Description Use this command to configure the fan airflow direction to match the physical PSU and fans
installed in the system.
Usage Guidelines This command applies to the Brocade VDX 6710, VDX 6720, and VDX 6730.
This command must only be used after you purchase and install the appropriate fan/power supply
that provides the desired airflow direction in the switch. Please contact your Brocade Sales
Representative to obtain the correct part numbers and pricing.
When the chassis fan airflow-direction command is issued, the switch will not recognize the
configuration change until the switch is rebooted.
Only one (1) configuration change is accepted per reboot. This means that even if this command is
entered multiple times, only the first configuration change entered will be effective after rebooting.
The switch serial number is registered with Brocade and the information recorded in the Brocade
database about that switch includes the airflow orientation at the time of shipment.
Any subsequent change in airflow direction is not recorded in the Brocade database. This means
that if you request a Return Merchandise Authentication (RMA) for the switch, the replacement
switch will be sent with the original orientation.
Examples To specify the fan airflow-direction:
switch# chassis fan airflow-direction port-side-exhaust
Previous configuration : port-side-intake
Current configuration : port-side-exhaust
System fan airflow-direction changes will be effective after reboot!!
