Before installation:
Read this manual completely and gather all information on the product. Make sure that
you understand it fully. Check that your application does not exceed the safe operating
specifications for this product.
WARNING - SAFETY DURING INSTALLATION
The product must be installed by qualified service personnel
and built in to an apparatus cabinet or similar, where access is
restricted to service personnel only.
During installation, ensure a protective earthing conductor is
first connected to the protective earthing terminal (only valid for
metallic housings). Westermo recommends a cross-sectional area
of at least 4 mm2.
If the product does not have a protective earthing terminal, then
the DINrail must be connected to protective earth. Upon removal
of the product, ensure that the protective earthing conductor, or
the connection to earth via the DIN-rail, is disconnected last.
WARNING - PROTECTIVE FUSE
It must be possible to disconnect manually from the power supply.
Ensure compliance to national installation regulations.
Replacing the internal fuse must only be performed by Westermo
qualified personell.
WARNING - HAZARDOUS VOLTAGE
Do not open an energized product. Hazardous voltage may occur
when connected to a power supply.

6643-22901
WARNING - REDUCE THE RISK OF FIRE
To reduce the risk of fire, use only telecommunication line cords
with a cable diameter of AWG 26 or larger. Regarding power
cable dimensions, see Interface Specifications.
CAUTION - CORROSIVE GASES
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
connector pins.
CAUTION - ELECTROSTATIC DISCHARGE (ESD)
Prevent electrostatic discharge damages to internal electronic
parts by discharging your body to a grounding point (e.g. use a
wrist strap).
CAUTION - HOT SURFACE
Be aware of that the surface of this product may become hot.
When it is operated at high temperatures, the external surface
may exceed Touch Temperature Limit according to the product's
relevant electrical safety standard.
WARNING - POWER SUPPLY CONNECTION
There are safety regulations on which power sources that shall
be used in conjunction with the product. Refer to Interface
Specifications.

Product Description
L206-S2-EX is an industrial switch and device server made for harsh environments.
WeOS is the operating system of L206-S2 enabling the product to operate in two
functional levels. The switch can be used in either 10 or 100 Mbit networks.
L206-S2-EX has two serial ports, one that supports RS-232 and the other configurable
for RS-232/422/485 as well as serial protocols for interconnection with legacy equipment.
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 equipement are used in safety critical applications such as tunnels,
traffic signal control and railway systems.

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.
