Data Center Deployment
– 15 –
When mounted in a rack with other network equipment that may have a back-to-
front (B2F) airflow direction, the top-of-rack switch includes two fan trays that
reverse the airflow direction through the switch. This enables flexible deployment
options for the switch in the data center.
