Cisco Access Point LED Status
Checking the Lightweight Access Point LEDs
If your lightweight access point is not working proberly, you can check the Status, Ehternet, and Radio LEDs.
To see quickly the LED status and there meanings, use the following table to get a brief overview.
Table – LED Signals (1240 series)
|Message type||Ethernet LED||Radio LED||Status LED||Meaning|
|Boot loader status||Green||Green||Green||DRAM memory test ok.|
|Off||Blinking green||Blue-green||Initialize Flash file system|
|Off||Green||Pink||Flash memory test ok.|
|Green||Off||Dark blue||Ethernet test ok.|
|Green||Green||Green||Starting Cisco IOS.|
|Association status||—||—||Light green||Normal operating condition, but no wireless client devices are
associated with the unit.
|—||—||Blue||Normal operating condition, at least one wireless client device
is associated with the unit.
|Operating status||Green||—||—||Ethernet link is operational.|
|Blinking green||—||—||Transmitting or receiving Ethernet packets.|
|—||Blinking green||—||Transmitting or receiving radio packets.|
|Software upgrade in progress|
|Slow blinking green||—||—||Hybrid-REAP standalone mode|
|Boot loader warnings||Off||Off||Yellow||Ethernet link not operational.|
|Amber||Off||Yellow||Configuration recovery in progress
(Mode button pressed for 2 to 3 seconds).
(Mode button pressed for 20 to 30 seconds)
|Blinking green||Blinking red||Blinking pink||Image recovery in progress and Mode button is released.|
|Boot loader errors||Red||Red||Red||DRAM memory test failure.|
|Off||Red||Blinking red and blue||Flash file system failure.|
|Off||Amber||Blinking red and blue-green||Environment variable (ENVAR) failure.|
|Amber||Off||Blinking red and yellow||Bad MAC address.|
|Red||Off||Blinking red and off||Ethernet failure during image recovery.|
|Amber||Amber||Blinking red and off||Boot environment error.|
|Red||Amber||Blinking red and off||No Cisco IOS image file.|
|Amber||Amber||Blinking red and off||Boot failure.|
|Cisco IOS errors||Blinking amber||—||—||Transmit or receive Ethernet errors|
|—||Blinking amber||—||Maximum retries or buffer full occurred on the radio.|
|Red||Red||Amber||Software failure; try disconnecting and reconnecting unit power.|
|—||—||Amber||General warning, insufficient inline power (see the Low Power Condition for Lightweight Access Points section).|
|Controller status||Alternating green, red , and amber1||Connecting to the controller.
Note: If the access point remains in this mode for more than five minutes, the access point is unable to find the controller. Ensure a DHCP server is available or that controller information is configured on the access point.
|Green||Green||Blinking dark blue||Loading the access point image file.|
1This status indication has the highest priority and overrides other status indications.
