A 5kW (power consumption) server keeps crashing with the message ‘temperature too high’.- The intake temperature is measured at 25 °C/77 °F and a relative humidity (RH) level of 50%.- The exhaust temperature is 29 °C/84 °F and 45% RH.- The raised floor is providing adequate amount of CFM/CMH at a reasonable velocity.- The pressure under the raised floor is approximately 25 Pa/0.1 inch H20. Analyze the situation and indicate what the most likely cause is for this server to crash.

1. A. Dust inside the server causing issues with convection-based heat transfer — đáp án hiện tại
2. B. The exhaust temperature is exceeding the ASHRAE recommended values
3. C. The raised floor pressure is too low and/or the raised floor tile % opening is not adequate
4. D. No cause could be determined as the CFM/CMH of the air conditioning equipment is not stated
