ES42 Series Edge Switches
Installation and User Guide (05/05)
Example 2: ES42H and CSN14H
In this industrial networking application, the new PLC units are deployed on a network
expansion, and each PLC required one (or two for redundancy) Ethernet ports to carry
status and control data to the control center. The ES42H and CS14H provide a good
solution with their multiple options and hardened features. The two Fiber ports on the Edge
switches are ideal for secure data communications over long distances. Built with high-
grade components, efficient cooling techniques and having no openings for dirt to enter, the
ES42 Series Edge Switches provide the very effective solution for this need. The CS14H
offers additional and affordable fiber connectivity to the ES42H where needed.
