Cisco Cisco Aironet 701e Access point Guía De Instalación

Connect and power up the access point.

Observe the access point LED.

When you power up the access point, it begins a power-up sequence that you can verify by 
observing the access point LED. If the power-up sequence is successful, the discovery and join 
process begins. During this process, the LED blinks sequentially green, red, and off. When the 
access point has joined a controller, the LED is green if no clients are associated or blue if one 
or more clients are associated.

If the LED is not on, the access point is most likely not receiving power.

If the LED blinks sequentially for more than 5 minutes, the access point is unable to find its 
primary, secondary, and tertiary Cisco wireless LAN controller. Check the connection 
between the access point and the Cisco wireless LAN controller, and be sure the access point 
and the Cisco wireless LAN controller are either on the same subnet or that the access point 
has a route back to its primary, secondary, and tertiary Cisco wireless LAN controller. Also, 
if the access point is not on the same subnet as the Cisco wireless LAN controller, be sure that 
there is a properly configured DHCP server on the same subnet as the access point, or that 
DNS resolution is available. See the 

 for additional information.

Use the ip helper address command to forward DHCP requests to a DHCP server on a 
different subnet. Click this URL for more information on the ip helper address command: 

Reconfigure the Cisco wireless LAN controller so that it is not the Master. 

A Master Cisco wireless LAN controller should be used only for configuring access 
points and not in a working network. 

If you experience difficulty getting your access point installed and running, look for a solution to your 
problem in this guide or in additional access point documentation. These, and other documents, are 
available on Cisco.com.
