3.2. Installing the PoE USB Adapter
Note: Before the PoE USB adapter is plugged in, the device driver should be installed.
To install the PoE USB adapter drivers, run PoEUSBSetup.exe from the supplied disk, and follow the instructions
including accepting the end user license agreement. The PoE USB adapter supplied with the Smart PSE-24 Kit
has been tested to be compatible with Windows XP
®
, Windows Vista
®
, and Windows 7
®
operating systems.
After successful installation, plug in the USB cable; the PoE USB device should be recognized. For Windows XP,
select “No not at this time” when Windows prompts to search for software, and select “Install the software
automatically” on the next screen. After successful installation, a PC reboot may be required.
4. Demonstration Use of the Power Manager GUI
The Silicon Labs power manager GUI is used to configure and observe the Smart PSE 24 via the supplied PoE
USB adapter. See the Si3452 Power Management GUI user’s guide for detailed installation instructions. Note that
once the Si3482 has been configured, it can run in hardware only mode without the GUI or PoE USB-to-UART
adapter.
The demonstration assumes the Power Manager GUI has been used to configure the Si3482 as follows:
 40 W of power available on Power Supply 2. Set Power Supply 1 to zero for demonstration in the standalone
mode. This is because, in the standalone mode, the control line for Power Supply 1 status is low (disabled)
when the USB cable is unplugged.
 Port 1 High Power (PoE+, 30 W) all other ports standard PoE (15.4 W)
 Port 1 critical priority; all other ports low priority
 Consumption-based power management
 Retry after reconnect for overloads

 Power Supply 2 inserted. Power Supply 1 can be inserted or not as its power capacity is set to zero. Power
Supply 3 should also display as not inserted if JP 9 is set low. Power Supply 3 cannot be controlled by the GUI
when using the Smart PSE 24 Kit because jumper JP9 sets the status.
