Overview
The Cisco Aironet 1200 Series Access Point (hereafter called the access point) delivers a cost-effective,
reliable, secure, and easily managed wireless LAN solution for enterprise customers and for small and
medium sized businesses. The access point is designed to incorporate new technology enhancements as
they become available.
The access point can contain one or two wireless LAN transceivers (radios). Each transceiver serves as
the center point of a stand-alone wireless network or as the connection point between wireless and wired
networks. In large installations, wireless users within radio range of an access point can roam throughout
a facility while maintaining uninterrupted access to the network.
The access point can support simultaneous dual-band (2.4-GHz and 5-GHz) radio operation or
single-band (2.4-GHz only or 5-GHz only) radio operation. Single-band radio units can be
field-upgraded for dual-band radio operation through the addition of a 5-GHz radio module or a 2.4-GHz
radio card.
Note The access point is IEEE 802.11b compliant when configured with the 2.4-GHz radio and is
IEEE 802.11a compliant when configured with the 5-GHz radio module.

Dual-Band Radio Support
The access point can be initially configured from the factory for single- or dual-band radio operation.
However, an access point configured for single-band radio operation can be field-upgraded to support
dual-band radio operation using the 5-GHz radio module or the 2.4-GHz mini-PCI radio card.
2.4-GHz Mini-PCI Radio Card
The 2.4-GHz mini-PCI radio card connects to an internal access point mini-PCI slot. The radio card
contains a wireless LAN transceiver that operates in the 2.4-GHz frequency range to provide the access
point with single- or dual-band radio capability.
5-GHz Radio Module
The 5-GHz radio module connects to the access point’s card bus connector. The module incorporates an
Unlicensed National Information Infrastructure (UNII) radio transceiver operating in two of the UNII
5-GHz frequency bands and supporting up to 8 channels:
• UNII 1—Frequency range is 5.15 to 5.25 GHz
• UNII 2—Frequency range is 5.25 to 5.35 GHz

OL-7043-02
Chapter 1 Overview
Key Features
The module contains dual integrated omnidirectional antennas and directional patch antennas for
diversity operation.
Power
The access point can receive power through an external power module or through inline power using the
Ethernet cable. Using inline power, you do not need to run a separate power cord to the access point.
Plug the Ethernet cable into the Ethernet port on the back of the access point and plug the other end into
one of the inline power sources. The access point supports the following power sources:
• Inline power
–
A 1200 series power injector
–
A switch with inline power, such as the Cisco Catalyst 3524-PWR-XL switch
–
An inline power patch panel, such as the Cisco Catalyst Inline Power Patch Panel
• A 1200 series power module (Universal power supply)
Caution The 1200 series power injectors are designed for use with Cisco Aironet 1200 Series Access Points only.
Using the power injector with other Ethernet-ready devices can damage the equipment.
Caution The 1200 series power injectors are not tested to UL 2043 and should not be placed in a building’s
environmental air space, such as above suspended ceilings.
Note Only the 1200 series power injector and the 1200 series power module can support operation of the
5.0-GHz radio in the access point.
Note If you need to use a power module or power injector to power the access point, you must use the 1200
series power module or power injector. The 350 series power module and power injector are not
compatible with the 1200 series access point.
Note When using in-line power from a switch or patch panel do not connect the 1200 series power module to
the access point. Using two power sources on the access point might cause the switch or patch panel to
shut down the port to which the access point is connected.
Note Both the Ethernet and console ports use RJ-45 connectors. Be careful not to accidently connect the
Ethernet cable to the console port connector.

Cisco Aironet 1200 Series Access Point Hardware Installation Guide, OL-2155-02
OL-7043-02
Chapter 1 Overview
Key Features
Antenna Connectors
The access point supports two antenna connectors on the back of the unit for the 2.4-GHz radio. The
5-GHz radio supports only integrated antennas.
2.4-GHz Radio
The access point provides two reverse-polarity TNC (R-TNC) connectors that you can use to connect a
single antenna or dual diversity antennas to provide coverage for your wireless LAN area. Diversity
coverage helps maintain a clear radio signal between the access point and wireless client devices. Just
as you can improve signal clarity on your car radio at a stoplight by creeping ahead a few inches, the
access point can improve signal quality by choosing the antenna that is receiving the best signal from a
client device.
Ethernet and Console Ports
Ethernet Port
The Ethernet port accepts an RJ-45 connector, linking the access point to your 10BASE-T or
100BASE-T Ethernet LAN. The access point can receive power through the Ethernet cable from a switch
with inline power, from a power patch panel, or from the access point’s 1200 series power injector.
Console Port
The console port provides access to the access point’s management system using a terminal emulator
program. Use an RJ-45 to DB-9 serial cable (refer to Appendix C, “Console Cable Pinouts”) to connect
your computer’s COM port to the access point’s serial console port. Assign the following port settings
to a terminal emulator to open the management system pages: 9600 baud, 8 data bits, No parity, 1 stop
bit and no flow control.
Metal Enclosure
The access point uses a metal enclosure having adequate fire resistance and low smoke-producing
characteristics suitable for operation in a building’s environmental air space in accordance with Section
300-22(c) of the NEC, such as above suspended ceilings. The access point also supports an industrial
temperature operating range (refer to Access Point Specifications, page 1-10).
Note If you plan to mount the access point in environmental air space using a 5-GHz radio, Cisco recommends
that you mount the access point horizontally with its antennas pointing down. Doing so results in the
access point complying with regulatory requirements for environmental air space with the 5-GHz radio
installed.

Chapter 1 Overview
Key Features
Indicators
The three indicators on top of the access point report Ethernet activity, association status, and radio
activity as shown in Figure 1-1.
Figure 1-1 Indicators on the 1200 Series Access Point
•
The Ethernet indicator signals Ethernet traffic on the wired LAN. This indicator blinks green when
a packet is received or transmitted over the Ethernet infrastructure. The indicator is off when the
Ethernet cable is not connected.
• The association status indicator signals operational status. Blinking green indicates that the access
point is operating normally but is not associated with any wireless client devices. Steady green
indicates that the access point is associated with at least one wireless client device.

Key Features
Security Lock Feature
The access point provides two methods of securing the access point to help prevent theft (see
Figure 1-2):
• Security hasp
• Security cable keyhole
The security hasp on the mounting bracket enables you to lock the access point to the bracket to make it
more secure. When the access point is properly installed on the mounting bracket, the holes in the
security hasps line up so you can install a padlock. Compatible padlocks are Master Lock models 120T
or 121T.
When using the security hasp with a lock, the access point is secured to the mounting bracket and the
mounting bracket screws along with the 2.4-GHz radio access cover are not accessible.
The security cable keyhole allows you to secure the access point using a standard security cable, such as
the security cables used on laptop computers.

Network Configuration Examples
Network Configuration Examples
This section describes the access point’s role in three common wireless network configurations. The
access point’s default configuration is as a root unit on a wired LAN. The other two possible roles,
repeater unit and central unit in an all-wireless network, require specific changes to the default
configuration.
Note The following network configuration examples apply to both 2.4-GHz and 5-GHz wireless LANs.
Root Unit on a Wired LAN
An access point connected directly to a wired LAN provides a connection point for wireless users. If
more than one access point is connected to the LAN, users can roam from one area of a facility to another
without losing their connection to the network. As users move out of range of one access point, they
automatically connect to the network (associate) through another access point. The roaming process is
seamless and transparent to the user. Figure 1-3 shows access points acting as root units on a wired LAN.

Repeater Unit That Extends Wireless Range
An access point can be configured as a stand alone repeater to extend the range of your infrastructure or
to overcome an obstacle that blocks radio communication. The repeater forwards traffic between
wireless users and the wired LAN by sending packets to either another repeater or to an access point
connected to the wired LAN. The data is sent through the route that provides the greatest performance
for the client. Figure 1-4 shows an access point acting as a repeater.

Central Unit in an All-Wireless Network
In an all-wireless network, an access point acts as a stand-alone root unit. The access point is not
attached to a wired LAN; it functions as a hub linking all stations together. The access point serves as
the focal point for communications, increasing the communication range of wireless users. Figure 1-5
shows an access point in an all-wireless network.

Installation Guidelines
Installation Guidelines
This section describes things to keep in mind when installing your access point. Sections include:
• Basic Guidelines
• Installation Above Suspended Ceilings
• Coverage Options
• Site Surveys
Basic Guidelines
Because the access point is a radio device, it is susceptible to common causes of interference that can
reduce throughput and range. Follow these basic guidelines to ensure the best possible performance:
• Install the access point in an area where large steel structures such as shelving units, bookcases, and
filing cabinets do not obstruct radio signals to and from the access point.
• Install the access point away from microwave ovens. Microwave ovens operate on the same
frequency as the access point and can cause signal interference.
Installation Above Suspended Ceilings
The access point uses a metal enclosure having adequate fire resistance and low smoke-producing
characteristics suitable for operation in a building’s environmental air space in accordance with
Section 300-22(c) of the NEC, such as above suspended ceilings. For mounting instructions refer to
Chapter 4, “Mounting Instructions.”
Caution The 1200 series power injectors are not tested to UL 2043 and should not be placed in a building’s
environmental air space, such as above suspended ceilings.
Note If you plan to mount the access point in environmental air space using a 5-GHz radio, Cisco recommends
that you mount the access point horizontally with its antennas pointing down. Doing so will result in the
access point complying with regulatory requirements for environmental air space with the 5-GHz radio
installed.

Installation Guidelines
Coverage Options
The network architecture options of wireless stations and access points provide for a variety of coverage
alternatives and flexibility. The network can be designed to provide a wide coverage area with minimal
overlap or a narrow coverage area with heavy overlap. A narrow coverage area with heavy overlap
improves network performance and protection against downtime if a component fails.
Note The following coverage options apply to both 2.4-GHz and 5-GHz wireless LANs.
Minimal Overlap Coverage Option
By arranging the access points so that the overlap in a coverage area is minimized, a large area can be
covered with minimal cost (see Figure 2-1). The total bandwidth available to each wireless client device
depends on the amount of data each mobile station needs to transfer and the number of stations located
in each cell. Seamless roaming is supported as a client device moves in and out of range of each access
point, thereby maintaining a constant connection to the wired LAN. Each device in the radio network
must be configured with the same SSID to provide roaming capability.
Figure 2-1 Minimal Overlap Coverage Option
Heavy Overlap Coverage Option
By arranging the access points so the overlap in coverage area is nearly maximized, a large number of
mobile stations can be supported in the same wireless infrastructure. However, devices in overlapping
coverage areas on the same frequency detect adjacent cell traffic and delay transmissions that would
cause collisions. This configuration reduces the aggregate radio system throughput. Heavy cell overlap
is not recommended for maximum system throughput.

Chapter 2 Installation
Unpacking the Access Point
Because of the redundancy in coverage overlap, network access is not lost if an access point fails. Upon
failure of the access point, the station automatically roams to an operational access point. With this
architecture, each device in the RF network must be configured with the same SSID to provide the
roaming capability.
Site Surveys
Because of differences in component configuration, placement, and physical environment, every
network application is a unique installation. Before installing multiple access points, you should perform
a site survey to determine the optimum utilization of networking components and to maximize range,
coverage, and network performance.
When supporting dual mode 2.4-GHz and 5-GHz operation, you may have to perform a site survey for
each of the operating frequencies.
Consider the following operating and environmental conditions when performing a site survey:
• Frequency—The radio coverage area for the 5-GHz radio is less than the coverage area for the
2.4-GHz radio.
• Single- and dual-band operation—When supporting both single- and dual-band access points, you
should perform a site survey for each of the operating frequencies.
• Data rates—Sensitivity and range are inversely proportional to data bit rates. The maximum radio
range is achieved at the lowest workable data rate. A decrease in receiver threshold sensitivity occurs
as the radio data increases.
• Antenna type and placement—Proper antenna configuration is a critical factor in maximizing radio
range. As a general rule, range increases in proportion to antenna height.
• Physical environment—Clear or open areas provide better radio range than closed or filled areas.
Also, the less cluttered the work environment, the greater the range.
• Obstructions—A physical obstruction such as metal shelving or a steel pillar can hinder
performance of wireless devices. Avoid locating the devices in a location where there is a metal
barrier between the sending and receiving antennas.
• Building materials—Radio penetration is greatly influenced by the building material used in
construction. For example, drywall construction allows greater range than concrete blocks. Metal or
steel construction is a barrier to radio signals.
Unpacking the Access Point
Follow these steps to unpack the access point:
Step 1 Open the shipping container and carefully remove the contents.
Step 2 Return all packing materials to the shipping container and save it.
Step 3 Ensure that all items listed in the “Package Contents” section are included in the shipment. Check each
item for damage. If any item is damaged or missing, notify your authorized Cisco sales representative.
