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.
