Interpreting the LED Display

The LED indicators on the front of the router give you a visual clue to the router activity. When the router
is configured and working correctly, all LED indicator lights briefly turn a solid green. The following table
shows the possible states indicated by the LEDs. If the LEDs indicate a problem, refer to "Resolving
Specific Issues" later in this chapter.
