Introduction: Aironet 4800B Series
Access Point
Overview
The Aironet 4800B Series Access Point connects to your
Ethernet network and acts as a wireless connection point for
network users. Workstations equipped with a wireless LAN
adapter can connect to the network without being tethered to a
network cable.

Before you begin Installation
Before setting up your Access Point, ask your network system
administrator for the following information:
•An IP (Internet Protocol) address for the Access
Point. Each station or device on your network must have
a unique IP address. The IP address should resemble this
example: 10.0.0.1
•The MAC address from the label on the bottom of the
Access Point. The MAC address should resemble this
example: 0040961234BC
Note: You should configure the Access Point before mounting it
on a pole or a ceiling. Some configuration steps, such as
communicating with the AP through a serial cable, may be
difficult if the AP is inaccessible.
Installation Requirements
Before you begin installation, make sure that you have the
following items:
•The Aironet 4800B Series Access Point
•The Access Point power supply
•The Aironet 4800 Series CD
If any of these items are missing from the Aironet 4800B Series
Access Point package, contact your Access Point supplier.
You will also need:
•A computer that is connected to the same network as the
Access Point
•A nine-pin serial cable (if you use a DHCP server)

Installing the Aironet 4800B Series
Access Point
Follow the instructions below to install the Aironet 4800B Series
Access Point. To take advantage of more of the 4800B Series
Access Point’s features, follow the instructions in the User
Guide.
1. Adjust the antennas.*
For maximum range, make sure the antennas on your Access
Point point straight up or straight down, no matter where
your Access Point is mounted.
If you keep your Access Point on a table or a desk, turn the
antennas so they point straight up. If you mount your Access
Point on a wall or a pole, turn the antennas so they are
vertical, even though the Access Point is on its side. If you
mount your Access Point on the ceiling, turn the antennas so
they point straight down.
*The AP4810B has one antenna. The AP4822B and AP4823B
have reverse TNC connectors so you can attach a wide range of
antennas.

2. Connect the Ethernet cable from your wired LAN to your
Access Point.
Make sure the AP is not powered up when you connect your
network cable.
3. Connect the power pack.
Plug the Power Pack into a wall outlet or a power strip, and
plug the connector into the power receptacle on the back of
the AP.

All three indicators on top of the access point will slowly blink
amber, red, and then green in sequence. During normal operation,
the indicators will blink green. If the indicators display a solid
color without blinking, see the Top Panel Indicator Descriptions
in the User Guide.
Note: If you are not using a DHCP server, skip to step 9.
4. If you have a DHCP server, the server automatically assigns
an IP address to the Access Point when you connect it to
your network. To use the Access Point’s browser-based
management system, you need to find out the assigned IP
address.
Use a 9-pin serial cable to connect the COM 1 or 2 port on
your computer to the RS-232 on the back of the access point.
After you find the assigned IP address, you can remove this
cable. You might need the cable again if you need to update
the AP’s configuration in the future.

*These instructions describe HyperTerminal, but you can use any
terminal-emulation program to communicate with the Access
Point.

Note: If you have a DHCP server, skip to step 10. If you have
a DHCP server, your Access Point’s IP address is assigned
automatically, and cannot be overwritten with the “arp”
command described in step 9.
9. Assign an IP address to your Access Point with the “arp”
command. Follow these steps:
•Open a Command Prompt window (usually located on
your Start menu under Programs).
•Type arp –s followed by the IP address from your
system administrator, followed by the MAC address
from the label on the bottom of the Access Point. Your
complete “arp” command might look like the entry
below.
•Press Enter to set the IP address of your Access Point.
Note: Windows 95 may require you to include your
computer’s IP address in the “arp” command
immediately following the AP’s MAC address. Type
arp in the Command Prompt window and press Enter to
check the proper command format for your version of
Windows.

address line and press Enter. Your Access Point’s
Express Setup Management Screen appears.
Your Access Point is up and running. Consult the User Guide for
a description of all the Access Point’s system management
functions.
Note: If you have trouble browsing to your Access Point, you
may need to use a terminal emulator to assign your AP’s IP
Address and Default Gateway. Follow the steps in the next
section to assign these settings through a terminal emulator.

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.
Aironet products meet the uncontrolled environmental limits
found in OET-65 and ANSI C95.1, 1991. Proper operation 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 touch or move antenna(s) while the unit is
transmitting or receiving.
•Do not hold any component containing the radio such that
the antenna is very close or touching any exposed parts of
the body, especially the face or eyes, while transmitting.
•Do not operate a portable transmitter near unshielded
blasting caps or in an explosive environment unless it
is a type especially qualified for such use.
•Do not operate radio or attempt to transmit data unless the
antenna is connected, if not, the radio may be
damaged.
Dipole Antenna
Always orient antenna such that it is at least 15 cm
(6 inches) away from your body.
High Gain Antennas
High gain wall mount or mast mount antennas are designed
to be professionally installed and should be located at a
minimum distance of 30 cm (12 inches) or more from your
body. Please contact your professional installer, VAR, or
antenna manufacturer for proper installation requirements.
Warning for Laptop User
In order to comply with the FCC RF exposure limits, it is
recommended when using a laptop with a Wireless LAN

Adapter Card, that the Card’s integrated antenna should not
be positioned closer than 5 cm (2 inches) from your body or
nearby persons for extended periods of time while it is
transmitting (or operating). If the antenna is positioned less
than 5 cm (2 inches) from the user, it is recommended that
the user limit exposure time.

Glossary
Association
Each root unit or repeater in the radio network contains an
Association Table that controls the routing of packets between
the Access Point (AP) and the wireless devices. The Association
Table maintains entries for all the nodes situated below the
Aironet Access Point in the radio network including repeaters
and client nodes.
End Node
A fixed or mobile wireless device that communicates with an AP
to access the wired LAN.
Radio Network
The radio network is the communications system that combines
Access Points, mobile nodes, and fixed nodes. Access Points
within the radio network can be either root units, which are
physically wired to the LAN backbone, or can act as wireless
repeaters that extend the range of a root AP. Other wireless
devices serve as fixed nodes or mobile client nodes.
Parent/Child Node
Refers to the relationships between nodes in the wireless
infrastructure. The complete set of relationships is sometimes
described as a Network Tree. For example, the Access Point (at
the top of the tree) would be the parent of the end nodes.
Conversely, the end nodes would be the children of the Access
Point.
Repeater
A repeater is an Access Point that extends the radio range of the
infrastructure. A repeater is not physically attached to the wired
LAN, but communicates via radio to another Access Point, which
is either a root unit or another repeater.
Root Unit
The root unit is an Access Point that is located at the top, or
starting point, of a wireless infrastructure. A root unit provides
the physical connection to the wired LAN and contains

Aironet 4800B Series Access Point
Quick-Start Guide
16
configuration information in its association table that covers all
nodes that access the wired infrastructure. All Access Points
directly attached to the wired LAN backbone are root units.
Service Set Identifier (SSID)
A unique set of characters that identifies which network, of
potentially several radio networks in an area, the fixed or mobile
node should join.
