Installation and Configuration

8. If everything works (the GREEN LED is on and the RED LED is off), reboot the Cisco Aironet 1000
Series lightweight access point and install it as described in this
document. If your Cisco Aironet 1000 Series lightweight access point fails this visual test, refer to
the
lightweight access points.
When you are installing a Cisco 1030 remote edge lightweight access point or a Layer 3 Cisco Aironet
Note
1000 Series lightweight access point on a different subnet than the Cisco Wireless LAN Controller, BE
SURE that a DHCP server is available on the subnet where you will be installing the Cisco Aironet 1000
Series lightweight access point and that the subnet has a route back to the Primary, Secondary, and
Tertiary Cisco Wireless LAN Controller. Ensure that the route back to the Cisco Wireless LAN
Controller has destination UDP ports 12222 and 12223 open for LWAPP communications. Ensure the
route back to the Primary, Secondary, and Tertiary Cisco Wireless LAN Controller allows IP packet
fragments. Finally, be sure that if address translation is used, the Cisco Aironet 1000 Series lightweight
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.)
9. When you have installed and powered up the Cisco Aironet 1000 Series lightweight access point in
its final destination, verify that the LEDs are in the same state they were in at the end of Step 7.

From the CLI, Web User Interface or Cisco WCS interface, configure the Cisco Aironet 1000
Series lightweight access point with its Primary, Secondary, and Tertiary Cisco Wireless LAN
Controller names (any of which can be the name of the configuring Cisco Wireless LAN
Controllers).
If required, use the CLI, Web User Interface or Cisco WCS interface to customize the Cisco
Aironet 1000 Series lightweight access point-specific 802.11a, 802.11b and 802.11g network
settings. Once again, the two YELLOW LEDs indicate the states of the 802.11a and 802.11b/g
networks. If any part of the network is disabled, the corresponding YELLOW LED remains off.

If no LEDs are on, the Cisco Aironet 1000 Series lightweight access point is most likely not
receiving power.
If the LEDs blink sequentially for more than five minutes, the Cisco Aironet 1000 Series
lightweight access point is unable to find its Primary, Secondary, or Tertiary Cisco Wireless
LAN Controller. Check the connection between the Cisco Aironet 1000 Series lightweight
access point and the Cisco Wireless LAN Controller, and be sure that they are either on the same
subnet or that the Cisco Aironet 1000 Series lightweight access point has a route back to its
Primary, Secondary, and Tertiary Cisco Wireless LAN Controllers.
Note that the Cisco 1030 remote edge lightweight access points at each remote location must be
on the same subnet to allow client roaming. Also, if the Cisco Aironet 1000 Series lightweight
access point is not on the same subnet as the Cisco Wireless LAN Controller, be sure that a
DHCP server is accessible on the same subnet as the Cisco Aironet 1000 Series lightweight
access point.
