The J11A/B connector supplies the 10Base-T, 100Base-TX and 1000Base-T interfaces to the
Ethernet controller.
Ethernet LED Status
ACT (green):
This LED monitors network connection and activity. The LED lights up when a
valid link (cable connection) has been established. The LED goes temporarily off if network
packets are being sent or received through the RJ-45 port. When this LED remains off, a valid
link has not been established due to a missing or a faulty cable connection.
SPEED (green/orange):
This LED lights up to indicate a successful 100Base-TX or
1000BASE-T connection. When green it indicates a 100Base-TX connection and when orange
it indicates a 1000Base-T connection. When not lit and the ACT-LED is active, the connection
is operating at 10Base-T.
