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.

66644-2214
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.

Care recommendations
Follow the care recommendations below to maintain full operation of product and to
fulfil 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.
Cleaning of the optical connectors
In the event of contamination, the optical connectors should be cleaned by the use of
forced nitrogen and some kind of cleaning stick.
Recommended cleaning fluids:
• Methyl-, ethyl-, isopropyl- or isobutyl-alcohol
• Hexane
• Naphtha
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 the 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.

DIP switch settings SDW-550
DIP-switches are accessible under the lid on top of the product. DIP-switches are used
to configure the product.
NOTE
When configuration via DIP-switches, the settings of DIP-switches configure the product
only after a reboot (power off/on).
Observe this when the DIP-switches are configured:
… Speed and duplex setting only valid when auto-negotiation is disabled.
… When monitoring selected all outgoing packets from the switch is also copied to the
port 1.
… Speed and duplex switch settings are ignored for FX ports.
… If auto-negotiation and auto MDI/MDI-X disabled all TX ports support MDI-X
configuration.
