NCP-AII Question 18
Select 3You are managing an NVIDIA DGX system that has reported a critical error indicating one of the GPUs has become unresponsive. After initial diagnostics confirm the issue is hardware-related, what steps should you follow to safely replace the faulty GPU?
- A
Power off the system completely and disconnect it from the power source before replacing the GPU.
- B
Use the NVIDIA System Management Interface (nvidia-smi) to disable the faulty GPU before removing it.
- C
Ensure you are grounded using an anti-static wrist strap to avoid electrostatic discharge during the replacement process.
- D
Replace the faulty GPU while the system is powered on to minimize downtime for other components.
- E
Verify the replacement GPU is securely seated and perform a system test to confirm functionality after installation.
Show answer and explanation
Correct answers: A, C, E
Explanation
Replacing a faulty GPU requires following proper safety procedures to protect both the hardware and yourself. The system must be powered off and disconnected from the power source, and grounding yourself with an anti-static wrist strap is necessary to prevent electrostatic discharge. After installing the replacement GPU, a system test is critical to ensure it is operational. Steps like disabling the GPU via nvidia-smi or performing a hot-swap are not appropriate in this scenario.
- A. Correct.
Powering off the system and disconnecting it from the power source is crucial to ensure safety and prevent damage to other components during the GPU replacement process.
- B. Incorrect.
Disabling the GPU using nvidia-smi is not necessary for physical hardware replacement. The system must be powered off before replacing the GPU.
- C. Correct.
Grounding yourself with an anti-static wrist strap is an essential step to prevent electrostatic discharge, which could damage sensitive components like the GPU.
- D. Incorrect.
Never replace a GPU while the system is powered on. Doing so can lead to hardware damage or even personal injury.
- E. Correct.
After installing the replacement GPU, verifying that it is properly seated and performing a system test ensures the replacement was successful and the system is functioning correctly.
