Ethernet Switches Work Around Line Breaks

By DE Editors

New CyberResearch (Branford, CT) ESW 405-series ring-redundant 10/100Mbps Ethernet switches read the header frame of each Ethernet packet so they know how and where to forward it. This capability both provides redundancy and increases available bandwidth.

Rugged DIN-mount ESW 405 switches from CyberResearch come with a heavy-duty aluminum case (ESW 405M) or an industrial plastic case (ESW 405P). Both styles 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. Each ESW 405 switch has two independent DC power supplies for enhanced reliability. Legends printed on the sides of the cases give switch settings and LED meanings.

One limitation of conventional Ethernet networks is that line breaks cut off contact with downstream devices. CyberResearch ESW 405 switches detect a break in the ring and route relevant signals around it; more rings provide more protection and double rings protect against a simultaneous single break in each ring.
