How would you identify and differentiate a failed GPU that needs to be replaced from...

A failed GPU in the Supermicro MI300X system can be identified usingthe warning light indicator. Supermicro systems includeLED diagnostic indicatorsthat display the operational status of various components, including GPUs. When a GPU malfunctions, the system will trigger an alert that is displayed as a warning light on the GPU tray or the server chassis. This allows technicians to visually identify the faulty GPU without requiring extensive hardware testing.

Discoloration (A)is not a reliable method of identifying a failed GPU as it would require physical degradation, which is uncommon.

Serial numbers (B)andPart numbers (C)are used for inventory tracking but do not indicate functional status.

Warning lights (D)are the recommended method, as documented in the system health monitoring section of Supermicro's documentation, which detailsLED indicators and diagnostic lights for system status monitoring​.
