LED Patterns on Cisco Access Points

Resolution

If your access point is not communicating, check the three LED indicators on the top panel. You can use them to assess the unit's status quickly.

The LEDs signals have the following meanings (for additional details refer to Table:

•The Ethernet LED signals traffic on the wired LAN, or Ethernet infrastructure. This LED is normally green when an Ethernet cable is connected, and blinks green when a packet is received or transmitted over the Ethernet infrastructure. The LED is off when the Ethernet cable is not connected.

•The status LED signals operational status. Steady green indicates that the access point is associated with at least one wireless client. Blinking green indicates that the access point is operating normally but is not associated with any wireless devices.

•The radio LED blinks green to indicate radio traffic activity. The light is normally off, but it blinks green whenever a packet is received or transmitted over the access point's radio.
