Interpreting the LED Display
The LED indicators on the front and rear of the router give you a visual clue to the router’s activity. When
the router is configured and working correctly and its power is cycled, the seven front panel LEDs each
briefly turn on/off in a “walking” pattern sequencing from the bottom to the top and back to the bottom.
The following table shows the possible states indicated by the LEDs. If the LEDs indicate a problem, refer
to the “Resolving Specific Issues” section later in this chapter.
