Fiber Optic Safety
WARNING: When using fiber optic ports, never look at the transmit laser, fiber TX port or fiber
cable ends while the switch is powered on. It is highly recommended to keep the rubber fiber plugs
inserted when the fiber port is not being used.
Hi-Pot (Dielectric) Testing
CAUTION: The EL326-AO/AA-1 devices are designed to withstand a high-potential “hi-pot”
(dielectric) test up to 2000 VAC or 2800 VDC (1 minute), or 2400 VAC or 3300 VDC (1 second)
according to IEEE 1613. However, the surge circuitry must be bypassed before performing this
test. See Section 5 for details.
CAUTION: The EL326-DD/DO-1 devices are designed to withstand a high-potential “hi-pot”
(dielectric) test up to 500 VAC (1 minute) or 707 VDC (1 minute) on the inputs (P1 and P2)
according to IEEE 1613. However, the surge circuitry must be bypassed before performing this
test. See Section 5 for details.

Section 1 Introduction and Specifications
Introduction
The Red Lion Sixnet Series 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 per-
formance 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.
Unlike an Ethernet hub that broadcasts all messages out all ports, these industrial Ethernet switches will intelli-
gently 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 combi-
nation 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.
General Features
The general features list presented in Table 1-1 apply to these industrial Ethernet switches. Refer to the next sec-
tion for a list of key features.
