reception, which can be determined by turning the equipment off and on,
the user is encouraged to correct the interference by one of the following
measures:
l
Reorient or relocate the receiving antenna.
l
Increase separation between the equipment and receiver.
l
Connect the equipment into an outlet on a circuit different from
which the receiver is connected.
l
Consult the dealer or an experienced radio/TV technician.
User Warning
The Part 15 radio device operates on a non-interference basis with
other devices operating at this frequency. Any changes or
modification to said product not expressly approved by Aironet could
void the user’s authority to operate this device.

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.
