Setting preferred airflow direction

The switch adopts pluggable fan trays, and two fan tray models are available for the switch. One model
has airflow from the port side to the power supply side. The other model has airflow from the power
supply side to the port side.
Upon startup, a switch automatically sets the airflow direction of the current fan tray as the preferred
airflow direction. When you use a fan tray with a different airflow direction to replace the current one, the
system outputs trap and log notifications to use a correct model. Follow these guidelines to solve this
problem:
If the new fan tray has a wrong airflow direction, use a correct model to replace it.
•
If you confirm that you installed a correct fan tray, you can set the airflow direction of this fan tray as
•
the preferred airflow direction to stop trap and log notifications.
To set the preferred airflow direction:
To do...
1. Enter system view
2. Set the
direction

Configuring the detection timer

Some protocols shut down ports under specific circumstances. For example, MSTP shuts down a BPDU
guard enabled port when the port receives a BPDU. Then, the switch starts the detection timer. If the port
is still down when the detection timer expires, the switch automatically brings up the port.
