1. Description
The SDW-550 is an Industrial Ethernet 5-port switch.
All ports support auto-negotiation, but DIP-switches also allow speed and duplex
configuration of any individual TX port. It is also possible to set up one port to
monitor traffic to/from the switch.
The SDW-550 has been designed to meet high industrial specifications, providing
very high dependability in harsh environmental conditions.
Features:
… TX shields individually isolated
… Wide DC power range 12-48 VDC
… Wide temperature range
… Automatic MDI/MDI-X crossover
… LED indicators for Power, Speed, Duplex, Link and Traffic
… Port monitoring
… 35 mm DIN rail mounting
… Enable or disable of flow control
Example of applications are:
… 5-port switch
… Ethernet isolator, for STP networks

2. Safety
General:
Before using this unit, 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.
Before installation, maintenance or modification work:
Prevent damage to internal electronics from electrostatic discharges (ESD) by
discharging your body to a grounding point (e.g. use of wrist strap).
Prevent access to hazardous voltages by disconnecting the unit from DC mains
supply and all other electrical connections.
When installed, should the unit and it's wiring be separated from hazardous
voltage by double or reinforced insulation.
Installation:
This unit should only be installed by qualified personnel.
This unit should only be installed in a "restricted access area", for example a lock-
able cabinet where access is restricted to service personnel only.
This unit is intended for permanent connection to the DC mains supply.
The power supply wiring must be sufficiently fused, and if necessary must be pos-
sible to disconnect manually from the DC mains supply. Ensure compliance to
national installation regulations.
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.
This unit uses convection cooling.To avoid obstructing the air flow around the
unit, follow the spacing recommendations (see Installation section).

3. Approvals
Conformity with the Directive 73/23/EEC Low Voltage Directive – LVD has been
assessed by application of the standard EN 60 950.
Conformity with the Directive 89/336/EEC Electromagnetic Compatibility (EMC)
has been assessed by application of standards EN 61000-6-2 (industrial immunity)
and EN 61000-6-3 (residential emission).
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,nearestWestermo dis-
tributor office orWestermoTech support.

Configuration
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.
Flow control is possible to enable or disable with DIP-switch.
