The Cisco Aironet 1200 Series Access Point (hereafter called the access point) delivers a cost-effective,
reliable, secure, an d easily managed wi reless LAN solution for enterpr ise custome rs and fo r 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 s tand-al one wire less netw ork or as t he conne ction poin t between wire less and wir ed
networks. In large installations, wireless users within radio range of an access point can roam throughout
a facility while maintaining uninterrupted access to the netwo rk.

The access po int c an suppor t sim ultane ou s d ua l-ba nd (2 .4- G Hz and 5 -G Hz) radi o op er ati on or
single-band (2.4-G Hz only or 5-G Hz only ) r adi o ope rat ion. Singl e-b an d rad io u nit s c an b e

An inline power patch pa nel, s uch a s t he Ci sco C ata lyst Inl ine Power Patch Pa nel

• 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 Ethe rnet-r eady devices can da mage th e equipm ent.

Caution The 1200 series power injectors are not tested to UL 2043 and should not be placed in a building ’s

enviro nmental air space, such as above suspended ceilings.

Note Only the 1200 series power injec tor and th e 1200 seri es power module can support oper ation of the

5.0-GHz radio in th e a cce ss po int.

Note If you need to use a power module or power injector to power the acce ss point, you mu st use the 120 0

series power module or p ower inject o r. The 350 series power modul e a nd power inj ect or a re n ot
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. U s i ng two power sources on the access point might cause the switch or patch pa nel to
shut down the port to which the access point is conne cted.

Note Both the Ethernet and console ports use RJ-45 connectors. Be careful not to accidently connect the

Ethernet cable to t he cons ole port connect or.

single antenna or dual d iversity antenna s t o provi de c overage fo r you r w ire le ss LA N a rea. Diversity
coverage helps maintain a clear ra dio signa l betwee n the acces s point and w ireless cl ient 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 acce pts an RJ-45 co nnec tor, linking the access point to your 10BASE-T or
100BASE -T Ethern et LAN. The access point c an recei ve powe r through the Ethe rnet ca ble from a switch
with inline power, from a power patch panel, or from the access point’s 1200 ser ies power injector.

Console Port

The console port provides access to the access point’s management system using a termi nal e mula tor
program. Use an RJ- 4 5 to DB -9 s er ial cable (refer to Appendix C, “Console Cable Pinouts”) to connect
your computer’s COM port to the ac cess point’s serial consol e port. Assi gn the following port settings
to a terminal em ul ato r to op en the mana gem en t syste m p ages: 960 0 b au d, 8 dat a b its, No pa rit y, 1 stop
bit and no flow co ntro l.

Metal Enclosure

The access point uses a me tal encl osure having adequat e fire resistan ce and low smoke-pr oducing
characteristics suitable for oper ati on in a building’s environme nta l ai r s pace in accordance with Section
300-22(c) of the NEC, such as ab ove suspended ceiling s. The a ccess poi nt also suppo rts an indu strial
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.

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 bra cket enables you to lock the access point to the brac k e t to make it
more secure. When the access point is properly installed on the mounting bracket, the holes in th e
security hasps line up so you can install a pa dlock. 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 sc rews alon g w ith th e 2. 4-G Hz radi o a cce ss cover ar e not ac cessib le.

The security cable keyhole allows you to secure the access point using a standard security cable, such as

Network Configuration Examples

Network Configuration Examples

This section describes the access point ’s role in three commo n wireless networ k configurati ons. The
access point’s default configurati on is as a root unit on a w ired LAN. The other two possi ble roles,
repeater unit and central unit in an all-wireless network, require specific changes to the default
configuration.

Note The following network configurati on examples ap ply to both 2.4 -GH z and 5-GHz wireless LA Ns.

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 poi nt is connected to the LAN, users c an roam from one area of a fac ility to another
without losing thei r conn ect ion to t he ne twork. A s users move out o f range o f one a ccess poi nt, they
automatically con nect to the network (assoc iate) th rough anot her acces s point . The roami ng proce ss is
seamless and transparent to th e 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 ei ther an other repe ater or to an a ccess poi nt
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.

Basic Guidelines

Because the access point is a radio dev ice, it is susceptible to common causes of interference that can
reduce throughpu t a nd ra nge . Foll ow these b asic gu ide lin es t o ensu re the b es t pos sibl e perfo rm an ce:

• Install the acces s po int i n an a rea wher e lar g e st eel st ructu res s uch a s sh elving units , boo kcase s, an d

filing cabinets do no t ob struc t radi o sign als to a nd from the ac cess 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 me tal encl osure having adequat e fire resistan ce and low smoke-pr oducing
characteristics suitable for operation in a building’s env ironm ental air sp ace i n acco rdanc e wit h
Section 300-22(c) of the NE C, such as above suspende d ceilings. For mo unting inst ruction s refer to

Chapter 4, “Mo unting In structi ons.”

Caution The 1200 series power injectors are not tested to UL 2043 and should not be placed in a building ’s

enviro nmental 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 h orizonta lly with i ts antennas p ointing down. Doing so will result in the
access point complying with regulatory requirements for environmental air space with the 5-GHz radio
installed.

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 ar ea wit h heavy overla p. A na rrow coverage are a wi th h eavy overla p
improves network performance and pr otec ti on aga inst downtime if a c om ponent 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 ea ch mob ile stat ion ne eds to transfe r an d the num be r of stat ion s loca ted
in each cell. Seamless roaming is supported as a client device moves in and out of range of each access
point, thereby maintai ning a const ant con nection to the wi red LAN. Ea ch device in the ra dio 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 c an be supp orted in the sam e w irele ss infra stru ctur e. H owever, devices in overlapping
coverage areas on the same frequency det ect adjac ent cell tr affic and delay transmissi ons that woul d

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, eac h device in t he R F net work mu st b e c onfigur ed w it h th e sam e SSID to p rovide the
roaming capability.

Site Surveys

Because of differen ces i n comp one nt co nfigurati on, pla cem ent , an d physi cal environmen t, every
network application is a unique instal lation. 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 p erfor ma nce.

When supporting d ual mode 2. 4-GH z a nd 5-G Hz opera ti on, yo u ma y have to pe rfo rm a sit e sur vey for
each of the operating frequenc ies.

Consider the following operating and environmental conditions when performing a site su rvey:

• 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 op eration—When suppo rting bo th sing l e- and dua l-b and a cce ss poi nts, you

should perform a site survey for each of th e operat ing freq uencie s.

• Data rates—Sensitivity and range are inversely proportional to data bit rate s. The maxi mum radi o

range is achiev ed at the lo west workable dat a rate. A decrease in rece iver th reshold sensiti vity occurs
as the radio data increases.

• Antenna type and p lacement—Proper antenna configuration is a critical factor in maximizing radio

range. As a general rule, range incre ases in prop ortion to antenn a height.

• Physical environment—C lear 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 physi cal obstr uctio n su ch a s m eta l sh elvi ng or a stee l p ill ar ca n hi nder

performance of wireless devices. Avoid locating the devices in a location where there is a metal
barrier between the sendi ng and rec eiving 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 barri er to radio signa ls.

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 pack ing mat erials t o the shi pping cont ai ner a nd 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 a ny item i s dama ged or m issin g, no tif y y our aut hori zed Cisc o s ale s rep res enta tive.
