exceed 122°F (50°C). Exhaust air should have few or no restrictions. Obstructions
such as cabling or other devices that block airflow to the side or top of the rack
should be avoided.
If you are concerned about inlet air temperature, you should measure the
If you are concerned about inlet air temperature, you should measure the
temperature of the inlet air in the actual rack as you plan to use it. You should have
all cabling in place and all adjacent units installed and running.
