Usage setup and Configuration
This section contains information about the setup and configuration of the POEPHYTEREV-I/-E evaluation
board, including descriptions of the card's interfaces, connectors, jumpers and LEDs.
Power for the POEPHYTEREV board can be supplied by a number of means:
•
MII connector J1
•
PoE over unused pairs
•
PoE over data pairs
•
External supply to P1
•
If 5V is supplied from the MII connector, the on-board voltage regulator, U2, will convert 5V to 3.3V for
the PHYTER®. J7 should be removed.
•
If 3.3V is supplied from the MII connector, J7 needs to be ON (see
Section 8
for details).
•
Only applies to the circuit board version with PCB serial number 551013040-001 Rev A: J7 should be
shorted if the PoE main output is set at 3.3V, which is the default factory setting. To modify the output
to other higher voltages, a 3.3V LDO should be installed onto U2 and J7 must be open.
Address Settings:
The PMD address for the DP83848 Physical Layer device is set by jumper J3.
•
Default board setting for the PHY Address is 01h
•
The board may be set to PHY Address 03h by adding jumper J3

Link - DS3*
Media Speed - DS2
Activity/Collision - DS4*
Ethernet Device Power - DS1
PoE Power - LED1
*Other status can be indicated by these LEDs. The alternate status is set by adding jumper J5. Refer to
PHYTER Extreme Temperature Single Port 10/100 Mb/s Ethernet Physical Layer Data Sheet (
SLLSEC6
)
for additional information.
