Introduction

Microsemi’s PD-IM-7504B Marketing Board (see Figure 1) provides designers with the needed environment to evaluate the performance and implementation of PoE and PoE extended mode applications, based on PD69104A/B/B1 PoE Manager. The marketing board enables PoE designers to evaluate Microsemi’s PoE solution with maximum flexibility and ease in configuration
All necessary steps and connection instructions required for installing and operating this board are provided within this document.

2.1 Marketing Boards Ordering Information
Microsemi supplies the following Marketing Boards as detailed below:

2.2 Marketing Board Features

• Designed to support four RJ45 ports, PoE application, and PoE extended mode (2-pairs)
• Vin connector – DC jack
• On-board LEDs indicators
• Reset button
• EEPROM support
• I2C and UART communication connectors.
• Marketing Board working temperature: 0°c to +50°c
• RoHS compliant

2.3 Marketing Board Interfaces and Connections
Board has several interfaces:

• RJ45 interface: Running from PD69104A/B/B1 to 4 PDs (powered devices)
• Vin connectors: DC in (Vmain) connection (J1)
• LEDs indication: Vmain power OK, Power limit LEDs
• UART connector: for UART communication.
• I²C connector: for I²C communication or EEPROM configuration.

2.4 Physical Characteristics
The following table lists the Marketing Board’s physical characteristics.
Physical Characteristics

2.5 Communication

• I²C –Marketing Board is set to work with I2C communication through connector JP1, with Aardvark (http://www.totalphase.com/products/aardvark_i2cspi/) or any other I²C master.

** When configuring EEPROM, connect this pin to GND.

• UART- connecting through J2 pins:

• E² PROM – When no host controls the IC and configuration should be other than the default, an EEPROM may be used for uploading new configurations. EEPROM can be burned by JP1.

Physical Description

3.1 Package Contents
Upon opening the Marketing Board package, verify all parts itemized in the packing list are included. If any part is missing or seems damaged; contact a local representative or Microsemi’s Headquarters. Package contents for standard shipments are as follows:

• PD-IM-7504B Marketing Board
• 55V power supply Adapter + AC cord

3.2 Reset Button
The dedicated Reset button SW1 (see Figure 1) is utilized to reset the PD69104A/B/B1 PoE manager.
3.3 Connectors
The following sections provide both general and detailed information regarding unit connectors.
3.3.1 Connectors Table
The following table lists Marketing Board’s connectors.

Table 1: Connectors List

Marketing Board
2| J2| UART connector| UART communication connector. (3.3V compatible) Can use PD-0600 (Microsemi USB to UART converter) or any equivalent equipment
3| J3| RJ45 connectors| Four RJ45 ports for connecting to the powered device
4| JP1| 12C connector| Connection to I2C communication through AARDVARK or any other equivalent equipment (3.3V compatible)

3.4 Vin DC jack connectors (J1)
See Figure 2.

supply
Hole 2(left)| GND(Vin -)| Used for soldering wires to the external power supply

Since provided power supply can’t support four ports PoE + full load (4*0.6A=2.4A), a wired connection can be used for connecting the laboratory power supply directly to PCB using the holes located near J1.

3.5 LEDs Indication

• D1 – VMAIN indication.
• D3 – MAX power indication. (Indicates power budget is reaching its limit)
• Port Status LED– in front of each port in the RJ45 connector there is a green LED that indicates whether the port is operating. See Figure 4

Electrical Characteristics

The marketing board’s electrical characteristics are listed below:
Table 3: Electrical Characteristics

Installation

This chapter describes the steps required for installing and operating the Marketing Board with any PoE application.

5.1 Preliminary Considerations and Safety Precautions

• Prior to powering the board, connect all required peripherals.
• Never hot swap peripherals units!
• Verify board is properly configured prior to turning on the power supply.

5.2 Default Configuration

• The current set is configured to AT mode (600mA). If the “AF” current (350mA) has to be changed, load 0Ω to R11.
• Communication mode set to I²C (R5 is loaded with 0Ω). If UART is required, disconnect R5 and connect 0Ω to R8.
• PoE Auto mode.

All configurations can be set by communication or EEPROM.
