Safety
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 speci-
fications 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. Refer to Specific Conditions of Use.
The power supply wiring must be sufficiently fused, and if necessary it must be possible
to disconnect manually from the power supply. Ensure compliance to national installation
regulations.
This unit uses convection cooling. To avoid obstructing the airflow around the unit, follow
the spacing recommendations (see Cooling section).
"Note that this unit can be connected to two different power sources."
Before mounting, using or removing this unit:
Prevent access to hazardous voltage by disconnecting the unit from power supply.
Warning
Do not open connected unit. Hazardous voltage may occur within this unit when con-
nected 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.
Care recommendations
Follow the care recommendations below to maintain full operation of unit and to fulfil

Description
L106-F2G EX / L206-F2G EX is an Industrial switch made for harsh enviroments. The
switch can be used in either 100 Mbit or Gigabit networks due to our multi-rate SFP
solution.
L106-F2G EX / L206-F2G EX 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 our
products are 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 trans-
ceivers.
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.

SFP Transceivers
Supported transceivers
Firmware prior to 4.4.0 accepts Westermo branded transceivers only. From 4.5.0 other
transceivers are accepted with a notice and the unit will no longer be UL approved.
Temp.specifications are also depending on the used transeivers.
Note: To comply with UL60950-1 only UL recognized SFP transceivers should be used.
Deviations
With copper transceiver 1100-0148 the specified operating temperature on Lynx
is 0 to +50ºC (32 to +122°F).
FRNT reconfiguration times can not be guaranteed with copper transceivers.

Cable 1211-2027
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.

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.
The Digital in is an opto-isolated
