Chassis Airflow
The Cisco Nexus 7000 Series switches use either front-to-back or side-to-side airflow as follows:
• The Cisco Nexus 7009 switch uses side-to-side airflow to cool it modules and front-to-back airflow
to cool its power supplies as shown in Table A-14.
• The Cisco Nexus 7010 switch uses front-to-back airflow as shown in Figure A-15.
• The Cisco Nexus 7018 switch uses side-to-side airflow to cool its modules and front-to-back airflow
to cool its power supply units as shown in Figure A-16.
All Cisco Nexus 7000 Series switches are designed to work in a hot-aisle/cold-aisle environment, but the
Cisco Nexus 7018 switch design also requires side clearances to allow airflow in and out the sides.
