As shown in the video, when returning any tray (GPU, motherboard, PCIe) back to the chassis, why must you screw in a tray at one end of the chassis first, before installing another tray at the opposite end of the chassis?
A.
Because the tray will get pushed out.
B.
Because the cables in the tray will get in the way.
When reinstalling trays (GPU, motherboard, or PCIe) inSupermicro MI300X GPU systems, it iscrucial to secure one end firstbefore working on the opposite end.
Why is this necessary?
To prevent tray misalignment
Trays in Supermicro systemshave specific guide rails and screwsthat must bealigned correctly before full installation.
If both ends are handled simultaneously,one end may shift, causingmounting misalignment.
Avoiding unwanted movement
If you install a tray at both ends without securing one first,it can get pushed out, leading to incorrect seating.
This can causepoor PCIe connectivity, power delivery issues, or misaligned airflow paths.
Ensuring cables are properly routed
If a tray is not secured properly,cables may shift during installation, increasing the risk of pinched or damaged cables.
Why other options are incorrect?
B (Cables getting in the way)→ While cable management is important, the key issue istray movement, not cables.
C (Tray will not function)→ The traywill function once properly seated, but incorrect installation cancause connectivity issues.
D (Tray will break)→ The tray is designed for durability;it will not break unless excessive force is applied.
Official Documentation Reference:
Supermicro AS-8125GS-TNMR2 Service Guideconfirms that traysmust be secured at one end before installing the opposite end to ensure proper alignment.
