Chassis Airflow
Figure A-25 Airflow for the Cisco Nexus 7018 Chassis
For the Cisco Nexus 7004 switch, you can route cables on the left or right side without interferring with
coolant airflow, which goes in on the right side. Be sure to otherwise leave the right side unblocked so
that cool air can flow from the cold aisle in the front to the chassis.
To allow for the Cisco Nexus 7009 and 7018 switches to take in air from the cold aisle and floor on the
right side, you should route cables on the left front side of the switch. If necessary, you can route cables
on the upper right front side of the chassis, which leaves the lower right side open to cooling air from
the cold aisle in front of the chassis. By having the cables on the left side and leaving the left rear side
unobstructed, the exhaust is directed to the hot aisle in back.
For the clearances required on each side of the switch, see the “Chassis Clearances” section on
page A-21 .
