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.

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
