1.4 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 Mb s Ethernet Switch. In addition, there are 8 LED indicators that are built into the 4
osition RJ-45 connector. The function of each of these LEDs is detailed below:
All LEDs are located on the to side of the 4 Port 10/100/1000 Mb s Ethernet Switch.
LED Indication
D1
Labeled ‘1.2V’, surface mount, located in the middle of
the to edge of the board.
This LED is non-functional and does not need to be illuminated for the board to
function ro erly.
D2
(Green/Green)
A dual LED located on the to edge of the board next to the o tical module. The
to LED, labeled PWR, rovides an indication that the ower su ly to the o tical
transceiver is o erational. The lower LED, labeled FBR, indicates that the o tical
transceiver module has detected the resence of an in ut signal on the fiber link.
When ‘ON’ indicates that this board has a good level of received o tical ower
from the remote unit.
D3
(Green/Green)
A dual LED located on the to edge of the board next to the o tical module. The
to LED, labeled LNK, rovides an indication that the onboard MAC and PHY
are communicating ro erly. The lower LED, labeled DUP, should be
illuminated at all times to indicate that the o tical link is functioning in full du lex
mode.
D4
(Green/Green)
A dual LED located in the u er left corner of the board next to the RJ-45
Ethernet connector. The to LED, labeled DUP1, is illuminated if Port 1 of the
Ethernet Switch is connected in full du lex mode. The lower LED, labeled
DUP3, is illuminated if Port 3 of the Ethernet Switch is connected in full du lex
mode.
D5
(Green/Green)
A dual LED located in the u er left corner of the board next to the RJ-45
Ethernet connector. The to LED, labeled DUP2, is illuminated if Port 2 of the
Ethernet Switch is connected in full du lex mode. The lower LED, labeled
DUP4, is illuminated if Port 4 of the Ethernet Switch is connected in full du lex
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 o erational
D8 (Green) Surface mount, located in the middle of the bottom edge of the board. Indicates
that ower is being delivered to the Dis lay Board Header (J7).
