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.

Die Geräte müssen in einem Bereich welcher einem maximalen Verschmutzungsgrad der
Stufe 2 gemäß IEC/EN 60664-1 entspricht und in einem Gehäuse, das einen Schutzgrad
von mindestens IP54 bietet und die relevanten Anforderungen von N 60079-0 und EN

Alle äußeren Anschlüsse des Gerätes und auch die SFP-Module dürfen nur dann
verbunden oder getrennt werden, wenn entweder der Bereich, in dem das Gerät
installiert ist, nachweislich ungefährlich ist, oder die verbundenen Stromkreise
spannungsfrei sind.
Die Netzwerkkabel müssen nach der Installation mithilfe von Kabelbindern oder
ähnlichem Material ordnungsgemäß befestigt werden, um ein versehentliches Abziehen
der Stecker zu verhindern.

Description
Lynx is an Industrial switch made for harsh enviroments. The switch can be used in ether
100 Mbit or Gigabit networks due to our multi-rate SFP solution. Lynx can also be used
together with our previous Lynx-series of switches. 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 Lynx
is used in safety critical applications such as tunnels, traffic signal control and railway
systems.
Installations in harsh environments and places with heavy electrical interference require
the use of a reliable media. Lynx provides a number of solutions using fibre optic
transceivers. Multi- or singlemode transceivers can be used to build point-to-point or
redundant ring networks with ranges up to 120 km between each switch. Our BIDI
transceiver, which transmits and receives data on a single fibre can be used in applications
where the number of fibre cores are limited.
Real-time properties are implemented in the switch in order to achieve determinism
for real time critical applications. Lynx supports QoS (Quality of Service) with four
priority queues and strict priority scheduling as well as HoL (Head of Line Blocking
Prevention). All to assure that the data network is deterministic.

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.

Lynx supports redundant power connection. The positive inputs are +DC1 and +DC2, the negative input for
both supplies are –COM. Connect the primary voltage (e.g. +24 VDC) to the +DC1 pin and return to one of the
–COM pins on the power input.

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

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.

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.

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.
• 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.
Note! Version of IP Config tool must be 10.3.0 or higher.

Factory default on L110 EX / L210 EX
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 10, and the other between
Ethernet ports 6 and 7.
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.
