Introduction to Wireless Networking
An Access Point (AP) is a device used to extend the existing Ethernet network (structured cabling) to mobile clients
(i.e., laptops, PDAs) enabling mobility, productivity, collaboration and flexibility. Mobile clients can connect to a single
Access Point, or move between multiple Access Points located within the same vicinity, maintaining network
connectivity.
To determine the best location for an Access Point, SYSTIMAX recommends following the SYSTIMAX Certified
Installation Guidelines. For information, contact your local reseller or visit our website at www.systimax.com.
Network initialization and configuration should be performed by the network administrator based on network
requirements.

A wireless network provides:
• Seamless client roaming (not available with 802.1x security)
• Easy installation and operation
• Over-the-air encryption of data
• High speed network links
Guidelines for Roaming
• An AP can only communicate with client devices that support its wireless standard.
• All Access Points must have the same Network Name to support client roaming.
• All workstations with an 802.11 client adapter installed must use either a Network Name of “any” or the same
Network Name as the Access Points that they will roam between. If an AP has Closed System enabled, a client
must have the same Network Name as the Access Point to communicate (see Interfaces Tab).
• All Access Points and clients must have matching security settings to communicate.
• The Access Points’ cells should overlap to ensure that there are no gaps in coverage and to ensure that the
roaming client will always have a connection available.
• The AP541, when set to operate in 802.11b/g mode, operates in the 2.4 GHz band and offers greater range, but
less bandwidth (11 Mbits/s) than when set to operate in 802.11a mode which operates in the 5 GHz band, and has
a lower range but a higher bandwidth (54 Mbits/s).
• All Access Points in the same vicinity should use a unique, independent Channel. By default, the AP automatically
scans for available Channels during boot-up but you can also set the Channel manually (see Interfaces Tab for
details).
• Access Points that use the same Channel should be installed as far away from each other as possible to reduce
potential interference.

IEEE 802.11 Specifications
In 1997, the Institute of Electrical and Electronics Engineers (IEEE) adopted the 802.11 standard for wireless devices
operating in the 2.4 GHz frequency band. This standard includes provisions for three radio technologies: direct
sequence spread spectrum, frequency hopping spread spectrum, and infrared. Devices that comply with the 802.11
standard operate at a data rate of either 1 or 2 Megabits per second (Mbits/s).
In 1999, the IEEE modified the 802.11 standard to support direct sequence devices that can operate at speeds of up to
11 Mbits/s. The IEEE ratified this standard as 802.11b. 802.11b devices are backwards compatible with 2.4 GHz
802.11 direct sequence devices (that operate at 1 or 2 Mbits/s). Available Frequency Channels vary by regulatory
domain and/or country. See 802.11b Channel Frequencies for details.
Also in 1999, the IEEE modified the 802.11 standard to support devices operating in the 5 GHz frequency band. This
standard is referred to as 802.11a. 802.11a devices are not compatible with 2.4 GHz 802.11 or 802.11b devices.
802.11a radios use a radio technology called Orthogonal Frequency Division Multiplexing (OFDM) to achieve data
rates of up to 54 Mbits/s. Available Frequency Channels vary by regulatory domain and/or country. See 802.11a
Channel Frequencies for details.
In 2003, the IEEE introduced the 802.11g standard. 802.11g devices operate in the 2.4 GHz frequency band using
OFDM to achieve data rates of up to 54 Mbits/s. In addition, 802.11g devices are backwards compatible with 802.11b
devices. Available Frequency Channels vary by regulatory domain and/or country. See 802.11g Channel Frequencies
for details.
Management and Monitoring Capabilities
There are several management and monitoring interfaces available to the network administrator to configure and
manage an AP on the network:
•HTTP/HTTPS Interface
•Command Line Interface
•SNMP Management
HTTP/HTTPS Interface
The HTTP Interface (Web browser Interface) provides easy access to configuration settings and network statistics
from any computer on the network. You can access the HTTP Interface over your LAN (switch, hub, etc.), over the
Internet, or with a “crossover” Ethernet cable connected directly to your computer’s Ethernet Port.
HTTPS provides an HTTP connection over a Secure Socket Layer. HTTPS is one of two available secure
management options on the AP; the other secure management option is SNMPv3. Enabling HTTPS allows the user to
access the AP in a secure fashion using Secure Socket Layer (SSL) over port 443. The AP supports SSLv3 with a
128-bit encryption certificate maintained by the AP for secure communications between the AP and the HTTP client.
All communications are encrypted using the server and the client-side certificate.
The AP comes pre-installed with all required SSL files: default certificate, private key and SSL Certificate Passphrase
installed.
Command Line Interface
The Command Line Interface (CLI) is a text-based configuration utility that supports a set of keyboard commands and
parameters to configure and manage an AP.
Users enter Command Statements, composed of CLI Commands and their associated parameters. Statements may
be issued from the keyboard for real time control, or from scripts that automate configuration.
For example, when downloading a file, administrators enter the download CLI Command along with IP Address, file
name, and file type parameters.
You access the CLI over a HyperTerminal serial connection or via Telnet. During initial configuration, you can use the
CLI over a serial port connection to configure an Access Point’s IP address. When accessing the CLI via Telnet, you
can communicate with the Access Point from over your LAN (switch, hub, etc.), from over the Internet, or with a
“crossover” Ethernet cable connected directly to your computer’s Ethernet Port.
See Using the Command Line Interface (CLI) for more information on the CLI and for a list of CLI commands and
parameters.

SNMP Management
In addition to the HTTP and the CLI interfaces, you can also manage and configure an AP using the Simple Network
Management Protocol (SNMP). Note that this requires an SNMP manager program, like HP Openview or Castlerock’s
SNMPc.
The AP supports several Management Information Base (MIB) files that describe the parameters that can be viewed
and/or configured over SNMP:
– MIB-II (RFC 1213)
– Bridge MIB (RFC 1493)
– Ethernet-like MIB (RFC 1643)
– 802.11 MIB
– AirSPEED Enterprise MIB
SYSTIMAX provides these MIB files on the CD included with each Access Point. You need to compile one or more of
the above MIBs into your SNMP program’s database before you can manage an Access Point using SNMP. Refer to
the documentation that came with your SNMP manager for instructions on how to compile MIBs.
The Enterprise MIB defines the read and read-write objects that can be viewed or configured using SNMP. These
objects correspond to most of the settings and statistics that are available with the other management interfaces. Refer
to the Enterprise MIB for more information; the MIB can be opened with any text editor, such as Microsoft Word,
Notepad, or WordPad.
SNMPv3 Secure Management
SNMPv3 is one of two available secure management options on the AP; the other secure management option is
HTTPS (HTTP connection over Secure Socket Layer). SNMPv3 is based on the existing SNMP framework, but
addresses security requirements for device and network management.
The security threats addressed by Secure Management are:
•Modification of information: An entity could alter an in-transit message generated by an authorized entity in such a
way as to effect unauthorized management operations, including the setting of object values. The essence of this
threat is that an unauthorized entity could change any management parameter, including those related to
configuration, operations, and accounting
•Masquerade: Management operations that are not authorized for some entity may be attempted by that entity by
assuming the identity of an authorized entity.
•Message stream modification: SNMP is designed to operate over a connectionless transport protocol. There is a
threat that SNMP messages could be reordered, delayed, or replayed (duplicated) to effect unauthorized
management operations. For example, a message to reboot a device could be copied and replayed later.
•Disclosure: An entity could observe exchanges between a manager and an agent and thereby could learn of
notifiable events and the values of managed objects. For example, the observation of a set command that
changes passwords would enable an attacker to learn the new passwords.
To address the security threats listed above, SNMPv3 provides the following when secure management is enabled:
• Authentication: Provides data integrity and data origin authentication.
• Privacy (a.k.a Encryption): Protects against disclosure of message payload.
• Access Control: Controls and authorizes access to managed objects
The default SNMPv3 username is administrator, with SHA authentication, and DES privacy protocol.
NOTE
The remainder of this guide describes how to configure an AP using the HTTP Web interface or the CLI
interface. For information on how to manage devices using SNMP, refer to the documentation that came with
your SNMP program. Also, refer to the MIB files for information on the parameters available via SNMP.

SYSTIMAX AirSPEED AP541 Hardware Description
The SYSTIMAX AirSPEED AP541 is a tri-mode AP that can support 802.11b, 802.11g, and 802.11a clients. The
AirSPEED AP541 contains a single embedded 802.11a/b/g radio. The unit is software programmable to operate in one
of four modes: 802.11b mode, 802.11g mode, 802.11b/g mode, or 802.11a mode.
SYSTIMAX recommends powering the AirSPEED AP541 with Power over Ethernet (802.3af); alternatively, an external
DC power source using the power cord may be used to power the device.
The AirSPEED AP541 includes a power jack, a 10/100 base-T Ethernet port, and an RS-232 serial data
communication port (Figure 2-1). The AirSPEED AP541 cable cover allows access to the power and cables and to the
reset and reload buttons. The area below the cable cover also serves as a cable routing area.

Dual Band Signal Enhancing Antenna Description
The AirSPEED AP541 can use internal or external antennas. The AirSPEED AP541 has two diversity antennas
embedded for the radio. The internal antennas are arranged to provide both spatial and polarization diversity. The
AirSPEED AP541 also has two external antenna connectors for use with the Dual Band Signal Enhancing Antenna
(SEA).
The Dual Band SEA is a dual band indoor antenna that works with both 2.4 GHz (802.11b/g) and 5 GHz (802.11a)
radios. The Dual Band SEA allows for better antenna placement to enhance the signal for installations in the ceiling or
in RF unfriendly environments.
Antenna Diversity Options
With one Dual Band SEA connected to one of the two external antenna connectors on the radio, the AP supports
antenna diversity (one embedded antenna and one external SEA) and one of the two embedded antennas is disabled.
With two Dual Band SEAs connected to the two external antenna connectors the AP supports antenna diversity (two
external SEAs) and both embedded antennas are disabled.
Prerequisites (for AP Configuration Only)
Before installing an AirSPEED AP541, you need to gather certain network information. The following section identifies
the information you need.
Network Name (SSID of the embedded radio) You must assign the Access Point a Network Name before wireless users can
communicate with it. The clients also need the same Network Name. This is not the same
as the System Name, which applies only to the Access Point. The network administrator
typically provides the Network Name.
AP’s IP Address If you do not have a DHCP server on your network, then you need to assign the
Access Point an IP address that is valid on your network.
HTTP Password Each Access Point requires a read/write password to access the web interface. The default
password is “public”.
CLI Password Each Access Point requires a read/write password to access the CLI interface. The default
password is “public”.
SNMP Read Password Each Access Point requires a password to allow get requests from an SNMP manager.
The default password is “public”.
SNMP Read-Write Password Each Access Point requires a password to allow get and set requests from an SNMP
manager. The default password is “public”.
SNMPv3 Authentication Password If Secure Management is enabled, each Access Point requires a password for sending
authenticated SNMPv3 messages . The default password is “public”.
SNMPv3 Privacy Password If Secure Management is enabled, each Access Point requires a password when sending
encrypted SNMPv3 data. The default password is “public”.
Security Settings You need to determine what security features you will enable on the Access Point.
Authentication Method A primary authentication server may be configured; a backup authentication server is
optional. The network administrator typically provides this information.
Authentication Server Shared Secret This is a password shared between the Access Point and the RADIUS authentication
server (so both passwords must be the same), and is typically provided by the network
administrator.
Authentication Server Authentication Port This is a port number (default is 1812) and is typically provided by the network
administrator.
Client IP Address Pool Allocation Scheme The Access Point can automatically provide IP addresses to clients as they sign on. The
network administrator typically provides the IP Pool range.
DNS Server IP Address The network administrator typically provides this IP Address.
Gateway IP Address and Subnet Mask The gateway IP address and subnet mask of the network environment where the
Access Point is deployed.

Initialization
SYSTIMAX provides two tools to simplify the initialization and configuration of an AP:
•ScanTool
•Setup Wizard
ScanTool is included on the Installation CD; the Setup Wizard launches automatically the first time you access the
HTTP interface.
NOTE
These initialization instructions describe how to configure an AP over an Ethernet connection using ScanTool
and the HTTP interface. If you want to configure the unit over the serial port, see Setting IP Address using
Serial Port for information on how to access the CLI over a serial connection and Using the Command Line
Interface (CLI) for a list of supported commands.
ScanTool
ScanTool is a software utility that is included on the installation CD-ROM. ScanTool allows you to find the IP address
of an Access Point by referencing the MAC address in a Scan List, or to assign an IP address if one has not been
assigned.
The tool automatically detects the Access Points installed on your network, regardless of IP address, and lets you
configure each unit’s IP settings. In addition, you can use ScanTool to download new software to an AP that does not
have a valid software image installed (see Client Connection Problems).
To access the HTTP interface and configure the AP, the AP must be assigned an IP address that is valid on its
Ethernet network. By default, the AP is configured to obtain an IP address automatically from a network Dynamic Host
Configuration Protocol (DHCP) server during boot-up. If your network contains a DHCP server, you can run ScanTool
to find out what IP address the AP has been assigned. If your network does not contain a DHCP server, the
Access Point’s IP address defaults to 169.254.128.132. In this case, you can use ScanTool to assign the AP a static IP
address that is valid on your network.
ScanTool Instructions
Follow these steps to install ScanTool, initialize the Access Point, and perform initial configuration:
1. Locate the unit’s Ethernet MAC address and write it down for future reference. The MAC address is printed on the
product label. Each unit has a unique MAC address, which is assigned at the factory.
2. Confirm that the AP is connected to the same LAN subnet as the computer that you will use to configure the AP.
3. Power up, reboot, or reset the AP.
– Result: The unit requests an IP Address from the network DHCP server.
4. Insert the Installation CD into the CD-ROM drive of the computer that you will use to configure the AP.
– Result: The installation program will launch automatically.
5. Follow the on-screen instructions to install the Access Point software and documentation.
NOTE
The installation program supports the following operating systems:
• Windows 98SE
• Windows 2000
• Windows NT
• Windows ME
• Windows XP
6. After the software has been installed, double-click the ScanTool icon on the Windows desktop to launch the
program (if the program is not already running).
– Result: ScanTool scans the subnet and displays all detected Access Points. The ScanTool’s Scan List screen
appears, as shown in the following example.

NOTE
If your computer has more than one network adapter installed, you will be prompted to select the adapter that
you wantScanTool to use before the Scan List appears. If prompted, select an adapter and click OK. You can
change your adapter setting at any time by clicking the Select Adapter button on the Scan List screen. Note
that the ScanTool Network Adapter Selection screen will not appear if your computer only has one network
adapter installed.

7. Locate the MAC address of the AP you want to initialize within the Scan List.
NOTE
If your Access Point does not show up in the Scan List, click the Rescan button to update the display. If the
unit still does not appear in the list, see Troubleshooting the AirSPEED AP541 for suggestions. Note that after
rebooting an Access Point, it may take up to five minutes for the unit to appear in the Scan List.
8. Do one of the following:
• If the AP has been assigned an IP address by a DHCP server on the network, write down the IP address and
click Cancel to close ScanTool. Proceed to Setup Wizard for information on how to access the HTTP interface
using this IP address.
• If the AP has not been assigned an IP address (in other words, the unit is using its default IP address, ), follow
these steps to assign it a static IP address that is valid on your network:
1. Highlight the entry for the AP you want to configure.
2. Click the Change button.
— Result: the Change screen appears.
