4.1 PCB Assemblies
The HPA677 is a backplane board. The HPA677 has two power supplies, the power-over-Ethernet ports
and the USB to I2C interface to support the HPA676. The HPA676 connects to the backplane board. The
HPA676 has the TPS23851 PSE controller and a power supply for the TPS23851. It controls port
connection to a valid PD.
Plug the HPA676 PCB assembly into the HPA677 backplane by aligning the three 10-pin connectors on
each board. See Board alignment photo, Figure 1.
Figure 1. Board Alignment
4.2 Power Supplies
Use either a laptop computer power supply or if not available, a lab power supply. No adjustment is
necessary with the laptop supply. Just plug the supply into J17.
With the lab power supply, if used, you must disconnected the output, turn on the power supply and adjust
the output voltage to 24 V +/-2 V. Adjust the supply current limit to 3 A. Connect the power supply output
to J9-1 and the supply GND to J9-2.
Connector J16 can be used to by-pass the 24-V to 54-V converter. This may be done if there is need to
vary 54 V when injecting a voltage into J16, remove any other input power at either J17 or at J9 when
using J16.

5 GUI Setup
1. Create a folder for the GUI and the National Instrument's download.
2. Go to National Instruments website and download and install the LabView Runtime Engine to the
new folder. Follow directions on screen. The download is free but you may be asked for a registration.
Use this link to get the runtime engine: http://joule.ni.com/nidu/cds/view/p/id/1101/lang/en. Download
LVRTE86std.exe and install.
3. Copy the attached file, TPS23851 GUI Software, to the new folder on the PC and unzip. Go to folder
TPS23851GUI and Double-click TPS23851.exe.
4. The GUI should start. Power the EVM and plug in a USB cable from computer to EVM. The green LED
at D1 will turn on.

The I2C device address is set in the hardware for address 20h. The GUI also defaults to this address. If a
different address is needed, go to the GUI's right half of the screen's Setup Tab and enter the new I2C
address. See Figure 3.
Also in the Setup Tab screen, the 400-kHz I2C (default) is selected.
Leave the termination set to the default setting, open.
Figure 3. Interrupt/Events and Setup Tabs
Select the Configuration Tab (reference Figure 4). At the far right in the Configuration Screen, the
selections are global which means they apply to all 4 ports. At the pull down that says Manual, select
AUTO, and select the r0x12h Button just to the left of AUTO. The four columns to the left get set to
AUTO.
To the left of GLOBAL on this same screen the window allows individual set up for each output port.
Those selections are then applied using the r0x12h Button to the left of the four-port mode entries.
Detection and classification are initiated within the parameters of the mode already selected by either
global or single port selection in the same way the mode was set. Then click the r0x14h Button to
activate. Classification and detection can be set or cleared before initiation with the green CLEN and DEN
Rectangular Buttons The green LEDs turn on for good status indication.

Plug in a valid PD load to any of the four left-side ports and the load will be powered. The connectors are
ordered Port 4 thru Port 1 where Port 4 is the leftmost connector. The right-side 4 connectors are not
operational but are included for expansion. Left or right is determined by facing the port connectors plug
input side.
After an operator action in the GUI, the resultant event may be checked in other GUI windows tabs such
as Events or Interrupts.Interrupt/Event Tabs are shown in the left half of Figure 3. Follow the tabs to
get to the proper window to check results.
RUN and STOP are in the upper left corner of the GUI screen. The GUI is running when the arrow is
black filled.
Reset is not active from the GUI Button. Reset can be done through the on-board push button switch.
Auto is grounded so all ports reset or power-up OFF.

FCC Warning
This evaluation board/kit is intended for use for ENGINEERING DEVELOPMENT, DEMONSTRATION, OR EVALUATION
PURPOSES ONLY and is not considered by TI to be a finished end-product fit for general consumer use. It generates, uses, and
can radiate radio frequency energy and has not been tested for compliance with the limits of computing devices pursuant to part 15
of FCC rules, which are designed to provide reasonable protection against radio frequency interference. Operation of this
equipment in other environments may cause interference with radio communications, in which case the user at his own expense
will be required to take whatever measures may be required to correct this interference.
EVM Warnings and Restrictions
It is important to operate this EVM within the input voltage range of 40 V to 60 V and the output voltage range of 40 V to 60 V .
Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are
questions concerning the input range, please contact a TI field representative prior to connecting the input power.
Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to the
EVM. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load
specification, please contact a TI field representative.
During normal operation, some circuit components may have case temperatures greater than 80° C. The EVM is designed to
operate properly with certain components above 80° C as long as the input and output ranges are maintained. These components
include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of
devices can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near
these devices during operation, please be aware that these devices may be very warm to the touch.
