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 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.
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.
General Features
The general features list presented in Table 1-1 apply to these industrial Ethernet switches. Refer to the next section for a list of key features.

If the package contents are damaged:
1. Contact your carrier.
2. File any damage claims with the carrier.
Installing Mounting Brackets
There are many options for mounting the industrial Ethernet switches. Each switch is supplied with a standard set
of 19” rack mounting brackets. Optionally, mounting brackets for 23”, 24” and ETSI width racks are available.
These mounting brackets universally support the mounting hole spacing per the EIA (1.25”), ETSI (25mm) and
WECO (1.00”) standards. Refer to the mechanical diagram in Figure 1-5 on page 17 for details.
There are eight threaded inserts (see red arrows in Figure 1-2) on each side of the switch that allow the brackets to
be mounted in numerous positions for the best fit in your rack. The brackets also have extra holes (see blue arrows
above) allowing them to be shifted right or left 1/2 inch. Use the supplied screws to mount the bracket in the
desired position. Plastic screws are also provided to plug the unused holes. See below for possible mounting positions.
Figure 1-2. Threaded Inserts
The brackets are shown mounted flush with the front of the switch in Figure 1-3 (on the left) and the brackets
shown mounted so the front of the switch is setback 1/2 inch (on the right).
Figure 1-3. Brackets Front Flush or Setback Mounted
For the most durable mounting use two brackets on each side, front and back (as shown in Figure 1-4). This
mounting option is ideal for applications requiring the highest shock and vibration resistance.

Thermal Considerations
The EL326 switches are designed to operate from -35 to +80˚C when they are installed properly. The switch is
cooled via conduction and radiation. There are no fans. Instead there are various heat-sinks inside the switch to
conduct the heat from the components to the heavy-gauge aluminum case. The heat is then dissipated from the
case via radiation to the surrounding air.
Rack Mounting
When the switch is rack mounted, for best heat dissipation it is recommended that there be approximately 1/2RU or
more of free air space above and below the switch (as shown in Figure 1-6). This allows the heat to radiate to the
air. Any moving air in your rack will improve dissipation of the switch generated heat.
Note: An air gap is not absolutely necessary but highly recommended when you know that the
switch will experience high heat (> 60˚C) for extended periods of time.
Figure 1-6. EL326 Rack Mounting Recommendation
Note: If your space is limited and you must choose between an air gap on the bottom versus an air
gap on the top it is better to have the air gap on the top
BTU / Hour
The power consumption of the switch can be as much as 120 Watts with all ports linked and active. Based on this,
the heat dissipation can be as much as 408 BTU per hour. Please plan your system accordingly.

Power and Output Wiring Revised 2015-08-05
Section 3 Power and Output Wiring
WARNING: : Please read this section fully before connecting your power input or alarm
output! The unit must be powered down and the power plug removed before any wiring
is done to the power plug. Otherwise, there is a risk of electrical shock if the rules and
warnings in this manual are not properly adhered too.
Introduction and Overview
The EL326 switches are available with several power options including dual power supplies that can keep the
switch running when there is a power input failure or internal power supply failure. Refer to Table 1-1 for the available standard power supply options.
Table 1-1.
OPTION INTERNAL POWER SUPPLY POWER SOURCE TO P1/P2 CONNECTOR

Special Order Options:
Other power input options may be available. Contact Red Lion for details.
Redundancy Operation
The AA and DD power supply options offer dual redundant power supplies built into the switch. This protects your
system from both power input failures and internal power supply failures. Please note that the AA and DD have different default modes of operation
AA Option Operation
The AA option provides dual high voltage power inputs. These inputs are load shared so each input shares around
50% of the load under normal operating conditions. If a power input or supply fails then the other one will handle
100% of the load.
Sixnet Series EL326 Switch Hardware Guide 19
Power and Output Wiring Revised 2015-08-05
DD Option Operation
The DD option provides dual low voltage power inputs. These inputs operate in a primary/backup scheme. The P1
input should be connected to the primary power source and the P2 input to the backup power source (such as a
battery). Under normal operating conditions all the power is drawn from the P1 input and supply. Only if P1 fails is
power drawn from the P2 backup input and supply.
Note: These default modes of operation can be changed at the factory. Contact Red Lion for
details.
CAUTION: Make certain you know what type of power your switch accepts and ensure
your input power is within the ranges as defined in this section. Applying the wrong
input power may result in damage to your switch.
Safety Grounding
For the highest electrical safety the EL326 switches are provided with several grounding points. First, there are two
green ground screws (see Figure 1-1) that attach directly to the switch case. These screws can be used to provide
a NEBS compliant safety ground. Please follow all the NEBS grounding rules and your own local requirements
(which are not documented in this manual) to ensure the safe operation of the switch. Alternatively, the power plug
has a chassis ground terminal (#4) that can be used to safety ground the switch. This terminal is internally tied to
the switch case. In addition, there is a ground terminal for each power input. Use these to terminate the ground
wire for each of your power inputs.

Power and Output Wiring Revised 2015-08-05
Note: The 2 Safety Guard Screws are designed to be used with Ring Lug Terminals. Do not wrap
ground wire around either of the safety ground screws.
WARNING: It is recommended you make your safety ground connections first before
connecting any power to the switch. Ensure that all power is off before making any
power or ground connections to the switch.
Power Labeling
The power headers and/or plugs are labeled to guide you in properly connecting your power (see Figure 1-2).
Make sure to reference this labeling when wiring your switch to ensure you are connecting the appropriate power
to the correct terminals (see Figure 1-3). If your switch does not have dual power inputs then do not connect anything to the terminals labeled Power 2. The power header/plug connectors are rated for 300V, 10A and 105C.

AC Power Systems
For AC powered systems the terminals will be labeled as “+/L” for Line (aka Hot), “-/N” for Neutral and the chassis
ground symbol for ground. Connect your AC power input as correspondingly. Typically the Line (Hot) lead is colored black or brown, the Neutral lead is colored white or blue and the ground is green or green/yellow.
Positive (+) DC Power Systems
For positive power systems (such as +24 VDC) put the positive lead on the terminal marked “+/L” and the return (or
ground) lead on the terminal marked “-/N“. If there is a chassis, earth or safety ground lead then put it on the associated terminal marked with the chassis ground symbol.
Negative (-) DC Power Systems
Both the power option ”A” and “D” support negative power systems. If your power is negative (such as -48 VDC)
then you must put the most positive lead on the “+/L” terminal. Always use a voltmeter to verify which lead is more
positive. Then put the more negative lead on the “-/N” terminal. If there is a chassis, earth or safety ground lead
then put it on the associated terminal marked with the chassis ground symbol.
Reverse Polarity Protection
The “D” option power inputs are reverse polarity protected. This means that if you swap the + and – leads then the
switch will not be damaged. However, the switch will not operate when wired with the polarity reversed.
“OK” Alarm Output
The switches have an “OK” alarm output that can be tied to a PLC input, an alarm indicator (visible or audible) or
other device to indicate when there is an alarm condition (such as the loss of a power input). The alarm output is a
Form C relay with a normally open (NO), normally closed (NC) and common (C) screw terminal. Apply an appropriate power source to the common (C) terminal.
Alarm Output Ratings:
• Maximum voltage = 250 VAC or 30 VDC
• Maximum current = 2 A @ 30 VDC or 250 VAC
• Minimum load = 10 mVDC, 10 μA
The alarm relay operates as described in Table 1-2 and is wired as in Figure 1-4.

Communication Ports Wiring Revised 2015-08-05
Section 4 Communication Ports Wiring
Introduction
The EL326 switches provide connections to standard Ethernet devices such as PLCs, Ethernet I/O, industrial computers and much more. Three types of communication ports are on these switches: RJ45 (copper) Ethernet ports,
SFP (pluggable) Ethernet ports and console (serial RS232) ports.
Gigabit RJ45 Ports 1-24
The EL326 switch has 24 Gigabit RJ45 copper ports that accept 10/100/1000 Mbps twisted pair cabling (shown in
Figure 1-1). Use data-quality (not voice-quality) twisted pair cable rated category 5E (or better) with standard RJ45
connectors. Straight through or crossover RJ45 cable can be used regardless of the device the switch is being connected to as all the ports are capable of auto-mdi/mdix-crossover detection.
Figure 1-1. Gigabit RJ45 Copper Ports
The RJ45 Ethernet port connector bodies on these switches are metallic and are connected to the Chassis GND
terminal. Therefore, shielded cables should be used to provide further protection from electrical noise and interference. Ideally, to prevent ground loops, the cable shield should be tied to the metal connector body at one end of the
cable only. Electrical isolation is also provided on the Ethernet ports for increased reliability.
Note: The use of shielded cables is required to fully meet the requirements of EMC standards.
Table 1-1 is provided for reference only as either cable wiring scheme will work.

Ports 21-24 (see Figure 1-2) are combination gigabit ports that provide both RJ45 and SFP (Small Form-factor
Pluggable) connectors. This allows using the RJ45 connectors for twisted pair copper connections or use the
SFP connectors for fiber optic connections. The SFP connectors support 100 Mbps and 1000 Mbps fiber optic
transceivers for links up to 120 Km (74 miles).
Figure 1-2. Gigabit / SFP Ports 21-24
Note: For each of these ports you can only use one of the connectors (RJ45 or SFP) at a time. If
you connect to both at the same time then neither connector may work.
Ports 21 through 24 offer flexible SFP (Small Form-factor Pluggable) connectors that support 100 or 1000 Mbps
fiber optic SFP transceivers. On these 4 ports you can mix and match different types of SFP fiber transceivers as
desired.
Sixnet Series EL326 Switch Hardware Guide 26
Communication Ports Wiring Revised 2015-08-05
SFP Transceivers
The SFP transceivers just plug into the SFP cages. To lock them in place lift the locking arm as shown in Figure 1-
3. To remove a transceiver, first pull down on the locking/release arm and then pull the transceiver out. The transceivers are “hot-swappable” meaning they can be plugged in or removed when the switch is powered.
Figure 1-3. Typical SFP Transceiver
SFP Transceiver Fiber Wiring Guidelines
The SFP ports accept fiber optic SFP transceivers. These transceivers are sold separately and are available as
multimode, singlemode, long-haul (up to 120 Km (74 miles) or more), BiDi (bidirectional), WDM and other special
types. They typically are offered with an LC style fiber connector (see Figure 1-4). Refer to the data sheets for
these transceivers for more details.
Figure 1-4. Typical Fiber SFP Transceiver and Dual-LC Cable
Use standard fiber optic wiring techniques (not covered by this manual) to make your connections. The corresponding LED will be ON solid or flashing when you have made a proper connection.
Duplex Operation
The RJ45 ports will auto-sense for Full or Half duplex operation, while the fiber ports default to full duplex operation
or can be configured for Full or Half duplex. Refer to the software user manual for details on the software configuration options.
Sixnet Series EL326 Switch Hardware Guide 27
Communication Ports Wiring Revised 2015-08-05
Verifying Connectivity
After all Ethernet and/or fiber connections are made, check the LED’s corresponding to the ports having a connected device. Ensure the LED is on or blinking for each port in use. If a port LED is off, go back and check for
connectivity problems between the port and the network device connected to that port.
Console Port Management
The switch can be software configured via an RJ45 RS232 console port (see Figure 1-5). This manual only details
on connecting to this port. Refer to the software manual for details on how to configure the switch via this port.
Figure 1-5. RS232 RJ45 Port
The RJ-45 serial port on the switch’s front panel is used to connect to the switch for out-of-band console configuration. The on-board configuration program can be accessed from a terminal or a PC running a terminal emulation
program. The console cable is an RJ45 to DB9 adapter included with the unit, part number EL326CNSCBL. The
pin assignments used to connect to the serial port are provided in Table 1-2.

Connecting Switches in a Stack
In line-topology stacking there is a single stack cable connection between each switch that carries two-way communications across the stack. In ring-topology stacking, an extra cable is connected between the top and bottom
switches forming a “ring” or “closed-loop.” The closed-loop cable provides a redundant path for the stack link, so if
one link fails, stack communications can still be maintained.
The stack cables are connected between switches in a stack. Each stacking connection is a 48 Gbps full-duplex
high-speed serial link using proprietary stacking cables. The switch supports a line- and ring-topology stacking
configuration, or can be used stand alone. To ensure minimal disruption in case a unit or stacking cable fails, we
recommend always use a ring-topology.
Sixnet Series EL326 Switch Hardware Guide 28
Communication Ports Wiring Revised 2015-08-05
Switch Stack Connection Procedure
To connect up to eight switches in a stack refer to Figure 1-6 and perform the following steps:
1. Plug one end of the stack cable (ordered separately) in the Down (right) port of the top unit.
2. Plug the other end of the stack cable into the Up (left) port of the next unit.
3. Repeat steps 1 and 2 for each unit in the stack. Form a simple chain starting at the Down port on the top unit
and ending at the Up port on the bottom unit (stacking up to 8 units).
4. (Optional) To form a wrap-around topology, plug one end of a stack cable into the Down port on the bottom
unit and the other end into the Up port on the top unit.
Figure 1-6. Switch Stack Connections
Installing Optional 10G Switch Module
To install an optional 10G module into the switch refer to Figure 1-7 and perform the following steps:
1. Remove the blank metal plate (or a previously installed module) from the appropriate slot by removing the two
screws with a flat-head screwdriver.
2. Before opening the package that contains the module, touch the bag to the switch casing to discharge any
potential static electricity. Also, it is recommended to use an ESD wrist strap during installation.
3. Remove the module from the anti-static shielded bag.
4. Holding the module level, guide it into the carrier rails on each side and gently push it all the way into the slot,
ensuring that it firmly engages with the connector.
5. If you are sure the module is properly mated with the connector, tighten the retainer screws to secure the
module in the slot.
6. The Module LED on the switch’s front panel should turn green to confirm that the module is correctly installed
and ready to use.

Hi-Pot Testing and Maintenance Revised 2015-08-05
Section 5 Hi-Pot Testing and Maintenance
Introduction
This device is designed to withstand a high-potential “hi-pot” (dielectric) test up to 2000 Vrms according to IEEE
1613. However, the surge protection circuitry must be bypassed before performing this test.
CAUTION: This device is 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. The switch’s surge
protection circuitry may be damaged if you do not disconnect it while performing a “hi-pot” test.
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.
Hi-Pot Slot
The switch features a unique method for temporarily disconnecting the surge protection circuitry. An opening in the
switch case called the “Hi-Pot Slot” provides for this capability (see Figure 1-1).

Hi-Pot Testing and Maintenance Revised 2015-08-05
Hi-Pot Test
To perform a Hi-pot test please follow the following steps:
1. Locate and expose the hi-pot slot. It is found on the side opposite the Ethernet ports. You may need to
remove the power plug or power cover.
2. Acquire or make a hi-pot slot card. You can do this in several ways as follows:
a. Contact Red Lion and ask to be sent a complimentary “hi-pot slot card”.
b. Use a credit-card-sized plastic card (without raised lettering so not an actual credit card), laminated busi-
ness card or other similar plastic card. The dimensions should be as shown in the step 2 figure.
c. Cut out a card from 0.02” to 0.03” plastic (such as ABS or polycarbonate). The dimensions should be as
shown in the step 2 figure.
Hi-Pot Card
from Red Lion
3. Insert the card into the slot as shown in the images below. You may need to angle the card up a little to get it
started. Once it is started then push the card into the slot perpendicular to the face of the switch. As you push
the card in, about half way you should feel some resistance, this is normal. Push the card in until it either
stops or there is only about ¼” left sticking out. See images below.

4. With the card in place you can now perform the hi-pot (dielectric) test.
CAUTION: Make sure to remove the card when you are done testing. If you leave the
card in place during normal operations then your switch will not be fully protected from
surges.
