maintain the designed airflow and fan redundancy.

Operations
The Cisco Nexus 7018 chassis uses two fan trays to cool its modules. The top fan tray cools slots 1
through 9 and the fabric modules, and the bottom fan tray cools slots 10 through 18. Each fan tray is
designed to be removed and replaced while the system is operating, but you should replace the fan tray
within three minutes or the switch will shutdown the modules cooled by the missing fan tray when the
time expires.
