Before reinstalling the motherboard tray, what critical step should be taken to ensure proper installation?

Why Must the Motherboard Tray Be Aligned With the Grooves?

TheSupermicro MI300X chassisis designed withbuilt-in alignment groovesthat helpprecisely position the motherboard tray.

If the tray is notaligned properly:

ThePCIe slots and mounting points will not line up correctly.

Thebackplane connections may be misaligned, leading to system boot errors.

Improper installation can block airflow, leading to potential overheating issues.

Step-by-Step Proper Reinstallation Process:

✅Step 1:Identify thealignment grooveson the chassis.✅Step 2:Slowly slide the motherboard tray into place, ensuring it follows the grooves.✅Step 3:Verify that the tray sitsflushwith the chassis.✅Step 4:Secure the tray with screws only after confirming proper alignment.

Why Other Options Are Incorrect?

B (Shake the tray to confirm fit)→ Shaking the traycan loosen connectors and potentially damage components.

C (Screw in randomly before aligning)→ If screws are installedbefore alignment, it can causeuneven seating and difficulty in securing other components.

D (Tilt the motherboard tray at an angle)→ The tray should be insertedstraight into the grooves, not at an angle.
