airflow for cooling the switch. If you are positioning the port end of the switch in a cold aisle, make sure that
the switch has port-side intake modules with burgundy colorings on the fan and AC power supplies and green
markings on DC power supplies. If you are positioning the fan and power supply modules in a cold aisle,
make sure that the switch has port-side exhaust modules with blue colorings.
