Safety Information
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 and operated by qualified service
personnel and installed into 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 crosssectional area
of at least 4 mm2.
If the product does not have a protective earthing terminal,
then the DIN-rail 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 - HAZARDOUS VOLTAGE
Do not open an energized product. Hazardous voltage may occur
when connected to a power supply.
WARNING - PROTECTIVE FUSE
The power supply wiring must be sufficiently fused. 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.

66644-2240
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 - CLASS 1 LASER PRODUCT
Do not look directly info a fibre optical port or any connected
fibre, although the product is designed to meed the Class 1 Laser
regulations and complies with 21 CFR 1040.10 and 1040.11.
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 - FIBRE OPTIC HANDLING
Fibre optic equipment need special treatment. It is 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.

Auto configured (auto-negotiation) or manually setting of speed and duplex of individual TX port, by DIP-switches. Port
mirror function is possible to set with DIP-switch. With the port mirror function active the switch will copy all outgoing
traffic to port 1. This can be used to monitor all traffic going out from the switch. Packets may be discarded if the total
throughput exceeds the port speed of port 1.

Description
The SDW-541-F1G-T4G is an unmanaged 5-port switch with one SFP fibre port
supporting 100 Mbit/s or Gbit Ethernet, and four copper ports supporting 10/100 Mbit/s
or Gbit Ethernet. The Westermo range of 100 Mbit or Gbit Small Form-factor Pluggable
(SFP) transceivers are available as multimode, singlemode or Bi-Di transceivers with
distance up to 120 km.
The SDW-550-T5G is an unmanaged 5-port
switch with five copper ports, all supporting 10
Mbit/s, 100 Mbit/s or Gbit Ethernet. Both are
designed for easy use in heavy duty industrial,
maritime and rail trackside applications. The
units support 802.1Q long packets which allow
all standard industrial Ethernet protocols to
be used.
The units are designed for use in industrial
applications with dual 9.6 to 57.6 VDC power
input. The unique “tri-galvanic” isolation
provides isolation between all ports, power
supply and between each chassis screen
avoiding ground loop currents. The IP21
rating ensures that the unit can be installed in
locations where condensed water may occur.
Only industrial grade components are used
which gives an MTBF of 1.182.000 hours for
the SDW-541-F1T4G and 1.121.000 hours for
the SDW-550-T5G and thus ensures a long
service life. A wide operating temperature
range of –40 to +74 °C (–40 to +165 °F) can
be achieved with no moving parts.
The units have been tested both by Westermo and external test houses to meet EMC,
isolation, vibration and shock standards, all to the highest levels suitable for heavy
industrial, trackside and maritime environments.
Network diagnostics are simplified with the inclusion of port mirroring on one port
allowing data flow through the switch to be monitored using a network analyzer. All
five ports can have data rate and flow control locked by DIP switch which can eliminate
problems with old legacy Ethernet equipment that is unable to support auto negotiation.
