The AGFHC tool for Ubuntu must be installed in the /opt/AMD/AGFHC directory.

Option A (Incorrect): The /tmp/ directory is temporary storage and is not used for application installations.

Option B (Incorrect): /windows/user/desktop is a Windows path and does not apply to Linux-based Ubuntu.

Option C (Incorrect): /usr/home/customer/AGFHC is not the correct standard directory for system-wide software.

Option D (Correct): /opt/AMD/AGFHC is the correct directory for installing AMD-related tools in Ubuntu.

When working with Supermicro MI300X GPU systems , it is highly recommended to map or take a picture of cable connections before disconnection.

Reasons:

Ensuring Proper Reconnection → NVMe backplanes have multiple critical connections (MCIO cables, power cables, data lanes, and SAS connections). Misplacing any of these cables could cause:

Boot failures

Drive detection issues

Performance degradation

Avoiding Errors in Cable Routing → Supermicro documentation states that improperly routed cables can obstruct airflow , potentially leading to overheating in high-performance systems.

Easing Future Troubleshooting → If issues arise after reassembly, a photo or cable map allows engineers to quickly verify whether cables were reconnected properly .

This best practice is officially recommended in Supermicro’s service and installation guidelines for NVMe backplanes.

The IPMI Dashboard health event log helps identify component failures using a red severity status indicator . If a fan or power supply fails, the event log will mark it as a red alert , allowing users to take corrective action.

Option A (Correct): Red severity status in the event log signals a failed component.

Option B (Incorrect): Fans do not change colors when failing.

Option C (Incorrect): There is no purple status indicator in IPMI for failures.

Option D (Incorrect): You cannot configure a new fan in IPMI under Configuration ; you must replace a failed fan.

The GPU in the MI300X system is secured with T15 Torx screws , requiring a T15 Torx Bit for removal.

Option A (Incorrect): T20 Torx Bit is too large for GPU screws.

Option B (Incorrect): Security Torx Bit is not required for standard GPU removal.

Option C (Correct): T15 Torx Bit is the correct tool for removing GPU screws.

Option D (Incorrect): Phillips Head Screwdrivers do not fit the GPU screws.

The correct syntax for running recipes using the AGFHC tool is:

bash

CopyEdit

/agfhc -r alljvll.yml

This command runs a specified YAML recipe file (alljvll.yml) using the AGFHC tool in a Linux-based system .

Option A (Incorrect): Contains an incorrect flag (-r should be separated).

Option B (Incorrect): Uses incorrect flag format (-t -a), which is not part of AGFHC syntax.

Option C (Incorrect): Uses Windows-style .exe format, which is incorrect for Linux.

Option D (Correct): This follows the correct AGFHC syntax for running recipes in a Linux environment.

When the GPU tray is pulled out partially , it locks in place to prevent accidental removal or dropping . To fully remove it, two people must press down on the lever on each side before continuing.

Option A (Correct): The tray locks automatically to ensure safe removal, and two people are needed to press the unlock levers.

Option B (Incorrect): The tray does not vibrate or flash red when released.

Option C (Incorrect): The tray does not contain liquid components .

Option D (Incorrect): The tray does not generate excessive heat upon removal .
