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:

Chassis Airflow

The Cisco Nexus 7000 Series switches use either front-to-back or side-to-side airflow for device cooling.
The Cisco Nexus 7010 switch uses front-to-back airflow as shown in
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
environment, but the Cisco Nexus 7018 switch design also requires side clearances to allow airflow in
and out the sides.
