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
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. 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
connected to power supply.

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.

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.

Lynx DSS is equipped with internal termination that is configurable through software
in RS-422/485 mode. The following termination schemes are supported:

Termination
When the unit is powered-off or during reboot, any internal termination will be
disconnected from the signal lines.
Note: Due to that the port is configurable for both RS-232 and RS-422/485,
there are no fail-safe biasing available for RS-422/485 signals.
