The integrated LEDs of the RJ45 connectors connect to the respective phys. See section 7.4.2
for more information on the LEDs displays.
7.5.3 On-board connectors
In this section, other on-board connectors that cannot be accessed from the front panel will be
discussed.
7.5.3.1 JTAG Connector
The JTAG connector is compatible with standard Xilinx USB platform cables, the pinout is shown
in the table below:
