SE3 Series Industrial Unmanaged Ethernet Switches User Manual
General Information
Overview
is user manual will help you install and maintain the Stride industrial Ethernet switches. Installation of
these devices is very easy and they will begin to operate as soon as they are powered up.
Operation
Unlike an Ethernet hub that broadcasts all messages out all ports, these industrial Ethernet switches will
intelligently route Ethernet messages only out the appropriate port. e major benets of this are increased
bandwidth and speed, reduction or elimination of message collisions, and deterministic performance when
tied with real-time systems.
ese industrial Ethernet switches can support 10BaseT (10 Mbps), 100BaseT (100 Mbps) or 1000BaseT
(Gigabit Ethernet) on their RJ45 ports. Each of these ports will independently auto-sense the speed and
duplex, mdi/mdix-crossover and polarity allowing you to use patch or crossover cables.
Some models include ber optic ports, or slots that accept SFP ber optic transceivers.
Security Considerations
When implementing any method of remote access to your equipment, you need to consider the security
exposure in order to minimize the risks to your processes and your equipment. Security should always be
carefully evaluated for each installation. Refer to “Appendix F: Security Considerations for Control Systems
Networks” for more information.
