Before installation:
Read this manual completely and gather all information on the unit. Make sure
that you understand it fully. Check that your application does not exceed the safe
operating specifications for this unit.
This unit should only be installed by qualified personnel.
This unit should be built-in to an apparatus cabinet, or similar, where access is
restricted to service personnel only. The power supply wiring must be sufficiently

Description
L105-S1/L205-S1 is an Industrial switch and device server made for harsh environments.
WeOS is the operating system of L105-S1/L205-S1 enabling the unit to operate in two
functional levels. The switch can be used in either 10 or 100 Mbit networks. Lynx DSS
L105-S1/L205-S1 has one serial port that supports RS-232.
Our unique FRNT (Fast Recovery of Network Topology) technology is the fastest
protocol on the market to re-configure a network in the event of any link or hardware
failure. That is why our products are used in safety critical applications such as tunnels,
traffic signal control and railway systems.

To avoid obstructing the airflow
around the unit, use the following
spacing rules. Minimum spacing 25 mm
(1.0 inch) above / below and 10 mm
(0.4 inches) left / right the unit.
Spacing is recommended for the use
of unit in full operating temperature
range and service life.

Getting Started
This product runs Westermo Operating System (WeOS) which provides several
management tools that can be used for configuration of the unit.
• IPConfig tool
This is a custom Westermo tool used for discovery of attached Westermo units.
Note! Version of IP Config tool must be 10.4.0 or higher.
• Web
Configuration of the unit using the web browser.
• CLI
Configuration of the unit via the Command Line Interface.
Username: admin
Password: westermo
If the computer is located in the same subnet as the switch you can easily use a web
browser to configure the unit. Within the web you can configure most of the available
functions.
For advanced network settings and more diagnostic information, please use the CLI.
Detailed documentation is available in the chapter ”The Command Line Management
Tool” in the WeOS management guide.
Factory default IP address: 192.168.2.200
Netmask: 255.255.255.0
Gateway: Disabled
Note! If you are not sure about the subnet – consult your network administrator.
Configuration
Configure the unit via Web browser
The unit can easily be configured via a Web browser.
Open the link http://192.168.2.200 in your web browser, and you will be prompted with
a Login screen, where the default settings for Username and Password are:
Username: admin
Password: westermo
Once you have logged in, you can use the extensive integrated help function describing
all configuration options. Two common task when configuring a new switch is to assign
appropriate IP settings, and to change the password of the admin account.
The password can be up to 64 characters long, and should consist of printable ASCII
characters (ASCII 33-126); 'Space' is not a valid password character.

17
6643-2230
Factory default on Lynx L105-S1 and L205-S1
It is possible to set the unit to factory default settings by using two straight standard
Ethernet RJ-45 cables.
1. Power off the switch and disconnect all Ethernet cables (copper and fibre).
2. Connect one Ethernet cable between Ethernet ports 1 and 4, and the other between
Ethernet ports 2 and 3.
The ports need to be connected directly by an Ethernet cable, i.e., not via a hub or
switch. Use a straight cable – not a cross-over cable – when connecting the ports.
3. Power on the unit.
4. Wait for the unit to start up. Control that the ON LED is flashing red.
The ON LED flashing indicates that the unit is now ready to be reset to factory
default. You now have the choice to go ahead with the factory reset, or to skip factory
reset and boot as normal.
• Go ahead with factory reset:
Acknowledge that you wish to conduct the factory reset by unplugging the
Ethernet cables. The ON LED will stop flashing.
This initiates the factory reset process*, and the unit will restart with factory default
settings. When the switch has booted up, the ON LED will show a green light, and is
now ready to use.
• Skip the factory reset:
To skip the factory reset process, just wait for approximately 30 seconds
(after the ON LED starts flashing RED) without unplugging the Ethernet cables.
The switch will conduct a normal boot with the existing settings.
* Note Do not power off the unit while the factory reset process is in progress.
