Correct answers: A, B, D
Explanation
Replacing a faulty GPU in an NVIDIA DGX system requires careful adherence to safety and operational procedures. Powering down the system, using ESD protection, and verifying proper installation are crucial steps to ensure the replacement is successful. Performing diagnostics should only occur once the system is powered back on and reassembled.
- A. Correct.
Powering down the system and disconnecting it from the power source is essential for safety and to avoid damaging the hardware during the replacement process.
- B. Correct.
Wearing an ESD wrist strap is a best practice to prevent static electricity from damaging sensitive components, including GPUs.
- C. Incorrect.
Replacing the GPU while the system is powered on is highly unsafe and can cause permanent hardware damage or even injuries.
- D. Correct.
Ensuring the replacement GPU is properly seated and all connections are secure is critical for the system to function correctly after the replacement.
- E. Incorrect.
Running diagnostic tools like DCGM should be performed after the system is powered back on and the GPU replacement is complete, not while the system is powered off.
