3. Product Description
3.1. Product Description
Lynx DSS is a device server with a managed layer 2 and 3 industrial Ethernet switch,
powered by the Westermo WeOS network operating system. It is the most compact and
has the lowest power requirements in this class of device servers.
Lynx DSS is the most compact, and has the lowest power requirements, in this class of
device servers. It has four pieces of 10/100 Mbit/s ports in addition to two ports which can
be fitted with Gbit or 100 Mbit SFP transceivers and two serial ports. One serial port is
configured for RS-232, the other one can be configured for either RS-232 or RS-422/485.
Lynx DSS is designed for simple use in industrial applications, from the robust DIN rail clip
solution to the configurable fault contact and the industrial level of dual power inputs.
Only industrial grade components are used which gives Lynx DSS an MTBF of 517,000
hours and ensures a long service life. A wide operating temperature range of -40 to +70°C
(-40 to +158°F) can be achieved with no moving parts or cooling holes in the case. Lynx
DSS has been tested both by Westermo and external test institutes to meet many EMC,
isolation, vibration and shock standards, all to the highest levels suitable for heavy industrial
environments and rail trackside applications.
WeOS has been developed by Westermo to offer cross platform and future proof
solutions. For more WeOS functionality, please see the WeOS datasheet.

The Status output is a potential free, opto-isolated, normally closed, solit-state relay. This
can be configured to monitor various alarm events within the unit, see WeOS Management
Guide. An external load in series with an external voltage source is required for proper
functionality. For voltage/current, see Interface Specification section.
The Digital in is an opto-isolated digital input, which can be used to monitor external
events. For voltage/current, see Interface Specification section.

4.4. Getting Started
This product runs the Westermo Operating System (WeOS) which provides several
management tools that can be used for configuration of the unit.
•WeConfig tool
This is a custom Westermo tool used for discovery of attached Westermo product.
•Web
Configuration of the product using the web browser.
•CLI
Configuration of the product 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 product. Within the web you can configure most of the available
functions. If you are not sure about the subnet – consult your network administrator.
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:
Lynx L108-F2G-S2 and L208-
F2G-S2 19

IP address: 192.168.2.200
Netmask: 255.255.255.0
Gateway: disabled
4.5. Configuration Via a Web Browser
The product 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 are:
Username: admin
Password: westermo
Once logged in, 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.
NOTE
Note! Version of WeConfig tool must be 10.3.0 or higher.
4.6. Factory Default
It is possible to set the product to factory default settings by using two straight standard
Ethernet RJ-45 cables.
1. Power off the product and disconnect all Ethernet cables (copper and fibre).
2. Connect one Ethernet cable between Ethernet ports 3 and 6, and the other between
Ethernet ports 4 and5. 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 product.
4. Wait for the product to start up. Control that the ON LED is flashing red. The
product is now ready to be either reset to factory default or to boot as normal.
To go ahead with factory reset:
NOTE
Do not power off the product while the factory reset process is in
progress.
