3.2.2 IONet Switches
IONet switches are unmanaged, fully switched, and full-duplex to prevent collisions. They provide data buffering and flow
control during the critical input scan. Only industrial grade switches that meet the codes, standards, performance, and
environmental criteria for industrial applications are used for the IONet. GE industrial Ethernet 10/100 IONet switches
(ESWA and ESWB) have an operating temperature of -40 to 70 °C (-40 to 158 °F), have provisions for redundant 18 to 36 V
dc power sources (200/400 mA), and can be DIN-rail mounted. The switches also provide LEDs to indicate the status of the
IONet link, speed, activity, and duplex.
