Chassis Airflow
The Cisco Nexus 7000 Series switches are designed to work in a hot-aisle/cold-aisle environment using
front-to-back, side-to-side, or side-to-back airflow. Each of these switches uses one of the following
airflow directions:
•
The Cisco Nexus 7004 switch uses side-to-back airflow to cool its modules and front-to-back
airflow to cool its power supplies as shown in
Figure A-22 . This switch requires right-side clearance
for airflow into the chassis.
• The Cisco Nexus 7009 switch uses side-to-side airflow to cool its modules and front-to-back airflow
to cool its power supplies as shown in
Figure A-23 . This switch requires right- and left-side
clearance for airflow into and out of the chassis.
•
The Cisco Nexus 7010 switch uses front-to-back airflow as shown in Figure A-24 .
• 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-25 . This switch requires right- and left-side
clearance for airflow into and out of the chassis.
