J5 | DATA, J6 | DATA Connections, RJ-45F

It is strongly suggested that the user does NOT mix products of
different speeds (e.g., 10BaseT on J5, 100BaseT on J6, and GigE on
J7), or different duplex operation (e.g., half duplex on J5 and full
duplex on J7), as this may cause a degradation in speed/performance

of the data link traffic.
The typical connector pinout is as follows:

The J5 | DATA and J6 | DATA connections are RJ-45 female auto-sensing,
auto-crossover ports used for 10/100/1000 BaseT Gigabit Ethernet data traffic.
Each port features two LEDs that provide the following operational indicators:
•
LED 1 (left-hand):
o Green = 1000 Mbit activity (GigE) detected;
o Amber = 100 Mbit activity detected;
o Off = 10 MBit activity detected.
•
LED 2 (right-hand):
o Yellow = Link detected;
o Blinking Yellow = Activity detected;
o Off = No Link detected.
