Single Port Gigabit Ethernet Board Operation:
The Gigabit Ethernet board has two main electrical connectors: the Ethernet RJ-45 and the
2-pin Phoenix DC power connector.
The RJ-45 connector (J6) is located at the lower right side of the board and is a standard 8-
pin Ethernet connector with an integrated transformer. Depending on the ordering options,
the RJ-45 connector may or may not have a pair of integrated Ethernet status LEDs.
Whether or not the connector has the integrated LEDs, there is an additional 2-position
LED for indicating Ethernet link status and link activity.
There is single green 2-pin Phoenix connector (J2) on the on the upper right side of the
board for supplying the board with DC operating power. Pin 1 (at the lower right of the J2
connector) is the +DC input and pin 2 (at the upper right and labeled “GND”) is the ground.
Depending on the ordering options for this board, various DC supply voltages can be
accommodated from +5VDC to +24VDC.
The SFP optical module (J4) is located at the lower left of the board. Depending on the
ordering options, the optical module may have one or two integral LC optical connectors. If
there are two optical connectors then the upper left connector is the transmit (TX) optical
port while the lower left connector is the receive (RX) optical port.
NOTE: On power-up of the board, both LEDs within LED3 will briefly flash on then
off to indicate that the GBE chip (U3) is starting. Even if the two boards are optically
connected, neither LED on LED3 will light until a valid GBE signal is present at
BOTH RJ-45 connectors. Once valid GBE signals are seen at both ends of the link
then the LEDs on LED3 will activate.

Gigabit Ethernet Board Indicators and Controls:
LEDS:
There are 3 through-hole right angle LED indicators on the top of the board. There are no
LEDs on the bottom of the board.
LED
Indication
LED1 (Green)
Single LED, located at the top right of the board, labeled „PWR”, serves as an indicator that
+VDC power is available to the board. Supply voltage range depends of ordering options.
LED2
(Green/Green)
Dual LED, located on the right center of the board, labeled „1.2/3.3VDC‟.
When „ON‟, the upper LED provides an indication that the on-board 1.2VDC regulator is
functioning.
NOTE: THE UPPER LED (1.2V) DOES NOT FUNCTION ON THE REV A PCB
VERSION.
When „ON‟, the lower LED provides an indication that the on-board 3.3VDC regulator is
