Facility Cooling Requirements
Facility Cooling Requirements
The Cisco Nexus 7000 Series switches dissipate considerable power that generates much heat. The
following is the heat dissipation requirement for these switches:
• Cisco Nexus 7010 dissipates up to 35,162 BTUs per hour
• Cisco Nexus 7018 dissipates up to 51,195 BTUs per hour
Chassis Airflow
The Cisco Nexus 7000 Series switches use either front-to-back or side-to-side airflow for d evice cooling.
The Cisco Nexus 7010 switch uses front-to-back airflow as shown in Figure A-13, and 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-14. Both 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.
