4 Port 10/100/1000 Mbps Ethernet Switch Indicators and Controls
LEDS: There are 7 surface mount (SMD) and 4 dual through hole LED indicators on the 4 Port
10/100/1000 Mbps Ethernet Switch. In addition, there are 8 LED indicators that are built into the 4
position RJ-45 connector. The function of each of these LEDs is detailed below:
All LEDs are located on the topside of the 4 Port 10/100/1000 Mbps Ethernet Switch.
LED
Indication
D1
Labeled ‘1.2V’, surface mount, located in the middle of the top edge of the board.
This LED is non-functional and does not need to be illuminated for the board to
function properly.
D2
(Green/Green)
A dual LED located on the top edge of the board next to the optical module. The
top LED, labeled PWR, provides an indication that the power supply to the optical
transceiver is operational. The lower LED, labeled FBR, indicates that the optical
transceiver module has detected the presence of an input signal on the fiber link.
When ‘ON’ indicates that this board has a good level of received optical power
from the remote unit.
D3
(Green/Green)
A dual LED located on the top edge of the board next to the optical module. The
top LED, labeled LNK, provides an indication that the onboard MAC and PHY
are communicating properly. The lower LED, labeled DUP, should be
illuminated at all times to indicate that the optical link is functioning in full duplex
mode.
D4
(Green/Green)
A dual LED located in the upper left corner of the board next to the RJ-45
Ethernet connector. The top LED, labeled DUP1, is illuminated if Port 1 of the
Ethernet Switch is connected in full duplex mode. The lower LED, labeled
DUP3, is illuminated if Port 3 of the Ethernet Switch is connected in full duplex
mode.
D5
(Green/Green)
A dual LED located in the upper left corner of the board next to the RJ-45
Ethernet connector. The top LED, labeled DUP2, is illuminated if Port 2 of the
Ethernet Switch is connected in full duplex mode. The lower LED, labeled
DUP4, is illuminated if Port 4 of the Ethernet Switch is connected in full duplex
mode.
D7 (Green)
Labeled ‘2.5V’, surface mount, located on the mid-right of the board. When ‘ON’
indicates the on-board 2.5V converter is operational
D8 (Green)
Surface mount, located in the middle of the bottom edge of the board. Indicates
that power is being delivered to the Display Board Header (J7).
