Si3452MS8-KIT Si3452MS8 EVALUATION BOARD USERS GUIDE 1. Introduction The Si3452MS8 8-port evaluation kit (Si3452MS8-KIT) is intended for Power over Ethernet (PoE) Power Sourcing Equipment (PSE) system designers interested in evaluating the Quad-port Si3452 PSE controller. While evaluation kits are normally shipped with Si3452 devices that use Silicon Laboratories proprietary dV/dt disconnect, they can also be used for evaluation of the pin-compatible Si3453, which uses dc disconnect. In this case, the Si3452 devices must be replaced with the appropriate Si3453 device. Please refer to8. Ordering Guid on page 35 for more information. 2 The Si3452 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 Si3452 I C registers. The evaluation kit assumes the user has access to a PC to control the evaluation board with 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 Si3452 can supply over 30 W to each port. Thus, the two Si3452 controllers for the eight 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 does not implement system-level power management. Contact Silicon Laboratories for more information about system-level power management options. The Si3452MS8 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.

An optional Power Manager GUI is described in the SI3452 Power Manager GUI users guide on the CD-ROM. The installation instructions for 2 the hardware and USB to I C driver in this users guide must be followed before installing and using the Si3452 Power Manager GUI. Table 1. Evaluation Kit Contents Kit Contents Si3452MS8-EB r1.1 The Si3452 8-port evaluation board with connector for an external 50 V power supply. The power supply must be capable of supplying the required amount of power for all PoE loads being connected. Standard boards are populated with Si3452-B01-GM parts. Si3452CB-EB r1.1 An RJ-45 connector board configured as power over Ethernet Gigabit mid-span injector. A 24-wire cable to connect the Si3452 evaluation board to the mid-span injector board 2 PoE USB v1.3 A USB to I C (or SMBus) evaluation board. This board is preconfigured with updated firm- 2 ware to support I C transactions. A USB cable to connect to a host PC Si3402ISO-EB A PD evaluation board configured to provide a Class 3 signature. Si3402ISO-C4-EB A PD evaluation board configured to provide a Class 4 signature. 10 loads for the evaluation boards. Each load will consume 2.5 W, which is about 3 W referred to the PSE side. Two Ethernet cables to connect the Si3400 and Si3401 evaluation boards to the connector board. CD-ROM Software drivers for the USB to SMBus adapter and a GUI for the Si3452 registers on a CD-ROM.
