Task 3: Install Power Modules And Power On - Supermicro SSE-X3348S Installation Manual

The switch can be mounted in a rack using the included mounting brackets or optional
mounting rails. Due to the weight of the switch, it is strongly recommended that it be
supported by a rack shelf or by using Supermicro mounting rails (part number
CSE-PT052L).
For detailed instructions on rack mounting the switch, refer to the Quick Installation
Guide.
For general rack installation information, see the chapter
on page 4-1.

Task 3: Install Power Modules and Power On

Install power modules, connect the power cord, then power on. The switch supports up
to two PSUs that have a matching airflow direction as the installed fan tray
Installing the Power Modules and Powering On
1. If not already present, install one or two universal AC power modules in the switch.
2. Connect an external AC power source to the modules.
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.
