Install Power Modules and Power On
Install power modules, then power on. The switch supports up to two PSUs that
have a matching airflow direction as the installed fan tray.
Caution:
The switch includes plug-in power supply and fan tray modules that are
installed into its chassis. All installed modules must have a matching airflow
direction. That is, all modules must have a front-to-back (F2B) airflow direction, or
all modules must have a back-to-front (B2F) airflow direction. The airflow direction
of PSUs and fan trays is indicated by labels on the modules.
