Apply power to the access point:

The access point is 802.3af (15.4 W) compliant and can be powered by any 
802.3af-compliant device.

The access point is downgraded to 3x3 when it is connected to a 15.4W supply. For the 
access point to operate at its full potential, using an 802.3at PoE switch or AIR-PWRINJ4 
power injector is recommended.

The recommended external power supply for the access point is the Cisco AIR-PWR-B 
power supply. The access point can also be powered by the following optional external 
power sources: 

Access point power injector (AIR-PWRINJ5)

Any 802.3af or 802.3at compliant power injector

The 3702 series access point requires a Gigibit Ethernet link to prevent the Ethernet 
port from becoming a bottleneck for traffic because wireless traffic speeds exceed 
transmit speeds of a 10/100 Ethernet port.

As the access point attempts to connect to the controller, the LEDs cycle through a green, red, 
and amber sequence, which can take up to 5 minutes.

If the access point remains in this mode for more than five minutes, the access point is 
unable to find the Master Cisco wireless LAN controller. Check the connection between 
the access point and the Cisco wireless LAN controller and be sure that they are on the 
same subnet. 

If the access point shuts down, check the power source.

After the access point finds the Cisco wireless LAN controller, it attempts to download the 
new operating system code if the access point code version differs from the Cisco wireless 
LAN controller code version. While this is happening, the Status LED blinks dark blue.

If the operating system download is successful, the access point reboots.

Configure the access point if required. Use the controller CLI, controller GUI, or Cisco Prime 
Infrastructure to customize the access-point-specific 802.11ac network settings.
