What to do next
You are ready to mount the chassis to the two-post rack.
Installing the Chassis in a Two-Post Rack
You need to position the chassis near the top of the rack with the power supply and fan modules in the
appropriate aisle for their required airflow. If the fan modules have a blue coloring for port-side exhaust
airflow, then you must position the modules by the cold aisle. If the fan modules have a burgundy coloring
for port-side intake airflow, you must position the modules by the hot aisle.
Note
Power supply modules must have the same airflow direction as the fan modules.
Note
Power supply modules must have the same airflow direction as the fan modules but might have different
coloring if they use DC power (green coloring for port-side intake airflow or gray coloring for port-side
exhaust airflow). HVAC/HVDC power supplies with white coloring use the same direction of airflow as used
by the fan modules.
