Note 

The airflow in the Catalyst 6840-X switch chassis is from front to back. See Site Requirements for recommended separations between walls and the chassis air intake and air exhaust and between the air exhaust of one chassis with the air intake of another chassis. Failure to maintain adequate air space can cause the chassis to overheat and the system to fail.
