Step5 If your access point does not indicate normal operation, turn it off and repeat the
pre-installation configuration.
Note 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.)
8 Mounting the Access Point
Cisco Aironet 2702 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:

9 Deploying the Access Point on the Wireless Network
After you have mounted the access point, follow these steps to deploy it on the wireless network:
Step1 Connect and power up the access point.
Step2 Observe the access point LED (for LED descriptions, see “Checking the Access Point LED”
section on page 18).
a. 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.
b. If the LED is not on, the access point is most likely not receiving power.
