IMPORTANT:
•
At the first login to the switch, use the
fan
prefer-direction
command to set the airflow direction
of the switch to be the same as the airflow direction of the fan tray. If the fan tray has a different
airflow direction than the switch, the system outputs traps and logs to notify you to replace the fan
tray.
•
By default, the switch uses the same airflow direction (power-to-port) as the LSWM1FANSCE fan
tray.
