Interpreting Port-Side LEDs

After you install the network cables, you can observe certain LEDs to determine if the network connections are functioning.

The following figures and tables outline the state of each LED, the status of the hardware, and any recommended action.

Note: The illustrations are somewhat truncated to show all LEDs.
