1. Description
The SD-300 is a serie of Industrial Ethernet 3-port switches.
Several variations are available ranging from a version with three RJ-45 TX (copper) ports
to versions having two FX (fibre) and one TX port.
All TX ports support auto-negotiation, but DIP-switches also allow speed and duplex
configuration of any individual TX port.
The SD-300 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) interfaces
• TX chassies individually isolated
• Wide DC Power Range 18–48 VDC
• LED indicators for Power, Speed, Duplex, Link and Traffic.
• 35 mm DIN rail mounting
Example of applications are:
• 3-port switch
• Fibre repeater, with service port
• Fibre to copper converter
• Singlemode to Multimode fiber converter

3. Approvals
Conformity with the Directive 89/336/EEC (Electromagnetic compatibility)
has been assessed by application of standards EN 61000-6-2 (industrial immunity)
and EN 61000-6-3 (residental 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
insulation.
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
DIP-switches are accessable under the lid on top of the unit. DIP-switches are
used to configure the modem.
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 modem 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).
