A.  

mlxfwreset -d -lid 27 reset --yes to reset the transceiver

B.  

Physically disconnect and reconnect the transceiver.

C.  

flint -d -lid 27 --linkx --linkx_auto_update --activate

A.  

Use Power Usage Effectiveness as the primary metric while supplementing it with additional measures of useful work done per unit of energy.

B.  

Use watts used as the primary measure of efficiency, as it accurately reflects the power input at any given time.

C.  

Develop benchmarks tailored to specific workloads, such as MLPerf for AI applications, to better understand energy use in real-world scenarios.

D.  

Focus on integrating kilowatt-hours into existing metrics to better reflect the actual energy used for productive work.
