IP address options
You can use the A040 with or without
assigning it an IP address (by default, it has no
IP address).
The simplest method to access all the A040
management interfaces is to assign a unique IP
address to the unit. However, in some cases you
may not want to do this:
• You might have a limited number of
• You might want to move the unit around
• You might not be using a TCP/IP network.
With no IP address, you can still configure the
A040, but you will not have access to all the
management interfaces.

Management (configuration) interfaces
If you want to configure security or specific
network names, or access the A040’s range of
special features, you need to use the built-in
management functions:
• Web Browser Manager – Allows you to
point your standard web browser to the
A040 to access a built-in management
utility
• Command Line Monitor (CLM) – Provides
an ASCII text-based management utility
which you can access using Telnet
• TFTP Transfer – Allows you to perform bulk
uploads and downloads of configuration
settings
• SNMP – Allows you to monitor the unit via
an SNMP manager (not supplied).

A040 Advanced User Guide
Accessing management interfaces
Note: The only way to
configure the adapter
in its factory state is
via a local host
computer, using setup mode or the Nokia
IT Proxy Manager.
There are four methods by which you can
access the management functions:
• Set-up mode
• Nokia IT Proxy Manager
• IP address intercept
• Direct IP address.
For the first two methods above, the adapter
must be connected to a
local host
computer
(a PC directly connected to the adapter)
which has an IP address:
local host
Overview
These methods are described in more detail
below.
9
Generally, it would not
make sense to have an
A040 physically
connected to a LAN, as
its sole purpose is to
connect a standalone
device to a LAN
wirelessly!
Set-up mode
This is a special mode which allows the adapter
to respond (temporarily) to
any
IP address (that
is valid on the local host's subnet).
If the unit were connected to a normal TCP/IP
LAN, responding to any IP address would be a
disaster. However, in set-up mode, the adapter
is only attached to a single host computer.
Assuming that the host computer has a valid IP
address, you can start a Web browser, TFTP or
Telnet application and set up a connection to
any IP address which is valid for your local
subnet (the
intermediate
address). The adapter
will respond immediately to the application,
allowing you to reconfigure it.
Nokia IT Proxy Manager
The Nokia IT Proxy Manager is a software
program supplied by Nokia for Windows 95/98,
Windows 2000 and Windows NT4. The
program uses a special Nokia protocol to
communicate with the adapter in place of TCP/
IP. However, it presents an IP interface
internally to the local host, fooling the Web
browser and Telnet programs into thinking that
they are talking to a TCP/IP device.
The advantage is that this method can be used
without assigning an IP address to the A040
adapter.

A040 Advanced User Guide
IP address intercept
This method can be used once the adapter is
successfully connecting to a network via an
Access Point. It can only be used from the
Access Point side (
computer) and only works if the host device has
an IP address assigned.
The idea behind IP address intercept is that the
adapter finds out the IP address of the host
computer to which it is attached and then
intercepts and uses this IP address for some of
its own management functions. The host
computer never sees the intercepted IP frames.
In its default state, the adapter has the intercept
function turned on. However, you can
selectively enable IP address interception for
any combination of Web, Telnet, TFTP or
SNMP applications. Normally the host
computer does not have Web server, Telnet
server or TFTP server functions so no
functionality is lost by this method. The
operation of client applications on the host are
not affected – the host computer can use its
Web browser or Telnet program to access other
servers in the normal way.
not
from a local host
Overview
Direct IP address
This method can be used once the adapter is
successfully connecting to a network via an
Access Point. It can be used from the Access
Point side or from a local host computer, but
only works if the adapter has a fixed IP address
(it does
not
have one by default).

2. Preparing to configure an adapter
For many applications, the A040 will work
straight out of the box, with no configuration
necessary. You’ll only need to follow the
instructions in this chapter if you need to
change any of the A040 default configuration
settings.
Note that you can only perform the
configuration if you are able to connect the
A040 to a PC supporting TCP/IP. In a non-TCP/
IP environment, you’ll need to set up TCP/IP
temporarily on a workstation.

Installing the A040 utilities
Note: The utilities only
need to be installed on
the machine you want
to use for configuring
attached adapters.
(probably an
administrator's
machine, used for
initial setup).
Before you start to configure the A040, you’ll
need to install some system utilities and default
configuration files onto a desktop or laptop PC
(the local host, which will be directly connected
to the adapter):
• Nokia IT Proxy Manager – Utility for
configuring the adapter from a local host
• Nokia TFTP client – One way to upload new
configuration settings; the only way to
upgrade the system firmware
These are provided on the Utilities CD-ROM.
To install the Nokia IT Proxy Manager, along
with other A040 utilities:
1
Insert the
Nokia A040 Utilities CD-ROM
into the host computer’s CD drive.
The Nokia Utilities application should run
automatically – you’ll see the following
screen after a few seconds:

Using the Nokia IT Proxy Manager
What you’ll need
To configure the adapter using the Nokia IT
Proxy Manager, you’ll need a desktop or laptop
computer (the local host) with the following:
• Windows 95/98, Windows 2000 or
