Quick Start Guide Cisco Aironet 1240AG Series Access Point
Read This First
Note If you purchased a 1242G access point, this quick start guide refers
occasionally to an 802.11a radio. However, your 1242G access point
does not contain an 802.11a radio; it only contains an 802.11b or
802.11g radio. Please disregard the sections in your quick start guide
that refer specifically to an 802.11a radio.
You should review this table and the instructions for opening the top cover.
The table contains important information that you need to know so that you
can successfully configure your access point.

Radio and IP Address Configuration
The access point ships with its radio disabled and no assigned IP address or
service set identifier (SSID). You must enable them when you configure the
access point for the first time. The access point no longer is assigned an IP
address. It is configured to obtain an IP address by using a DHCP server. If
your network does not use a DHCP server, you must connect to the access
point console port and assign a static IP address (See the “Assigning an IP
Address Using the CLI” section on page 20.
Status LED Status Description
Blue Normal operating condition and at
least one wireless client device is
associated with the access point.
Light green Normal operating condition, but no
wireless client devices are
associated with the access point.
Amber or red Error condition. See the “Checking
the Access Point LEDs” section on
page 42.

Quick Start Guide Cisco Aironet 1240AG Series Access Point
Before You Start
Before you install the access point, make sure that you are using a computer
connected to the same network as the access point, and obtain the following
from your network administrator:
•A host name for the access point
•The case-sensitive SSID for your radio 802.11g and 802.11a radio
networks
•A Simple Network Management Protocol (SNMP) community name and
the SNMP file attribute (if SNMP is in use)
•The Media Access Control (MAC) address from the label on the bottom
of the access point (such as 0016462584c), if you plan to use the Cisco
IP Setup Utility to find an access point IP address.
•If you are not connected to a DHCP server, you can assign an IP address
to the access point using the CLI. In this situation, obtain a unique IP
address for your access point, a default gateway, and subnet mask from
your network system administrator.

Safety Information
The FCC with its action in ET Docket 96-8 has adopted a safety standard for
human exposure to radio frequency (RF) electromagnetic energy emitted by
FCC certified equipment. When used with approved Cisco Aironet antennas,
Cisco Aironet products meet the uncontrolled environmental limits found in
OET-65 and ANSI C95.1, 1991. Proper installation of this radio according to
the instructions found in this manual will result in user exposure that is
substantially below the FCC recommended limits.
•Do not hold any component containing a radio so that the antenna is very
close to or touching any exposed parts of the body, especially the face or
eyes, while transmitting.
•The use of wireless devices in hazardous locations is limited to the
constraints posed by the safety directors of such environments.
Warnings
Translated versions of the following safety warnings are provided in
Appendix A of the Cisco Aironet 1240AG Series Access Point Hardware
Installation Guide.

Warning This product must be connected to a Power over Ethernet (PoE)
IEEE 802.3af compliant power source or an IEC60950 compliant
limited power source. Statement 353
The access point power options:
•Option 1—Switches with sufficient inline power:
– An inline power capable switch, such as the Catalyst 3550 PWR
XL, 3560-48PS, 3750-48PS, 4500 with 802.3af Power over
Ethernet module, or the 6500 with 802.3af Power over Ethernet
module
– Other inline power switches supporting the IEEE 802.af inline
power standard
•Option 2—Switches without sufficient inline power can use the power
injector:
– Cisco Aironet Power Injector (AIR-PWRINJ3 or
AIR-PWRINJ-FIB)
•Option 3—Local power using a power module

17
Quick Start Guide Cisco Aironet 1240AG Series Access Point
Note Some older switches and patch panels might not provide enough
power to operate the access point. At power on, if the access point is
unable to determine that the power source can supply sufficient
power, the access point automatically deactivates both radios to
prevent an over-current condition. The access point also activates a
Status LED low power error indication and creates an error log entry.
See the Cisco Aironet 1240AG Series Access Point Hardware
Installation Guide for more information.
When power is applied to the access point, it begins a routine power-up
sequence that you can monitor by observing the three LEDs on the 2.4-GHz
end of the access point. After all three LEDs turn green to show the starting
of the Cisco IOS operating system, the Status LED blinks green to show that
Cisco IOS is operational. When in an operational status, the Ethernet LED is
steady green when no traffic is being passed and off when traffic is being
passed. The sequence takes about 1 minute to complete. Refer to the
“Checking the Access Point LEDs” section on page 42for LED descriptions.
When the sequence is complete, you are ready to obtain the access point IP
address and perform an initial configuration. Refer to “Configuring Basic
Settings” section on page 25 for instructions on assigning basic settings to the
access point.

18
OL-16714-01
Note If your access point is connected to inline power, do not connect the
power module to the access point. Using two power sources on the
access point might cause the access point to shut down to protect
internal components and might cause the switch to shut down the
port to which the access point is connected. If your access point
shuts down, you must remove all power and reconnect only a single
power source.
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 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:

19
Quick Start Guide Cisco Aironet 1240AG Series Access Point
– 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 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:
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.

20
OL-16714-01
Note The Cisco part number for the serial cable is
AIR-CONCAB1200.
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 an IP Address Using the CLI
When you assign an IP address to the access point by using the CLI, you must
assign the address to the 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.
Step 2 Interface bvi1 Enters interface configuration mode
for the BVI.
Step 3 ip address address mask Assigns an IP address and subnet mask
address to the BVI.
