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.
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.

66643-22701
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 - CLASS 1 LASER PRODUCT
Do not look directly into a fibre optical port or any connected
fibre, although the product is designed to meet the Class 1 Laser
regulations and complies with 21 CFR 1040.10 and 1040.11.
CAUTION - HANDLING OF SFP TRANSCEIVERS
SFP transceivers are supplied with plugs to avoid contamination
inside the optical port. They are very sensitive to dust and dirt. If
the fibre is disconnected from the product, the protective plugs
on the transmitter/receiver must be connected. The protective
plugs must be kept on during transportation. The fibre optics
cables must be handled the same way.

6643-22701
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.
Product disposal
This symbol means that the product shall not be treated
as unsorted municipal waste when disposing of it. It needs
to be handed over to an applicable collection point for
recycling electrical and electronic equipment.
By ensuring this product is disposed of correctly, you will
help to reduce hazardous substances and prevent potential
negative consequences to both environment and human
health, which could be caused by inappropriate disposal.
Care recommendations
Follow the care recommendations below to maintain full operation of product and to
fulfill the warranty obligations:
• Do not drop, knock or shake the product. Rough handling above the specification
may cause damage to internal circuit boards.
• Use a dry or slightly water-damp cloth to clean the product. Do not use harsh
chemicals, cleaning solvents or strong detergents.
• Do not paint the product. Paint can clog the product and prevent proper operation.
If the product is used in a manner not according to specification, the protection provided
by the equipment may be impaired.
If the product is not working properly, contact the place of purchase, nearest Westermo
distributor office or Westermo technical support.
CAUTION - CABLE TEMPERATURE RATING FOR
FIELD TERMINAL WIRES
There may be a requirement on the minimum temperature rating
of the cable to be connected to the field wiring terminals, see
Interface Specifications.

All external connections to the equipment and, where applicable, the SFP modules must
not be inserted or removed unless either the area in which the equipment is installed is
known to be non-hazardous, or the circuits connected have been de-energized.
The network cables once installed must be properly fixated by the use of cable ties or
similar to reduce the risk of accidently withdrawing the plugs.

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 multirate 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 reconfigure
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.

Notice:
This product has been successfully tested in a corrosion test according to IEC 60068-2-
