.

Potential data center downtimedue to component failure.
