Safety Information
The FCC with its action in General Docket 93-62, 1997, has
adopted a safety standard for human exposure to radio frequency
(RF) electromagnetic energy emitted by FCC regulated equip-
ment. Aironet subscribes to the same safety standard for the use
of its products. Proper operation of this radio according to the
instructions in this manual will result in user exposure substantially
below the FCC recommended limits.
n Do not move the AP1000-T/AP2000-T antenna(s) while the
unit is receiving or transmitting.
n Do not hold any component containing a radio such that the
antenna(s) is(are) very close to, or touching, exposed parts of
the body, especially the face or eyes, while transmitting. Hold
such a component 15 centimeters (6 inches) or more from
your face.
n Do not allow children to play with any radio equipment
containing a transmitter.
n Do not operate a portable transmitter near unshielded
electrical blasting caps or in an explosive atmosphere unless
it is a type especially qualified for such use.
n Do not turn on the AP1000-T/AP2000-T or attempt to transmit
data unless the antenna(s) is(are) attached; if the antenna(s)
is(are) not attached, the radio module may be damaged.
The AP1000-T/AP2000-T are compliant with ANSI C95.1.91
(1991).

The purpose of this User’s Guide is to allow you to install
and configure your Access Point, so that an end node or
another Access Point (acting as a Repeater) will be able to
register to it. For detailed installation and configuration
procedures, see the
AP1000-T/AP2000-T Technical
Reference Manual
.
Before You Start
After unpacking the system, make sure the following items
are present and in good condition.
• Wireless Access Point — 2000 or 1000 series
• 120VAC/60Hz or 90-264VAC/47-63Hz to 12-18VDC
Power Pack
• Standard 2dB Dipole Antenna
If any item is damaged or missing, contact your Reseller.
Save all shipping and packing material to repack the unit in
the future, should service be required.
Terminology
Root Unit - An Access Point which is located at the top of a
RF Network Tree. The Root Unit is the starting point in the
network and contains information in its Registration Table
regarding all nodes on the network.
Repeater - A Repeater is an Access Point which is used to
extend the radio range of your RF Network. A single Access
Point has a limited RF range. If your system configuration
includes nodes outside this range, you will need to add a
Repeater in order for them to communicate.

2
Radio Node - A PC, notebook computer, etc. containing a
Wireless LAN ISA, MCA card or PCMCIA Adapter.
End Node - A Radio Node that is at the end of the RF
Network Tree.
Understanding the Radio Network
Advanced Radio Local Area Network (ARLAN) is designed
like an upside-down tree, with a Root Unit at the top and
repeaters and Radio nodes branching down and out from
the Root as shown in the figure below.
Wireless Access Points can serve as a Root Unit or Re-
peater, providing wireless data communications between
the Token Ring based network and other end nodes, or
within the radio network itself.
In the example shown, the
Root Unit does not register but
will accept Registration from
those nodes within Radio
Range (The Repeater).
The Repeater registers to the
Root Unit and will accept
registrations from those end
nodes within radio range.
The Repeater will pass along
the End Nodes’ registrations to
its parent, the Root Unit.
The Root Unit will have
registration information for all
nodes on the radio network in
the tree.

3
Optional long range antennas are shown below; a range of 6
miles can be achieved with the 900MHz Yagi and 4 Miles
with the 2.4GHz Yagi.

4
Installing the Hardware
With the unit powered off, attach the RP-TNC antenna to
the antenna connector.
Do not over-tighten when connecting, finger-tight is
sufficient. Once connected, make sure the antenna is
positioned vertically to achieve an omni-directional pattern.
Attach the console port cable to the EIA-232-E port and the
other end of the cable to the serial port on a terminal or a
PC running a terminal emulation program.

5
If using STP cabling: The Access Point supports STP
(Shielded Twisted Pair) cabling. Once you have connected
the Token Ring Cabling, you will have to go to the
Configuration-Tokenring-Speed to set the ring speed, and
Configuration-Tokenring-Active-On to allow the Access
Point to enter the ring. Connect the other end of the cable to
a Token Ring Multi-Station Access Unit (MAU).
If using UTP cabling: The Access Point supports UTP
(Unshielded Twisted Pair) cabling. Once you have
connected the Token Ring Cabling, you will have to go to
the
Configuration-Tokenring-Speed to set the ring speed,
and
Configuration-Tokenring-Active-On to allow
the Access Point to enter the ring. Connect the other end of
the cable to a Token Ring Multi-Station Access Unit (MAU).

6
Insert the small plug on the end of the AC/DC Power Pack
Cord into the 12-18VDC port, then plug the AC/DC power
pack into an electrical outlet.
Power-on the Aironet Wireless Access Point by pushing the
ON button.
When power is initially applied to the Access Point, all three
Indicators will flash yellow, red and then green, in sequence,
to test the functionality of the Indicators. The Power-On Self
Test follows. If any power-on test fails, the Status Indicator
will go solid red and the unit will stop functioning.

7
Configuring the Access Point
To configure the Access Point so that it will communicate
with end nodes or Repeaters, you must first use the
Console Port to set the following parameters - SID,
Frequency or Datarate, Root Mode. If you choose to set an
IP address, remote access to the unit is possible via Telnet
or HTML browser.
The Console Port can be accessed directly by connecting
the Access Point to an EIA-232-E terminal emulation
program.
Console Port
To start the Console Port, set the EIA-232-E terminal (or PC
running a terminal emulation program) to
9600 Baud, No-
Parity, 8 data bits and 1 stop bit
.
Power-on the Access Point and the terminal and then type
Yes or No when prompted for the ANSI or Teletype
command.
The Console Port consists of a main menu and a series of
sub-menus containing the configuration parameters from
the Menus. You simply type the name of the parameter or
the menu number and then press ENTER
.
Telnet Session
Telnet sessions can be disabled under Configuration
Console Telnet Off
.
Before starting a Telnet session to a remote Access Point,
you must first assign the unit an IP Address.

8
From the Main Menu, type
Configuration Ident Inaddr and
then type the applicable address.
System Identifier (SID)
The SID is a unique identifier that is attached to each packet
sent out over the radio. You must make sure that the
Access Point is set with the
same SID as the other nodes
on the network with which you would like to share RF
communication
.
You can either set your own SID or ask the unit to pick a
random value for you. This is probably the best way to pick
an SID as there is less chance of conflicting with other
networks that may be in radio range. You may use only one
unit to pick the random value.
This same value must be
used on all other devices on this system
.
At the Console Port, type
Configuration Radio SID and then
enter an even HEX number not exceeding 6 digits, or select
random if you want the Access Point to pick the SID.
Bitrate/Frequency (2000 Series/2.4 GHz Models)
The bit rate and frequency must match those of other nodes
on the RF network. The default bit rate is the highest
available, and the default frequency is the center frequency.
You can accept these defaults or change them as follows.
Type Bitrate and then type the applicable bit rate from the
choices shown. Type Frequency and then type the
applicable frequency from the choices shown.

9
Channel (1000 Series/900MHz Models)
The channel must match that of other nodes on the RF
network. The default channel is the center frequency with
the highest data rate. Since each channel is matched to a
bit rate, changing the channel will also change the bit rate.
Type
Channel and then type the applicable channel from the
choices shown. See
Appendix D in the AP1000-T/AP2000-T
Technical Reference Manual
for more details.
Root Mode
If your Access Point is serving as a repeater (no
connections to the backbone) you should set root mode to
“Off” as follows:
Type
Configuration-Radio-Root and then type “Y”
in response to the argument prompt.
Verifying Registration
Once you have configured your Access Point with the
correct parameters and the end nodes are correctly
configured, RF communication may begin. The Radio
Indicator will flash
“green” indicating RF data traffic. The
Status Indicator will be
“solid green” indicating that one or
more nodes have registered to the unit.
