1 Introduction
The use of router solutions is constantly increasing in the construction of
corporate-wide infrastructures. Bandwidth requirements—especially for
Internet access or the interconnection of branch-office networks—is growing
steadily. Today, 2-Mbit fixed connections are taken for granted in small to
mid-sized businesses. Local-area networks (LANs) that have evolved at
various locations as well as individual PCs can be connected inexpensively by
routers. Corporate branches and offices can be linked to the central network
transparently, making a single, central database available to all systems.
See the following sections for a detailed description of the functions of the
ELSA LANCOM Business, the software and how to use it and an introduction
to the technical basics.

3.2.1 Connecting to the local network (LAN)
Connect your ELSA LANCOM Business to the LAN. Plug the network cable
(supplied) into the 10/100Base-TX terminal of the device and into a free
network connector on your local network (or into a free socket on a hub in
your LAN). The cable for the LAN connector is labeled with a colored bend-
proof protector.
The 'LAN-Link' LED on the front side of the device indicates that a usable
connection to the LAN has been established.
If this LED doesnot come on, reverse the node/hub selector switch. If the LED
still does not light, there may be a problem with the network card or the
wiring.
3.2.2 Connecting to remote networks (WAN)
Depending on the model, up to three 2-Mbit interfaces are available for
connections to remote networks or the Internet:
ELSA LANCOM Business 6001

Connection to the X.21 interface
The X.21 interface permits the connection of a 2-Mbit fixed connection
(D2MU or D2MS) via an external terminal adapter. The X.21 terminal adapter
is connected to a fixed line via its own G.703 interface.
Fixed connections via G.703
ELSA LANCOM
Business 6011 and
6021 only!
You can connect the ELSA LANCOM Business 6011 or 6021 directly to a fixed
line (in Germany under the designations D2MU or D2MS) via the G.703
interface. Insert the appropriate connector cable in the device's G.703 socket.
Connect the stranded wires at the other end of the cable to the D2MU or
D2MS terminals of the network terminator.
In some countries alternative cables are supplied for G.703 connections, with
plugs rather than bare wires, for example.
3.2.3 Connection to the ISDN
The ISDN interface is the direct access for remote computers, for example for
remote configuration. In addition, the ISDN interface can be used to provide
the workstations in the LAN with a variety of office communications
functions such as fax transmission. This can be realized using the included
ELSA LANCAPI software.
Connect the router's ISDN interface to the ISDN network. Insert the supplied
ISDN connector cable in the ISDN/S0bus connection (BRI) of the device and
an ISDN/S0point-to-point or point-to-multipoint connection.
3.2.4 Connection to the serial interface (COM)
The serial interface can be used to configure the device without going over
the network, either with ELSA LANconfig or a terminal program.

Installation of hardware and software |
|ELSA LANCOM Business 6000 |

EN
The pin assignment of the serial configuration interface (COM) of the ELSA
LANCOM Business devices is CISCO-compatible. The corresponding
connector cables or adapters therefore can also be used with ELSA LANCOM
Business routers.
The serial interface automatically sets itself to data rates in the 9,600–
230,400 bps range.
3.3 Activating the router
Finally, connect the router to an AC power socket using the included AC
adapter and switch the device on with the on/off switch on the back.
The router will run a number of test routines to ensure its functionality after
it has been switched on. The progress of the test routines can be monitored
on the display on the front of the device. Once the test routines have been
completed successfully, the device name 'LANCOM BUSINESS 6000' will
appear on the display. The device is now ready for use.
3.4 Installation of the accessory software
The included CD contains a setup program with which you can install the
ELSA software. Place the CD in your CD-ROM drive. If the Setup program
doesn't start automatically, you can start in manually. The file SETUP.EXE is
located in the root folder of the CD.
Follow the onscreen instructions and confirm the queries of the setup
program.
The following applications will be installed:
ELSA LANconfig for the administration of the device under Windows
ELSA LANmonitor to monitor the device under Windows
ELSA LANCAPI for office communications functions via the LAN
The CD also contains a beta version of LANconfig for Linux, xLANconfig,
which features all of the functions of LANconfig. xLANconfig is currently
available for Linux running on x86 and Alpha processors. xLANconfig is based
on the X-Windows standard commonly used in UNIX systems. The complete
functionality of xLANconfig can be provided for any number of X-Windows
clients in the network via an X-Windows server. These clients can use
xLANconfig without the need for a localxLANconfig installation. This feature
makes xLANconfig particularly interesting for deployment in large networks.

3.5 Wizards make life easier
The following chapter will show you how to configure your ELSA LANCOM
Business. This configuration procedure used to be a complicated business
which could easily baffle specialists. ELSA developed software wizards to
simplify the procedure, however, making possible to even realize complex
configurations quickly and reliably.
The wizards can be called up in two ways:
햲ELSA LANconfig
Available under all Windows operating systems. It has also recently been
introduced as xLANconfig for Linux on x86 or Alpha processors.
햳ELSA WEBconfig
An application permanently installed in the router. It can be called up
with any web browser (including text-only browsers) from any operating
system.
The precondition: access to the router via the network.
The same wizards are available for both options. Your choice thus depends
on the operating system of the workstation you intend to use for
configuration. The following overview will be based on WEBconfig. The
information provided also applies to LANconfig and xLANconfig, however.
It's our goal to make the configuration as simple as possible for you. We thus
would like to refer you to the wizards at an early stage in the procedure. The
following chapter contains a complete list of all of the possible configuration
methods. The wizards under LANconfig and WEBconfig are one option.
However, they are the simplest and most reliable option—which is why we
are pointing them out at this early stage.
It's thus worth taking the time for a brief look at the wizards that are available
for the configuration of the ELSA LANCOM Business 6000:

Installation of hardware and software |

In addition to handling the basic and security settings, the wizards can be
used to configure Internet access, set up dial-up access points for remote
access, or establish a direct connection between two local networks.
Needless to say, the full range of expert configuration options is also
available in addition to the wizards. It's only rarely necessary to use these
options, however.
Thewizardshavebeen designedso asto permit the router to be set up easily,
quickly and reliably for typical applications using the wizards alone. The use
of the wizards is self-explanatory. You can find a detailed description of all
of the required information directly in the input window. It's thus not
necessary to refer to the manual. We therefore will not be covering the
individual steps when using the wizards in detail in this manual.
Experience has shown that hardly any problems related to faulty
configurations occur when using the wizards. So, take it easy and simplify
your life with the wizards!
