1. Introduction
Congratulations on your purchase of the RangeLAN2 754x Extension Point, a member of
the RangeLAN2 family. The Extension Point will allow you to wirelessly extend the coverage
of your existing RangeLAN2 network. It includes features like Smart Attach and
10BaseFree . Smart Attach is a combination of parameters including Preferred Master
Lists, the Error Domain, and the Backbone Search Timer which enable easy configuration of
the Extension Point devices. With Proxim’s 10BaseFree two-radio architecture, one radio
supports data traffic from mobile clients, much like the radio in a standard Access Point. The
second radio creates a data link replacing the wired Ethernet or Token Ring connection.
Since client and backbone traffic each use their own radio, transmissions occur concurrently
with minimum latency and maximum throughput.
Today, Proxim is the leading supplier of spread spectrum radio networking technology for
local area environments. Proxim's unmatched spread spectrum networking expertise,
combined with the company's extensive experience serving the communications needs of the
mobile computing user, have kept Proxim at the forefront of the emerging wireless LAN
market.
Proxim also manufactures ProxLink. ProxLink is a family of RS-232 cable replacement
products. If you would like more information on ProxLink, please contact Proxim's Sales
Department at 800-229-1630.
The RangeLAN2 Family
RangeLAN2 Extension Point is part of a family of high-performance products that provides a

1
❑ RangeLAN2 7510/752x is a wireless access point which allows for easy
expandability of your wireless network increasing range and facilitating mobility
applications. It operates at the Data Link level (layer 2) of the OSI model,
providing protocol-independent access for RangeLAN2 computer users into
existing wired Ethernet LANs.
❑ RangeLAN2 753x is a wireless access point which allows for easy expandability
of your wireless network increasing range and facilitating mobility applications. It
operates at the Data Link level (layer 2) of the OSI model, providing protocolindependent access for RangeLAN2 computer users into existing wired Token Ring
LANs.
❑ There are two choices of the RangeLAN2 Extension Point -- the 7540 and 7541.
The 7540 has 100 mW output power, while the 7541 has 500 mW output power
from each of the two antennas.
Extension Point Radios
There are two radios on an Extension Point: the BSA and the Backbone radio.
❑ The BSA (Basic Service Area) radio is configured as a Master. It creates a
wireless cell for clients or other Extension Points to synchronize with. It is labeled
BSA Antenna on the Extension Point.
❑ The Backbone radio is configured as a Station and synchronizes to another Extension Point or a Master 7510/752x/753x Access Point which is in turn connected to
the network backbone. It is labeled BB Antenna on the Extension Point.
2
System Requirements
To begin using your Extension Point, you need the following minimum system
requirements:
❑ A RangeLAN2 7510/752x/753x Access Point with V1.3 software attached to
the network backbone
❑ A terminal or PC with a terminal emulation software package and a null
modem cable
OR
a computer running a TCP/IP telnet client and a BOOTP server to assign the IP
address
The Product Package
Each Extension Point comes with:
❑ One Extension Point
❑ One Extension Point User’s Guide
❑ One power adapter
If any of these items are missing or damaged, please contact your reseller or Proxim
Customer Service.
You will need to purchase two antennas in addition to this product package in
order to put the unit in service.

2. Quick Installation
You may follow the quick installation steps if the following conditions are true:
❑
❑
❑
❑
There will only be one Extension Point on this network
You will use all the software default values
You do not need to configure an IP address for the Extension Point and do not
intend to manage it via telnet
You will not be setting Security IDs on your network
If your installation meets the preceding criteria, proceed with the following instructions:
1. Attach each of the antennas onto the antenna connectors on the back
panel of the Extension Point.
Note
Government regulatory agencies mandate that the antenna not be alterable.
Therefore, the Extension Point uses a custom antenna connector. Use only
antennas that Proxim has certified for use with this unit. Contact Proxim
Sales to discuss your antenna configuration.
2. Mount the antennas so that the directional antenna for the BSA radio
points towards the desired coverage area, and the Backbone antenna
points towards the 7510/752x/753x Access Point or Extension Point
supporting the link. You may want to use the Antenna Pointing Tool.
3. Plug the power cable into the back of the Extension Point and into an
AC power outlet. Since there is no On/Off switch on the box, the unit
will turn on as soon as power is applied and search for a Master radio
with which to synchronize.
4. The default settings for the BSA created by the Extension Point are
Domain 0, Channel 2, Subchannel 2, Master Name of EP_MASTER.

3. Physical Installation
Antenna Options
The Extension Point requires two antennas that are purchased separately. Most installations
are well served by one directional (for the Backbone radio) and one omnidirectional (for the
BSA radio) antenna. Each of these antennas ships with installation and mounting instructions.
For information on additional antenna options, please contact your Proxim Sales Representative.
Outdoor Packaging and Mounting Options
If the Extension Point is to be used outdoors, you may want to purchase optional outdoor
packaging. For outdoor packaging options, please contact your Proxim Sales Representative.

4. Wireless Topologies
There are many wireless topologies that can be created using one or several Extension
Points. This chapter explains One-Hop, Multiple Linear, Tree and Building-to-Building
topologies. You can combine topologies to create larger, more complex networks. This
chapter also describes roaming and how it affects the number and configuration of Extension
Points.
Planning and Maintaining the Installation
For optimum performance, pre-installation planning is critical, especially if you have more
than one Extension Point.
There are two radios in the Extension Point. The Backbone (BB) radio, configured as a
Station, synchronizes with a 7510/752x/753x Access Point that is attached to the network
backbone. It can also synchronize with another Extension Point BSA radio. The Basic
Service Area (BSA) radio, configured as a Master, provides an attachment point for wireless
clients, which ultimately allows them to attach to the network backbone.
❑ Determine Domains, Channels, Subchannels, and Master Names for each Master
on the network. Remember to include all 7510/752x/753x Access Points and
BSA radios on all Extension Points.
❑ You can configure Backbone radios on each unit to establish a preferred Master
and fallback Masters. Map out preferred and fallback Masters for each Extension
Point.
❑ If you plan to segment your wireless network using Domains, determine how many
Domains you need. 7510/752x/753x Access Points and Extension Points on
different Domains cannot communicate so you should plan each Domain as a
separate network.
❑ Select Channels for each 7510/752x/753x Access Point and BSA radio of the
Extension Point in the network. Avoid using the same Channel for adjacent or
nearby cells.
11
After initial implementation of the wireless components of the network, additional Extension
Points can be added, although those additions should be planned as carefully as the initial
installation.
Exercise caution when removing an Extension Point from an operational network. Units you
remove may carry active backbone traffic from other cells, and if valid fallback Masters are
not configured and available, that traffic will be disrupted.
One Hop
The single hop architecture is the simplest to plan and install.
In this topology, if the 7510/752x/753x Access Point is set to default Domain, Channel,
Subchannel, and Security ID, the Extension Point may need no configuration. It will turn on,
search for the Master on Domain 0, synchronize with it, and create the BSA for its wireless
clients.
The next figure illustrates the default Domain, Channel and Station Type settings in which the
Extension Point will need no configuration. The 7510/752x/753x Access Point is a Master
configured on Domain 0, Channel 1. The Backbone radio on the Extension Point is configured (by default) as a Station on Domain 0 and synchronizes with this 7510/752x/753x
Access Point. The BSA radio creates a link for the wireless clients as a Master on Domain
0, using a different Channel than that of the 7510/752x/753x Access Point.

One Hop Topology
Multiple Linear
The multiple linear (or multiple hop) architecture involves the use of two or more Extension
Points communicating with one another, with the final unit communicating with the 7510/752x/
753x Access Point. Note that as more Extension Points are installed in a line, performance
to the end wireless clients may decrease. The maximum recommended hop length is 3
Extension Points.
13
The figure below illustrates a two-hop topology. Each Extension Point is further from the
wired 7510/752x/753x Access Point, allowing the final wireless clients to communicate at
greater distances. Note that each Master, while on the same Domain, uses a unique Channel
to create an independent 1.6 Mbps pipe, as described in Chapter 6.

Tree
A tree topology is created when there are two or more Extension Points communicating
directly with the same 7510/752x/753x Access Point. Each of the Extension Points can
support wireless clients. The maximum recommended tree width is 3 Extension
Points.
The next figure shows two Extension Points, each supporting three wireless clients. Again,
note that each Master, while on the same Domain, uses a unique Channel to create an independent 1.6 Mbps pipe.

Building-to-Building
The Extension Point can be used to extend the range of a Building-to-Building link created
using two 7510/752x Access Points. One of the 7510/752x Access Points is configured as a
Master; the other as a Station. The BSA radio of the Extension Point communicates with the
Station 7510/752x Access Point; the Backbone radio communicates with the Master 7510/
752x Access Point.
All radios are configured on the same Domain, and each Master radio has a unique Channel.
The next figure illustrates this configuration.

Roaming
For seamless roaming, all RangeLAN2 devices in the network (7510/752x/753x Access
Points, Extension Points, and PC Cards) must be configured with the same Domain and
Security ID. For best performance, all radios configured as Masters in the network (7510/
752x/753x Access Points and BSA radios in each Extension Point) should use different
Channels when possible. If Channels must be reused, try to avoid using the same Channel in
two adjacent cells.
The user can move freely between the Extension Points and 7510/752x/753x Access Points
in the network. When the roaming PC leaves the transmission range of one Access Point or
Extension Point, the software automatically polls the other Access Points or Extension Points
in the same Domain to continue the network connection.
16
Note:
If the roaming PC must remain connected to the network, cells must
overlap for continuous coverage without gaps.
Roaming stations will only roam among Access Points and Extension Points
with the same Domain and Security ID.
Roaming Scenarios
The following roaming scenarios are supported by the Extension Point:
❑ Roaming among Extension Points
❑ Roaming among Extension Points and 7510/752x/753x Access Points
❑ Backbone radios of Extension Points themselves roaming among Extension Points
and 7510/752x/753x Access Points
How to Configure 7510/752x/753x Access Points When Using
Extension Points
The Repeating Enabled setting on the 7510/752x/753x Access Point defaults to False. If a
tree topology is desired, all 7510/752x/753x Access Points must change that setting to True.
If the default False setting is used, Extension Points will only be able to communicate in a
linear (one hop, multiple linear, building to building) topology.
You must have V1.3 or greater software on the 7510/752x/753x Access Point. Note that
the Access Point software version number is visible in the upper right corner of the menu.
17

5. Configuration
You need to configure the Extension Point if:
❑ There is more than one Extension Point on this network
❑ The 7510/752x/753x Access Point or Extension Point to which this Extension Point
will synchronize is not configured at default Domain or Channel
❑ You need to change the software default values, including IP addresses
❑ You want to set Security IDs on your network
There are four ways to configure the Extension Point:
❑ Locally via a null modem cable and a terminal or terminal emulation package
❑ Remotely across the network using a telnet session
❑ Remotely across the network using an SNMP management package
❑ Remotely across dial-up modems
Locally (Out-of-band)
You may use the DB-9 Local Management Port on the back of the Extension Point to
configure the unit. To locally configure the Extension Point, you need a null modem RS-232
cable with a nine pin female connector on the Extension Point side and a terminal or PC with
an available serial port running a terminal application package.
Note:
If you use a terminal application that has the option to check for the CD signal
before establishing a connection, configure the software to ignore CD.
Alternatively, verify that your null modem cable is a full handshake cable and
pulls CD high.
19
1. Connect the null modem RS-232 cable between the Extension Point
Local Management Port and a free serial port on your terminal or PC.
2. Configure the terminal or terminal emulation package for 9600 bps
N81 operation. If you are using a terminal emulation package, choose
TTY as the terminal type.
3. Apply power to the Extension Point. During the boot process
messages will be displayed on the terminal screen. When they are
completed and you see the “Initialization Complete” message, press
<Enter> to enter the software configuration menu. If the unit was
already turned on, you can press <Enter> to display the menu.
Remotely (In-band)
The second configuration option is remote configuration across the wired network.
Note:
The Extension Point is not manufactured with a default IP address. In order
to telnet to the Extension Point, you must first assign it a valid IP address for
your network using null modem cable configuration or a BOOTP server.
1. From a wired or wireless client on your network, open a telnet session
to the Extension Point. A wireless client must have some link to the
Extension Point in order to open a telnet session. Either it is directly
synchronized to the BSA radio on the Extension Point, or it is
synchronized to a device that contains a wireless communications link
through several other Extension Points.
Note:
You cannot open more than one simultaneous telnet session, nor can you
telnet to an Extension Point that is currently being configured locally.
2. You will be prompted for a password if you enabled this option
through the TCP/IP Configuration Menu.
3. You will enter the configuration menu.
20
Main Menu
After using one of the above two methods, you will see the following software menu whose
choices will be described in the next chapters:
M ain M enu
C onfiguration M enu
Statistics M enu
Status M enu
D ow nload M enu
D iagnostics M enu
R eset Extension Point
Note:
Depending on the current settings of the Extension Point, the order of the
options in the menu tree may change slightly.
SNMP Management
You may configure and monitor the Extension Point using an SNMP management package.
The Extension Point supports the following MIBs:
❑ MIB-II (RFC 1213)
❑ IEEE 802.1d Bridge MIB (RFC 1493)
21
❑ Proxim Enterprise MIB
The Proxim Enterprise MIB is supplied in ASN.1 format. It is available on the
Proxim BBS and Web site. The filename is AP7540.MIB. Follow the instructions
in your SNMP management package for incorporating enterprise-specific MIBs.
Modem Support
The Extension Point may be remotely configured via a dial-up modem. To allow for this type
of configuration:
1. Configure the modem from a terminal or terminal emulation program at 9600 bps.
2. Issue the following commands to the modem:
ATS0=1
AT&D0
ATE0
ATQ1
AT&W0
(Auto-answer after 1 ring)
(Ignore DTR)
(No local echo)
(Suppress result codes)
(Store configuration in non-volatile memory)
3. Attach the modem via a straight-through cable to the Extension Point.
4. From a remote modem, dial the phone number of the modem connected to the
Extension Point.
5. After the Extension Point's modem has answered the phone, press <Enter> on the
terminal connected to the remote modem until you see the configuration menu tree .

IP Address indicates the IP address that will be assigned to the Extension Point. It must be
a unique number on the network. This parameter will not change until the Access Point is
reset.
Subnet Mask indicates the mask that will be used to determine what network the Extension
Point is on. This parameter will not change until the Extension Point is reset.
If a packet is destined for an IP host or node belonging to a different IP subnet, the Extension
Point will send IP packets to the Default Gateway (usually a router) for the packets to be
routed to the proper destination. This parameter will not change until the Extension Point is
reset.
24
You can enable or disable the Extension Point's ability to request its IP address from a
BOOTP server at boot time, and you can supply the IP address of that server.
You can enable or disable the ability to open a telnet session to the Extension Point and set a
password to control telnet access.

This option allows you to change the various wireless parameters for the BSA radio.
Radio Port Administrative Status is used for SNMP. It corresponds to the SNMP MIBII Administrative status parameter and can be used to bring the BSA radio interface back up
after it has been disabled by an SNMP manager. It can also be used to put the radio into a
mode in which it no longer transmits or receives packets.
In order to establish communications, all communicating radios must be configured with the
same Domain number. Radios on different Domains cannot communicate with each other.
The Domain is a software filter which does not affect the actual radio frequency or the
frequency hop sequence.
In order for the wireless clients to roam between Extension Points and 7510/752x/753x
Access Points, all radios must be configured to the same Domain.
Each Master can select one of 15 Channels to establish communications with Stations.
Each Channel number sets a unique frequency hopping sequence allowing for multiple subnetworks with higher data rate transmission capability in the same air space. You may think of
the Channel as a pipe. In order to communicate, there must be one (and only one) Master
that provides the timing for that Channel.
There are 15 independent Channels. This means that there are 15 different sequences of
frequency hops. Each Channel is at a different frequency at a different time. For networks
with multiple Masters (such as in a roaming environment), set each Master to a different
channel. All Stations will determine their channel by the Master to which they are synchronized.
The Subchannel is a software code that is appended to each radio packet. It does not
affect the frequency hopping sequence like a Channel does. Use a Subchannel if you need
more than 15 Masters in the same coverage area and, therefore, all the Channels are used.
For example, you can use Channel 1, Subchannel 1 for Network A and Channel 1,
Subchannel 2 for Network B. The two networks will not communicate with one another.
They are, however, still sharing the 1.6 Mbps pipe since they are both using Channel 1.
27
The Error Domain is the Domain used by the BSA radio if the Backbone radio loses
synchronization with all the Masters in its list. It will switch to this Domain after the amount of
time specified in the Error Domain Timer parameter has passed without finding an acceptable Master.
The Master Name parameter specifies an alphanumeric name to simplify the identification of
each Master in your network. This parameter is case sensitive.
Repeating Enabled controls the ability for the Extension Point to repeat signals coming
from one Station and destined for another Station. These two Stations must be out of range
of one another but both in range of and synchronized to the Extension Point for repeating to
occur.
The Delay Radio Reconfigure parameter allows you to delay radio parameter changes
from taking effect. You might want to enable this feature so that you do not lose communication when a parameter is changed .
The MAC Optimize parameter can help improve throughput for small networks. The
default setting of Auto causes the Extension Point to determine the number of units synchronized to it and adjust this parameter accordingly. Alternately, you may force the parameter to
one of the other settings. If you have 0 or 1 wireless nodes communicating with an Extension
Point, use the Very Light setting. If you have between 2 and 7 wireless nodes communicating
with an Extension Point at the same time, use Light. (You can have more than 7 nodes
synchronized to an Extension Point but between 2 and 7 communicating at the same time for
the Light parameter setting.) In networks with more than 7 concurrent wireless users, use
Normal.
The No Traffic Trap Period specifies the number of seconds after which a No Traffic trap
is sent via SNMP.
The Radio Traffic Trap Threshold specifies a percentage of radio traffic after which a
Radio High Usage trap is sent via SNMP.
The Radio Broadcast Trap Threshold specifies a percentage of radio broadcast traffic
after which a Radio High Usage trap is sent via SNMP.
28
To further improve the security of a wireless subnetwork, each unit requires the same Security ID to establish communication. The Security ID is used on all RangeLAN2 products
and all Station Types. This ID is encrypted and stored in the Extension Point itself, not in
software. It cannot be accessed but you may change it. If you do change it, however, you
will need to change the Security ID on all other radios with which this one was communicating. The Security ID parameter can be up to 20 characters and is an empty string by default.
It is case sensitive.
Reset Radio allows you to reset the BSA radio contained in the Extension Point without
resetting the entire unit. This will cause any changes to the radio parameters which have not
yet taken effect (because the Delay Radio Reconfigure parameter is set) to take effect.

This menu allows you to change the various wireless parameters for the Backbone radio.
The parameters with the same name as those under BSA Radio Configuration will not be
described again except to note changes.
29
The First Master To Sync To parameter names the Master with which this Extension Point
will synchronize. If this field is filled in, there will be another choice, Second Master To
Sync To. If the first Master is unavailable to the Extension Point, it will look to the second
Master. Similarly, if the second choice is filled in, a Third Master To Sync To field will be
visible. If none of these fields is filled in, the radio will continually look for the best Master.
These parameters are case sensitive.
When High Priority Protocol Enabled is set to true, the Backbone radio is given an advantage over wireless clients for use of the Channel, and thus is able to transmit more packets
than a wireless client. If you have three or more Extension Points in the same BSA, set this
parameter to False.
You may enable or disable the ability for the Backbone radio to roam when it loses synchronization with its Master via the Roaming Enabled parameter. If the list of First Master To
Sync To, Second Master To Sync To, and Third Master To Sync To is configured, this
parameter is ignored. If the list is not configured and the Roaming Enabled field is set, the
radio will search for any available Master . When the list is not configured and roaming is
disabled, the radio will never roam.
SNMP Management
SNMP Management is described in Chapter 9.
Reset Extension Point to Factory Defaults
Use this option to reset all the parameters to default values. This option is only visible when
configuring the Extension Point via a terminal, not via telnet or SNMP.

BSA Radio Status Menu
The current Extension Point BSA radio parameters are displayed in this menu option. These
will match those in the Configuration Menu with the exception of MAC Optimize. If MAC
Optimize is configured as Auto, it will still appear in the Status Menu as Very Light, Light or
Normal, depending on the current number of synchronized radios.
The Radio Traffic Level and Radio Broadcast Level parameters show the current values
of these parameters which may cause an SNMP trap.
The Radio ROM version of the radio contained inside the BSA port of the Extension Point
is available for viewing.
If there is a parameter that will not take effect until the Extension Point or BSA radio is reset,
the Reset Required for Reconfiguration parameter will be set to “true.” For example,
after changing the radio Channel through the Configuration Menu, this parameter would be
set to “true.”
The Number of Radio Stations Connected parameter displays a count of the current
RangeLAN2 devices that are synchronized to this Extension Point and have communicated
within a specified time period. This time period is defined by the Aging Period parameter,
which can be configured under the Bridge Configuration Menu.
Backbone Radio Status Menu
The current Extension Point Backbone radio parameters are displayed in this menu option.
The Channel and Subchannel refer to those of the Master to which it is synchronized.
These parameters are not visible when the Backbone radio is not synchronized to a Master.
Synced-To Master Name is the name of the Master to which the Backbone radio is
synchronized. This parameter is not visible when the Backbone radio is not synchronized to a
Master.
34
The First Sync To parameter lists the name of the Master to which this Extension Point
will first look to synchronize. If programmed, there will also be parameters for Second
Sync To and Third Sync To.
The Roaming Enabled parameter can differ from its configured value if any Sync To parameters are set. The Roaming Enabled parameter is set to “false” if one or more of these are
programmed, even if the Configuration Menu indicates it is “true.”
If there is a parameter that will not take effect until the Extension Point or Backbone radio is
reset, the Reset Required for Reconfiguration parameter will be set to “true.” For
example, after changing the radio Channel through the Configuration Menu, this parameter
would be set to “true.”
Bridge Status Menu
The Bridge Address is the MAC address of the Extension Point.
TCP/IP Status Menu
The current IP Address, Subnet Mask and Default Gateway are displayed.
Forwarding Database Table
The Extension Point is a learning bridge. Over time, from watching the packets on the
network, the Extension Point determines where the nodes on the network are -- on the BSA
or Backbone side of the Extension Point. You can view the table of nodes known to the
Extension Point. This table can hold a maximum of 2048 entries.

The Extension Point supports the following MIBs:
❑ MIB-II (RFC 1213)
❑ IEEE 802.1d Bridge MIB (RFC 1493)
❑ Proxim Enterprise MIB
The Proxim Enterprise MIB is supplied in ASN.1 format. It is available on the
Proxim BBS and Web site. The filename is AP7540.MIB. Follow the instructions
in your SNMP management package for incorporating enterprise-specific MIBs.
Note:
The Extension Point is not manufactured with a default IP address. In order
to SNMP manage the Extension Point, you must first assign it a valid IP
address for your network using null modem cable configuration or a BOOTP
server.
You may choose to configure the Extension Point through the menu trees (in-band or out-ofband) to set SNMP parameters before using an SNMP manager.
Enable/Disable SNMP allows you to enable or disable SNMP management of
the Extension Point.
The Read-Only SNMP Community parameter specifies a community supported
by the Extension Point. Actions permitted by this community are “read-only” (GET
and GET-NEXT). SET attempts using this community will result in rejection of the
attempt with a general error response and the generation of an authentication trap (if
so enabled).
The Read-Only SNMP Manager IP Address specifies the IP address of the
SNMP manager which is permitted to use the Read-Only SNMP Community. An
address of 0.0.0.0 indicates any manager may use this community.
38
The Read/Write SNMP Community parameter specifies the community
supported by the Extension Point. Actions permitted by this community are
“read-write” (GET, GET-NEXT, and SET).
The Read/Write SNMP Manager IP Address specifies the IP address of the
SNMP manager which is permitted to use the Read/Write SNMP Community. An
address of 0.0.0.0 indicates any manager may use the community.
The SNMP Trap Community parameter specifies the community that will be used
by the Extension Point when generating TRAP PDUs (Protocol Data Units) to
remote managers.
The Trap Target Address specifies the IP address of the device to which generated TRAP PDUs will be sent. A value of 0.0.0.0 disables trap generation.
Authentication Traps are sent to the Trap Target Address whenever anyone
attempts to SNMP manage the Extension Point with an invalid community or from
an invalid community. You may enable or disable the sending of these traps.
SNMP Supported Traps
The following traps are supported by the Extension Point and are sent to the SNMP
manager defined by the Trap Target Address when they occur.
MIB II Traps
Cold Start - Sent when the Extension Point powers on or reboots.
Link Up - Sent by each interface at start-up or after coming back up.
Link Down - Sent when the Extension Point software cannot initialize or communicate with either interface.
Authorization - Sent to the network manager when someone tries to manage an
Extension Point with an invalid community.
39
Enterprise Specific Traps
No Traffic - Sent when set to a non-zero value and when the Extension Point
does not receive any traffic from other radios for the configured period of time.
The time may be configured in the BSA Radio Configuration Menu.
Broadcast Threshold - Sent if the radio broadcast traffic exceeds the limit set
by the BSA Radio Configuration parameter, Radio Broadcast Trap Threshold.
Cache Table High Usage - Sent when the cache table usage percentage has
exceeded the limit set by the Bridge Configuration parameter Forwarding DB Usage
Trap Threshold. For example, if this limit were set to 50%, when the Extension
Point knows 1024 (out of the 2048 possible) entries, it will send this trap message.
Radio High Usage - Sent if the radio traffic has crossed the limit set by the BSA
Radio Configuration parameter Radio Traffic Threshold.
Serial Port Down - Sent when the serial port of the Extension Point is not working.
The status of this port is checked only at boot time.

10. Performance Hints
This section provides the user with ideas as to how to increase performance and network
satisfaction on a wireless network.
Microwave Ovens
Microwave ovens operate in the same frequency band as RangeLAN2. Therefore, if you use
a microwave within range of RangeLAN2 (about 10') you may notice network performance
degradation. However, both your microwave and your RangeLAN2 network will continue
to function.
Range
Every environment is unique with different obstacles, barriers, materials, etc. and therefore, it
is difficult to determine the exact range that will be achieved without testing. The site survey
tool and antenna aiming tools were developed to aid in this process. Additionally, Proxim has
developed guidelines to estimate the range that users will see when the product is installed in
their facility, but there are no hard and fast specifications.
Radio signals may reflect off of some obstacles or be absorbed by others depending on their
construction. For example, with two RangeLAN2 radios using our lowest gain antennas, you
may achieve up to 1000' in open space outdoors where the two antennas are line of sight,
meaning they see each other with no obstacles. However, the same two units will only
achieve up to 500' of range when they have to travel through the cubicles usually used in
modern offices. If there are office walls to penetrate, the signal range may decrease even
further to up to 300'.
If you are interested in antenna options, contact your Proxim Sales Representative about
antenna kits.
41
42
11. Site Survey, Antenna Pointing Tool,
and Master Search Tool
The Extension Point has three mechanisms to determine proper placement of radios and
antennas: a site survey tool which displays the quality of the wireless link between the BSA
radio and its wireless clients; an antenna pointing tool to aim the Backbone radio's antenna;
and a Master search tool which displays information on all visible Masters.
A network administrator might use these tools when diagnosing user performance problems.
A network installer use them to aid in determining placement of the Extension Point and
wireless client antennas.
These tools are accessible from the BSA and Backbone Radio Diagnostics Menus. The
site survey tool shows the MAC addresses, Link Quality and RSSI of each wireless node
that is connected to the BSA radio of the Extension Point. The Antenna Pointing Tool
measures throughput between theExtension Point radio and the 7510/752x/753x Access
Point (or other Extension Point) to which it is synchronized as packets per second and
kilobits per second. The Master Search Tool (available on the Backbone Radio Diagnostics Menu only) displays configuration information on all Masters within range of the
Extension Point.
To perform a site survey, first choose the Run Broadcast Site Survey option and let the
Extension Point scan for a period of time that you specify. Then look at the list of MAC
addresses found, Link Quality and RSSI data. The results will show an average value for
each parameter over the time period for which the site survey was run. If you check the data
before the full time has elapsed, you will see values that are an average of the time thus far
elapsed.
43
Figure 9
Broadcast Site Survey
The higher the Link Quality number from a particular node, the better the link. A Link
Quality number of 0 indicates that the node is no longer responding at all. This is the most
important parameter to watch to verify that you will be able to maintain a reliable wireless
connection. Note that the Link Quality number of RangeLAN2 7200 and 7400 adapters may be low if those adapters are in their doze mode when being surveyed. As
these adapters wake up, the Link Quality number may change, so this number may
not always be accurate.
Received signal strength (RSSI) indicates how strong a signal was received from a particular
node.
44
After using the Broadcast Site Survey, you can choose the Run Directed Site Survey to
check the packets per second and bytes per second measurements between the Extension
Point and the node you select.
Figure 10
Directed Site Survey
45
On the BSA radio, the Antenna Pointing Tool prompts for MAC address, packet size and
sample interval. Enter the MAC address of any Station which is synchronized with the BSA
radio. If there is only one Station synchronized to the BSA radio, its MAC address will be
listed by default.
Figure 11
Antenna Pointing Tool on the BSA Radio
46
On the Backbone radio, the Antenna Pointing Tool prompts for packet size and sample
interval, as well as whether or not you want to permit roaming during the test. The MAC
address of the current Master is displayed. If roaming is enabled, you can move the Backbone radio antenna and synchronize with a different Master. The last parameter displayed
indicates if the Backbone radio is synchronized to a Master.
After answering all prompted questions, the tool will run until stopped so that you can experiment with various placements of the antenna until the optimum location is determined.
The Master Search Tool, under Backbone Radio Diagnostics, searches for Master units
within range of the Backbone radio. After running, a directed site survey is immediately
launched. The Master Search Tool prompts for both length of time to run the tool and
length of time to run the site survey.
The Master Search Tool displays the MAC address, Master Name, Channel, and
Subchannel of all Masters it finds. The site survey displays the Kbytes/sec and RSSI values
between the Backbone radio and the Master.

Installation Checklist
In case of installation difficulties, verify the following:
❑ All 7510/752x/753x Access Points must have V1.3 or later software. Note that the
software version is listed in the upper right corner of the menu.
❑ All Masters that are using the same Domain and Security ID should have unique
Channels wherever possible. If there are more than 15 Masters, reuse Channels on
Masters that are not geographically adjacent. Use the Discover APs/EPs command from the Diagnostics menu to view all the Masters.
❑ Verify there is a link to the wired Ethernet backbone using the Display Wireless
Network Tree command from the Diagnostics menu.
❑ Use the Antenna Pointing Tool or the Run Directed Site Survey option from
the Backbone Radio Diagnostics Menu to ensure optimum antenna placement,
especially of directional antennas. Antennas should be no closer than 6' apart.
❑ In a tree topology, repeating must be enabled on the 7510/752x/753x Access Point
that is connected to the network backbone, as well as all Extension Points.
❑ In order to ensure seamless roaming, use the same Domain and Security ID on all
Master 7510/752x/753x Access Points and Extension Point BSA radios.
❑ Verify all Masters listed in the First Master To Sync To, Second Master To
Sync To, and Third Master To Sync To configuration parameters are within
range of the Backbone radio by using the Master Search Tool and are listed
correctly.

Commonly Asked Technical Support Questions
Problem/Symptom/Question
Possible Solution/Answer
Chapter in
User’s Guide
Is theExtension Point fully booted?
The status LED changes from steady yellow to steady green
12
I can’t connect to the network from
wireless client.
1. Verify the wireless connection using the Site Survey Tool of
the Extension Point or of the client.
2. Verify that the Extension Point’s Backbone radio has a path
to the wired network via 7510/752x/753x Access Points and
other Extension Points.
3. Verify that the 7510/752x/753xAccess Point connected to
the network backbone is not filtering out the kind of traffic the
client is trying to pass.
# 1 - 11
#2-4
Why is the Status LED flashing
yellow?
The Backbone port of the Extension Point cannot synchronize
to a Master. Verify it is still in range of the one of the Masters
listed as First, Second or Third Master to Sync To using the
site survey tools. If there are no Masters listed, verify that
Roaming Enabled is set to True.
11
I can’t ping or telnet to my brand
new Extension Point.
There is no default IP address. The first time you use the
Extension Point, set an IP address using a terminal and null
modem cable or a BOOTP server.
5
How can I tell which side of the
Extension Point a client is on?
View the Forwarding Database in the Status Menu. Units on
the BSA port are synchronized to or bridged through the
Extension Point.
8
How can I tell to which
7510/752x/753x Access Point my
Extension Point is synchronized?
Use the Display Wireless Network Tree or the Current SyncTo Master Name in the Backbone Radio Status Menu.
12, 8
I can’t configure the Extension
Point locally via the serial port.
Verify you are using a null modem cable and that the terminal
is set to 9600 N81.
5
I can’t establish a wireless
connection with theExtension
Point.
Verify that the client is set to the same Domain and Security
ID of the BSA port of the Extension Point and that the client
is configured as a Station.
6
The throughput seems slow.
To achieve maximum throughput, verify your antennas are wellplaced, not behind metal, and there are not too many
obstacles. If you move the antenna closer to the client and
throughput increases, you may want to consider adding
additional 7510/752x/753x Access Points or Extension
Points.
10
How long does my Extension
Point Backbone take to start
searching for alternate Masters
when the first one is unavailable?
50 seconds
When the Extension Point is not
connected with the network, how
can I communicate with it?
Either via the serial port using a terminal emulation program,
or a telnet session from a wireless client that is configured on
the Error Domain.
5
How do I know that I have selected
the best position for my directional
antenna.
Either use the Antenna Pointing Tool or perform a Direct Site
Survey to verify optimum connection.
11
How do I disable the Error
Domain?
Set it to the same Domain number as the Configured Domain.
The status LED on theExtension
Point is steady red.

LED Indicators
There are three LEDs on the front of the Extension Point:
❑ The cornermost LED, called the System LED, changes from yellow to green to
indicate the Extension Point is functional. It changes from yellow to red if there is a
hardware problem with the unit. If this LED does turn red, contact Proxim Technical
Support. The LED will blink yellow if the Extension Point has entered the Error Domain because it cannot find a Master on the Backbone with which to synchronize.
❑ The center orange LED, called the BSA LED, flashes when the Extension Point is
forwarding packets to its Basic Service Area (BSA).
❑ The third green LED, called the Backbone LED, flashes when the Extension Point is
transmitting through the Backbone (BB) radio.

The steps for downloading a new image are:
1. Choose a method of download (Xmodem, TFTP, FTP) and place the image file on
that hard drive, floppy diskette, server, etc.
When performing an Xmodem download, use the Xmodem or Xmodem CRC
protocols.
2. Bring up the menu on the Extension Point via a terminal with a null modem cable or
a telnet session.
3. Choose the Download Menu off the Main Menu.
4. Choose the Download type, i.e. Download EP Image Using Xmodem, etc.
5. Answer the on-screen prompts for server IP address, username, etc.
6. When download is successful, the Extension Point will automatically reboot and
load the new image.
The Extension Point also has the ability to update other Extension Points' software. You can
choose to Update Images of All EPs or Update Images of Selected EPs. In these two
cases, the Extension Point will first discover other Extension Points. The difference between
these two options is the ability to exclude certain units from receiving the new image. If you
know the IP address of a specific Extension Point that you would like to update, choose the
Update Image of a Specific EP option and provide the IP address when prompted. If you
do not want an Extension Point to receive an updated image, disable the Accept Downloads
from Other EPs parameter.
To view the status of downloads on other Extension Points, see the EP Download Table.

C. Glossary
Access Point - An internetworking device that seamlessly connects wired and wireless
networks together.
Bandwidth — The size (in Hertz) of the frequency range that a signal transmission occupies.
Typical narrow band signals occupy a 25 KHz bandwidth. The RangeLAN2 signal occupies
a 1 MHz bandwidth.
BB (Backbone) — The Station radio of the Extension Point that synchronizes with a Master
to attach to the network backbone.
BOOTP (Bootstrap Protocol) — A protocol used to assign IP addresses.
BSA (Basic Service Area) — A virtual cell created by the Master radio on the Extension
Point. RangeLAN2 Stations synchronize with the BSA radio.
Channel — In RangeLAN2 networks, the Channel refers to the frequency hopping sequence the card follows.
CSMA/CA — (Carrier Sense Multiple Access/Collision Avoidance) — CSMA is a protocol in which each node senses whether or not a channel is in use before attempting to transmit
information. CA is an optimization by which channel time is reserved to avoid collisions.
Download Image — A software file that is used to upgrade the software code running on
the Extension Point.
Frequency Hopping — A spread spectrum technique by which the band is divided into a
number of frequencies and the transmissions hop fromfrequency to frequency in a prespecified sequence.
Interference — A situation that occurs when an unwanted RF signal occupies the same
frequency band as a desired signal.
66
IP Address (Internet protocol address) — A 32-bit address assigned to TCP/IP hosts.
Spread Spectrum — A radio data transmission modulation technique by which the transmitted signal is spread over a bandwidth wider than the information bandwidth. In the U.S.,
Spread Spectrum bands are designated by the FCC and require no user license.
SNMP ( Simple Network Management Protocol) — A protocol used to manage network nodes.
TCP/IP — Transmission Control Protocol / Internet Protocol. A suite of protocols developed under DARPA sponsorship for internetworking.
