1. Description
The SDW-500 is a series of Industrial Ethernet 5-port switches.
Several variations are available ranging from a version with five RJ-45 TX (copper) ports
to versions having two FX (fibre) and three TX ports.
All TX 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-500 series has been designed to meet high industrial specifications, providing
very high dependability in harsh environmental conditions.
Features:
… Flexible mix of TX (copper) and FX (fibre) interface
… TX shields individually isolated
… Wide DC power range 12–48 VDC
… Wide temperature range
… Redundant power
… Automatic MDI/MDI-X crossover
… LED indicators for Power, Speed, Duplex, Link and Traffic
… Port monitoring
… 35 mm DIN rail mounting
… SC, ST and LC fibre interface
… Multi (MM) and single mode (SM) fibre
Example of applications are:
… 5-port switch
… Fibre to copper converter
… Ethernet isolator, for STP network

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) and EN61000-6-4 (Industrial emission).
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 AC/DC
mains supply and all other electrical connections.
Installation:
This unit should only be installed by qualified personnel.
This unit should only be installed in a “restricted access area”, for example
a lockable cabinet where access is restricted to service personnel only.
This unit is intended for permanent connection to the AC/DC mains supply.
The power supply wiring must be sufficiently fused, and if necessary it must be
possible to disconnect manually from the AC/DC mains supply. Ensure compliance
to national installation regulations.
Units with the rated voltage exceeding 42.4 V peak or 60 VDC, are defined as
class I equipment with a protective earthing conductor terminal.
Units with the rated voltage up to 42.4 V peak or 60 VDC, are defined as class III
equipment and shall be separated from hazardous voltage by double or reinforced
isolation.
This unit uses convection cooling.To avoid obstructing the air flow around the
unit, follow the spacing recommendations (see Installation section).

6.3 DIP switch settings SDW-550
DIP-switches are accessible under the lid on top of the unit. DIP-switches are
used to configure the unit.
Warning!
Prevent damage to internal electronics from electrostatic discharges (ESD) by
discharging your body to a grounding point (e.g. use of wrist strap), before the
lid on top/front of the unit is removed.
Warning! Do not open connected equipment.
Prevent access to hazardous voltages by disconnecting the unit from AC/DC
mains supply and all other electrical connections.
NOTE
When configuration via DIP-switches, the settings of DIP-switches configure the unit only
after a reboot (power off/on).
To be observe when the DIP-switches will be 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.
… If auto-negotiation and auto MDI/MDI-X disabled all TX ports support MDI-X
configuration.
