Performing a Site Survey
Before you mount and deploy your access point, we recommend that you perform a site survey (or use
a site planning tool) to determine the best location to install your access point.
You should have the following information about your wireless network available:
•Access point locations.
•Access point mounting options: below a suspended ceiling, on a flat horizontal surface, or on a
desktop.
Note You can mount the access point above a suspended ceiling but you must purchase
additional mounting hardware: See the “Mounting the Access Point” section on page 9
for additional information.
•Access point power options: power supplied by a DC power supply, PoE from a network device,
or a PoE power injector/hub (usually located in a wiring closet).
Note Access points mounted in a building’s environmental airspace must be powered using PoE
to comply with safety regulations.
Cisco recommends that you make a site map showing access point locations so that you can record the
device MAC addresses from each location and return them to the person who is planning or managing
your wireless network.
4 Obtaining and Assigning an IP Address
To browse to the access point Express Setup page, you must either obtain or assign the access point IP
address using one of these methods:
Note The access point does not have a default IP address.
•Assign a static IP address by connecting to its console port and accessing the access point CLI.
•Use a DHCP server (if available) to automatically assign an IP address. You can find out the
DHCP-assigned IP address by using one of the following methods:
– Connect to the access point console port and use a Cisco IOS command to display the IP
address, such as show interface bvi1.

7
– Provide your organization’s network administrator with your access point MAC address.
Your network administrator will query the DHCP server using the MAC address to identify
the IP address. The MAC address is on a label attached to the bottom of the access point.
– Use the CLI and serial port to identify the assigned IP address.
Connecting to the Access Point Locally
If you need to configure the access point locally (without connecting it to a wired LAN), you can
connect a PC to its console port by using a DB-9 to RJ-45 serial cable.
Caution Be careful when handling the access point, the bottom plate might be hot.
Follow these steps to open the CLI by connecting to the access point console port:
Step 1 Connect a nine-pin, female DB-9 to RJ-45 serial cable to the RJ-45 console port on the access
point and to the COM port on a computer.
Note The Cisco part number for the serial cable is AIR-CONCAB1200.
Step 2 Set up a terminal emulator on your PC to communicate with the access point. Use the
following settings for the terminal emulator connection: 9600 baud, 8 data bits, no parity, 1
stop bit, and no flow control.
Assigning the IP Address to the BVI
When you assign an IP address to the access point by using the CLI, you must assign the address to
the bridge-group virtual interface (BVI). Beginning in a privileged EXEC mode, follow these steps to
assign an IP address to the access point BVI using the access point console port.
Command Purpose
Step 1 configure terminal Enter global configuration mode.

8
Assigning an IP Address Using the CLI
Follow these steps to access the CLI using a Telnet session. These steps are for a PC running Microsoft
Windows with a Telnet terminal application. Check your PC operating instructions for detailed
instructions.
Step 1 Select Start > Programs > Accessories > Telnet.
If Telnet is not listed in your Accessories menu, select Start > Run, type Telnet in the entry
field, and press Enter.
Step 2 When the Telnet window appears, click Connect and select Remote System.
Step 3 In the Host Name field, type the access point IP address and click Connect.
Note If you are connected to the access point using a Telnet session, you lose your connection to
the access point when you assign a new IP address to the BVI. If you need to continue
configuring the access point using Telnet, use the new IP address to open another Telnet
session to the access point.
Step 2 interface bvi1 Enters interface configuration mode for the
BVI.
Step 3 ip address ip_address net_mask Assigns an IP address and subnet mask
address to the BVI.
Command Purpose

5 Mounting the Access Point
Cisco Aironet 3500, 1260, 1140, 1130, and 1040 series access points can be mounted in several
configurations, including on a suspended ceiling, on a hard ceiling or wall, on an elecrtical or network
box, and above a suspended ceiling. Click this URL to browse to complete access point mounting
instructions:
http://www.cisco.com/en/US/docs/wireless/access_point/mounting/guide/apmount.html
Note The integrated antenna design of the 1140 series access point is designed for horizontal
surfaces, (table top and ceiling installations). When mounted to such surfaces, the integrated
antennas produce the best antenna radiation pattern. For advanced features such as voice,
location, and rogue access point detection, ceiling mounting is strongly recommended.
However, for smaller areas such as conference rooms, kiosks, transportation, and hot-spot
usage where the customer is concerned primarily with data coverage and not advanced
features, you can mount the unit on a wall using wall anchors.
Caution Do not use plastic wall anchors or the keyhole slots on the mounting bracket for ceiling
installations. When mounting the access point on a hard ceiling, use four fasteners
capable of maintaining a minimum pullout force of 20 lbs (9 kg).
6 Configuring Basic Settings
Before you can configure basic settings, the access point and your PC needs an IP address. See the
“Obtaining and Assigning an IP Address” section on page 6.
Follow these steps to configure basic settings for the access point using the GUI Express Setup page.
Step 1 Open your browser, and enter the access point IP address in the address field. A username and
password screen appears.
Step 2 Enter the username Cisco and password Cisco. The username and password are case sensitive.
Step 3 Press Enter. The Summary Status page appears.

Step 4 If required, configure the power settings as described in the previous section. Otherwise, Click
Express Setup. The Express Setup page appears.
