Installation and Configuration
If everything works (the GREEN LED is on and the RED LED is off), disconnect the AP and take it to
Step 5
its final destination and install it as described later in this document. If your AP fails this visual test, refer
to
"Obtaining Technical
When you are installing a Layer 3 AP on a different subnet than the Cisco Wireless LAN Controller, BE
Note
SURE that a DHCP server is available on the subnet where you will be installing the AP, 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 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, that the AP and
the Cisco Wireless LAN Controller have a static 1-to-1 NAT to an outside address. (Port Address
Translation is not supported.)
When you have installed and powered up the AP in its final destination, verify that the LEDs are in the
Step 6
same state they were in at the end of Step 4. If no LEDs are on, the AP is most likely not receiving power.
If all the LEDs blink sequentially for more than five minutes, the AP is unable to find its Primary,
Secondary, and Tertiary Cisco Wireless LAN Controller. Check the connection between the AP and the
Cisco Wireless LAN Controller, and be sure the AP and the Cisco Wireless LAN Controller are either
on the same subnet or that the AP has a route back to its Primary, Secondary, and Tertiary Cisco Wireless
LAN Controller. Also, if the AP is not on the same subnet as the Cisco Wireless LAN Controller, be sure
there is a DHCP server on the same subnet as the AP.
After you have prepared all APs, reconfigure the Cisco Wireless LAN Controller so it is not the Master.
Step 7
A Master Cisco Wireless LAN Controller should only be used for configuring APs and not in a working
network. Note that the Master Cisco Wireless LAN Controller is normally not used in a deployed
network, so the Master Cisco Wireless LAN Controller setting is automatically disabled upon reboot or
OS upgrade.

Preparing Mounting Locations
On your map, you should have the AP locations, mounting options, and power options.
BE SURE that plenum-mounted APs use only the metal Projection-Mount and Flush-Mount brackets
Note
(not the Ceiling-Mount Base or the Hanging-Ceiling Clips) and are powered using PoE to comply with
safety regulations.

"Pre-Installation
Find the required mounting locations and prepare them in one of these ways:
Use the ceiling-mount base to mark the wall or ceiling locations for sheet metal, drywall, or
–
other screws. Be sure you leave enough space around the AP and base to plug the CAT-5 cable,
optional power supply cable, and optional Kensington MicroSaver Security Cable into the sides
of the AP.
