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 at horizontal surface, or on a
desktop.

22/09/2019 Getting Started Guide: Cisco Aironet 1140 Series Autonomous Access Point - Cisco
https://www.cisco.com/c/en/us/td/docs/wireless/access_point/1140/autonomous/getting_started/guide/ap1140aut_getstart.html 6/30
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 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 nd 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.
– 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 congure 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.

https://www.cisco.com/c/en/us/td/docs/wireless/access_point/1140/autonomous/getting_started/guide/ap1140aut_getstart.html 7/30
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 ow 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
congure terminal
Enter global conguration mode.
Step2
interface bvi1
Enters interface conguration mode for the BVI.
Step3
ip address ip_address
net_mask
Assigns an IP address and subnet mask address to
the BVI.
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
eld, and press Enter.
Step2 When the Telnet window appears, click Connect and select Remote System.
Step3 In the Host Name eld, 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
conguring the access point using Telnet, use the new IP address to open another Telnet
session to the access point.
5 Mounting the Access Point
Cisco Aironet 3500, 1260, 1140, 1130, and 1040 series access points can be mounted in several
congurations, 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

https://www.cisco.com/c/en/us/td/docs/wireless/access_point/1140/autonomous/getting_started/guide/ap1140aut_getstart.html 8/30
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 Conguring Basic Settings
Before you can congure basic settings, the access point and your PC needs an IP address. See
the "Obtaining and Assigning an IP Address" section.
Follow these steps to congure 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 eld. 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5 Congure the settings using the following sections as a guide.
• Host Name—The host name (or system name) is a name for the access point that identies it on
your network. The system name appears in the titles of the management system pages.
• Conguration Server Protocol—This setting species how the access point obtains an IP
address.
DHCP—IP address is automatically assigned by the network DHCP server.
Static IP—The access point uses a static IP address that you enter in the IP address
eld.
• IP Address—This setting assigns or changes the access point IP address. If DHCP is enabled,
the access point obtains its IP address from your network DHCP server. You can assign a static IP
address in this eld.
• IP Subnet Mask—The IP subnet mask identies the subnet on which the access point resides.
This subnet is provided by your network administrator. If DHCP is enabled, leave this eld blank.
• Default Gateway—The default gateway identies the address the access point uses to access
another network. This gateway is provided by your network administrator. If DHCP is enabled, leave
this eld blank.
• Web Server—This setting species the type of HTTP used to access the access point using a
web browser.
Standard (HTTP)—Standard protocol used to transfer HTML using unencrypted
trac between web browsers.
Secure (HTTPS)—Protocol used to transfer secure data by using encrypted trac to
and from the user by means of a Secure Socket Layer (SSL).
