CyberResearch is proud to introduce our new ESW 405 series
of DIN-mount ring-redundant 10/100Mbps Ethernet switches. These
switches read the Header frame of each Ethernet packet, so they
know how and where to forward each packet. This capability
provides redundancy and increases available bandwidth.
These rugged switches come with a heavy-duty aluminum case
(ESW 405M) or an industrial plastic case (ESW 405P). Both units
are functionally identical and include five RJ-45 Ethernet ports as
well as an RS-232/485 port on a single RJ-45 connector, so you can
communicate with both serial and Ethernet devices or peripheral
switches like our ESW 205 and ESW 208 (see page 148). Power and
output relays are connected via screw terminals. Each unit has
two independent DC power supplies for enhanced reliability.
Legends printed on the sides of the module give switch settings
for configuration and redundancy time, as well as LED meanings.

Dual independent rings with only a single master switch
One ESW 405 switch can support two independent Ethernet rings.
Linked rings for dual redundancy: Any switch can address any other switch
in either ring, as long as there is no more than one line break in each ring.

How do Ring Ethernet Switches Work?
Single redundant ring with one master switch
Single ring is formed by three or more ESW 405 redundant switches,
peripheral switches can be cost-effective ESW 205 or ESW 208 models (pg. 148).

Ethernet is an excellent long-distance and high-speed
communication protocol, but cable breaks in conventional
networks cut off contact with downstream devices. Our
intelligent ring-redundant Ethernet switches work around such
breaks by detecting them and rerouting relevant signals to the
other leg of the ring, as shown in the diagrams below.
For additional protection, just add more rings. A single
ring protects against a single break between any two switches.
A double ring protects against a single break in each ring, but
not against damage to the central switch joining the two rings.
Dual-redundant rings add protection against damage to any
of the four central switches joining the two primary rings.
