Cisco Cisco Aironet 1700i Access Points 설치 가이드

If your access point does not indicate normal operation, turn it off and repeat the 
pre-installation configuration.

When you are installing a Layer 3 access point on a different subnet than the Cisco 
wireless LAN controller, be sure that a DHCP server is reachable from the subnet on 
which you will be installing the access point, and that the subnet has a route back to 
the Cisco wireless LAN controller. Also be sure that the route back to the Cisco 
wireless LAN controller has destination UDP ports 5246 and 5247 open for CAPWAP 
communications. Ensure that the route back to the primary, secondary, and tertiary 
wireless LAN controller allows IP packet fragments. Finally, be sure that if address 
translation is used, that the access point and the Cisco wireless LAN controller have 
a static 1-to-1 NAT to an outside address. (Port Address Translation is not 
supported.)

Cisco Aironet 1702 series access points can be mounted in several configurations, including on a 
suspended ceiling, on a hard ceiling or wall, on an electrical or network box, and above a suspended 
ceiling. Click this URL to browse to complete access point mounting instructions:

After you have mounted the access point, follow these steps to deploy it on the wireless network:

Connect and power up the access point.

Observe the access point LED (for LED descriptions, see 

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 chirping green if no clients are associated or 
green if one or more clients are associated.

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