1. Introduction
The Si3454 8-port evaluation kit (Si3454-KIT) is intended for Power over Ethernet (PoE) Power Sourcing
Equipment (PSE) system designers interested in evaluating the 4-port Si3454 PSE controller.
2
The Si3454 is controlled through an I
C (or SMBus) interface. For convenience in evaluation, a graphical user
2
interface (GUI) is provided, giving an easy-to-use visual display and control of the Si3454 I
C registers. The
evaluation kit assumes the user has access to a PC to control the evaluation board using the provided GUI.
The user is also responsible for providing an appropriate high-voltage power supply. The power supply should be
45 to 57 V for normal PoE or 51 to 57 V for PoE+. The Si3454 can supply over 30 W to each port. Thus, the two
Si3454 controllers for the 8-port demo system can provide over 240 W of total power. Normally, a 50 to 100 W
power supply is used. While the classification and actual current consumption of each port is available, the demo
GUI interacts with the Si3454 on a per-port basis and does not implement system-level power management.
Contact Silicon Laboratories for more information about system-level power management options.
The Si3454-KIT kit has been thoroughly tested for standards compliance and interoperability. Contact Silicon
Laboratories for test reports using Sifos PoE test equipment and University of New Hampshire PoE standards
compliance and interoperability reports.

    Si3454-KIT 3. Installation This KIT contains a PC-based Monitor GUI. Before you can use the Monitor, you must first install the device driver associated with the PoE USB Adapter card (called “PoEUSB” in this document), then install the Monitor GUI.
  • Page 4 Si3454-KIT 3.2. Installing the Si3454 & Si3459 Monitor If you have previously installed the Monitor, uninstall the previous version before installing the new version. To uninstall the previous version, select “Programs and Features” or “Add or Remove Programs” from the Control Panel, and then uninstall the outdated application.

    Si3454-KIT 5.4. Device Information The Device Information box displays high-level information about the Si3454 device, including hardware revision and the firmware version. Note: The example shown in Figure 11 is representative but may not contain the same data as that displayed with your board.

  • Page 11: Interrupts And Events

    Si3454-KIT 2. Enable the 2 event classification by checking the "2 event class. enable" check box. 3. Watch for a successful 2 event classification by checking the state of the “2-event class.” LED 4. Once the classification is successful, set the Ilim to 850 mA 5.

  • Page 12: Register List

    Si3454-KIT Figure 13. Interrupt Enable and Events Boxes 5.6.2. Events The Events box shown in Figure 13 displays the status of the interrupt line and the port events. The GUI events section indicates both global and port-specific events. Each events register consists of a pair of read-only (RO), and clear-on-read (CoR) registers with the same event bits.
  • Page 13 Si3454-KIT Figure 14. Register List The Register List displays all of the Si3454’s registers grouped by category. Each category of registers can be expanded and collapsed by clicking on the plus and minus signs at the left edge of the Register List.
  • Page 14 Si3454-KIT The user may specify which registers to read (when the GUI is updated) by checking a box at the left of each register name. Refreshing, polling, and RoM, all depend on these settings. Clear on Read registers are read only if both the CoR check box is checked and the check box for the individual CR register is checked.

  • Page 15: Operating The System

    Si3454-KIT 6. Operating the System Each RJ45 connector board has eight LEDs for the eight ports. Each LED is driven by a comparator circuit which detects when a voltage is forced to the load at the PoE output. When the ports are in auto mode, the LEDs in the RJ45 connector board flash, indicating the detection cycle until a valid PD is connected.
