Note Some older switches and patch panels might not provide enough
power to operate the access point. At power on, if the access point is
unable to determine that the power source can supply sufficient
power, the access point automatically deactivates both radios to
prevent an over-current condition. The access point also activates a
Status LED low power error indication and creates an error log entry.
See the Cisco Aironet 1240AG Series Access Point Hardware
Installation Guide for more information.
When power is applied to the access point, it begins a routine power-up
sequence that you can monitor by observing the three LEDs on the 2.4-GHz
end of the access point. After all three LEDs turn green to show the starting
of the Cisco IOS operating system, the Status LED blinks green to show that
Cisco IOS is operational. When in an operational status, the Ethernet LED is
steady green when no traffic is being passed and off when traffic is being
passed. The sequence takes about 1 minute to complete. Refer to the
"Checking the Access Point LEDs" section on page
When the sequence is complete, you are ready to obtain the access point IP
address and perform an initial configuration. Refer to
