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.
Each port features two LEDs that provide the following operational indicators:
LED
1 (left-hand)
2 (right-hand)
The typical connector pinout is as follows:
Pin #

The RJ‐45 female J5 | DATA and J6 | DATA connections are auto‐sensing,
auto‐crossover ports used for 10/100/1000 BaseT Gigabit Ethernet data traffic.
