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 specifications 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.
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).
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 connected to power supply.
Class 1 Laser Product
Do not look directly into fibre optical fibre port or any connected fibre although
this unit is designed to meet the Class 1 Laser regulations.
Care recommendations
Follow the care recommendations below to maintain full operation of unit and to fulfil
the warranty obligations.
This unit must not be operating with removed covers or lids.
Do not attempt to disassemble the unit. There are no user serviceable parts inside.
Do not drop, knock or shake the unit, rough handling above the specification may cause
damage to internal circuit boards.
Do not use harsh chemicals, cleaning solvents or strong detergents to clean the unit.
Do not paint the unit. Paint can clog the unit and prevent proper operation.
Do not expose the unit to any kind of liquids (rain, beverages, etc). The unit is not water-
proof. Keep the unit within the specified humidity levels.
Do not use or store the unit in dusty, dirty areas, connectors as well as other mechanical
part may be damaged.
If the unit is not working properly, contact the place of purchase, nearest Westermo dis-
tributor office or Westermo Tech support.
Fibre connectors are supplied with plugs to avoid contamination inside the optical port.
As long as no optical fibre is mounted on the connector, e.g. for storage, service or
transportation, should the plug be applied.

Description
Lynx is a range of Fast Ethernet (100Mbit) or Gbit Ethernet switches consisting of three
different function levels and four different type approvals, giving you the ability to select
the perfect switch for your application providing optimum functionality at the best value.
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 faliure.
That is why the Lynx-series 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. The Lynx-series 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 Lynx-series in order to achieve determinism
for real time critical applications. The Lynx-switches 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.

Optical Power Budget
The allowed link length is calculated from the optical power budget (OPB), the available optical
power for a fibre-optic link, and the attenuation of the fibre, comprising losses due to in-line
connectors, splices, optical switches and a margin for link ageing (typical 1.5 dB for 1300 nm).
The worst-case optical power budget (OPB) in dB for a fibre-optic link is determined by the difference between the transmitter’s output optical power (min) and the receiver input sensitivity (max).

NOTE! Railway installation close to the rails.
For a cable located inside 3 m boundary and connected to this
port, the use of shielded cable is recommended, this is to minimise the risk of interference. The cable shield should be properly connected (360°) to an earthing point within 1 m from
this port. This earthing point should have a low impedance connection to the conductive enclosure of the apparatus cabinet,
or similar, where the unit is built-in. This conductive enclosure
should be connected to the earthing system of an installation
and may be directly connected to the protective earth.

The Lynx 300/1300 and 400/1400 have support for redundant ring protocols. The Fast
Reconfiguration of Network Topology (FRNT) protocol handles fast reconfiguration in
switched ring topologies. When rapid convergence in case of link or switch failure is
required, FRNT becomes the protocol of choice when it comes to layer-2 resilience and
robustness.
To set-up a FRNT ring, all switches must be connected according to one of the possible
configurations stated below. When the switches are connected each switch must be configured through the web interface.
Connecting the switches in a FRNT ring
There are three possible ways of configuring a FRNT ring:
1. Ring using fibre cables only
2. Ring using copper cables only
3. Ring using fibre and copper cables alternately
1. FRNT ring using fibre cables
The rules are as follows:
• Switch port 7 and 8 are FRNT fibre ports
• Always connect port 7 to 8, 7 to 8, 7 to 8... throughout the ring
• Do not connect 7 to 7 or 8 to 8!

Managing FRNT settings via the web interface
Menu path: Configuration > Redundancy Protocol
On the FRNT configuration page you will be presented to the current settings for FRNT
on your switch, see below. You may change the settings by editing the page.
Focal Point
The focal point is the unit in the ring which is responsible for making decisions on topology change. Check this box if this unit should take the role as focal point in the FRNT
ring. If not checked, the unit will act as a member unit.
Port 1/Port 2
FRNT requires two ports to be assigned FRNT-ports. These are connected to peer
units participating in the FRNT ring. Select the two ports connected to other units in
the FRNT ring. Switch port 7 are defined as FRNT port 1 and switch port 8 are defined
as FRNT port 2 by default. The FRNT ports setting must be configured to connect
alternately. FRNT port 1 on one switch should always connect to FRNT port 2 on next
switch throughout the ring. Never connect FRNT port 1 to FRNT port 1 or FRNT port
2 to FRNT port 2.
Click the "Apply" button to confirm changes made to the Redundancy Protocol settings.
The unit needs to be restarted before changes can take affect.
