Board Handling Precautions
To prevent damage due to Electrostatic Discharge (ESD), keep your board in its antistatic bag until you are ready to install it into your system.
When removing it from the bag, hold the board at the edges, and do not touch the components or connectors. Handle the board in an antistatic
environment, and use a grounded workbench for testing and handling of your hardware.

Link and Activity LEDs
Link and activity LEDs are provided on the edges of the RJ45 connectors. The LEDs provide status information. Each is a green LED. When
the link is established, the green Link LED will illuminate on the right side of the RJ-45 connector. When there is activity on that port the green
Activity LED will blink.
