Safety
Warning
Do not open connected unit. Hazardous voltage may occur within this unit when
connected to power supply.
Note that this unit can be connected to two different power sources.
When this unit is operated at an ambient temperature above +55°C (+131°F), the
External Surface of Equipment may exceed Touch Temperature Limit according to
EN/IEC/UL 60950-1.
To reduce the risk of fire, use only No. 26 AWG or larger telecommunication line
cord.
For more information see General safety 100-5001.

Notice:
This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide
reasonable protection against harmful interference in a residential installation. This
equipment generates, uses and can radiate radio frequency energy and, if not installed
and used in accordance with the instructions, may cause harmful interference to radio
communications. However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the equipment off and on, the
user is encouraged to try to correct the interference by one or more of the following
measures:
… Reorient or relocate the receiving antenna
… Increase the separation between the equipment and receiver
… Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected
… Consult the dealer or an experienced radio/TV technician for help.
Corrosive
environment
Notice:
This product has been successfully tested in a corrosion test according to IEC 60068-
2-60, method 3. This means that the product meets the requirements to be placed in an
environment classified as ISA-S71.04 class G3.
Note! If the product is placed in a corrosive environment, it is important that all unused
connector sockets are protected with a suitable plug in order to avoid corrosion attacks
on the gold plated pins in connectors.

Connection to console port
The console port can be used to connect to the CLI
(Command Line Interface).
The following steps needs to be taken
1. Connect the serial diagnostic cable to the console port
(use only Westermo cable 1211-2027).
2. Connect cable to your computer (USB port, if drivers are needed they can be downloaded
from our Web page).
3. Use a terminal emulator and connect with correct speed and format (115200, 8N1)
to the assigned port.
For more information about the CLI, see the WeOS management guide.

Mounting
This unit should be mounted on 35 mm DIN-rail, which is horizontally mounted inside an
apparatus cabinet or similar. It is recommended that the DIN-rail is connected to ground.
Snap on mounting, see figure.
Mounting Lynx with integrated DIN-clip:
Removal
Cooling
This unit uses convection cooling.
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.
10mm 10mm
Removing Lynx with integrated DIN-clip:
Press down the support at the back of the unit using a screwdriver. See figure.

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
6643-2220
Factory default on Lynx DSS
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 3 and 6, and the other between
Ethernet ports 4 and 5.
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 after approximately 1 minute 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.
