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.
