Section 1 General Information
Overview
The Red Lion EL326 is a 26 port industrial Ethernet managed switch designed to meet the
extreme requirements of power substations, traffic control, railway and other harsh
environments. It combines the high performance and security of an enterprise-class switch
with rugged packaging and protected circuitry to meet the needs of the most demanding
applications.
This manual will help you install and maintain these industrial Ethernet switches.
Installation of these switches is very easy and they will begin to operate as soon as they
are powered up. Though these are fully managed switches, they will act as unmanaged
until they are configured otherwise. Refer to the separate software manual or management
guide for configuration of the advanced networking functionality and security.
Note: This manual only covers the installation and wiring of these switches. Refer
to the separate Management Guide for details on configuring and using any of the
management functions such as SNMP, RSTP, IGMP, VLANs, security, port
mirroring and much more.
Basic
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. The major
benefits of this are increased bandwidth and speed, reduction or elimination of message
collisions, and deterministic performance when tied with real-time systems.
These industrial Ethernet switches support 10BaseT (10 Mbps), 100BaseT (100 Mbps) and
1000BaseT (1000Mbps) on the first 24 ports via standard RJ45 connectors. These ports
will independently auto-sense the speed/duplex and mdi/mdix-crossover allowing you to
use straight or crossed-wired cables. Ports 21-24 are combination ports and also provide
SFP cages that accept industry-standard pluggable SFP transceivers of various types
including multimode, singlemode, long-haul, bidi and more. These pluggable SFP ports
support 100/1000BaseF (100/1000 Mbps) noise-immune fiber connections up to 120km.
