SE3-USER-M 2 1st Edition, Dec. 2023
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 benets 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.
Class I Division 2 Hazardous Location Installation and Operation
ese are open-type devices. Units rated for hazardous locations are meant to be installed in an enclosure
which is only accessible with the use of a tool and suitable for the environment when installed in Class 1,

Safety Precautions
CAUTION: IF THE DC VOLTAGE IS SUPPLIED BY AN EXTERNAL CIRCUIT, PLEASE USE A PROTECTION DEVICE ON THE
POWER SUPPLY INPUT. SUPPLY POWER FROM A UL LISTED INDUSTRIAL USE POWER SOURCE.
Warning Labels
e caution label and hot surface warning label mean that you
should check the certain information on user manual when
working with the device.
FCC Statement
is equipment has been tested and found to comply with the limits for a Class-A digital device, pursuant
to Part 15 of the FCC rules. ese limits are designed to provide reasonable protection against harmful
interference in a residential installation. is equipment generates, uses, and can radiate radio frequency
energy. It may cause harmful interference to radio communications if the equipment is not installed and
used in accordance with the instructions. However, there is no guarantee that interference will not occur in
a particular installation. If this equipment does cause harmful interference to radio or television reception,
which can be determined by turning the equipment o and on, the user is encouraged to try to correct the
interference by one or more of the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and receiver.
•Connect the equipment into an outlet on a circuit dierent from that to which the receiver is connected.
•Consult the dealer or an experienced radio/TV technician for help.
NOTE: Modications to this equipment will void the user’s authority to operate the equipment.
CE Mark Warning
is is a Class-A product. In a domestic environment this product may cause radio interference in which
case the user may be required to take adequate measures.

SE3 Series Industrial Unmanaged Ethernet Switches User Manual
Redundant Power Inputs
All SE3-series industrial Ethernet switches have dual redundant power inputs. Connecting two
independent power sources reduces the risk of down time resulting from power supply failure.
For information on wiring power to the industrial Ethernet switches, please see "Power Wiring" on page 14.
Power Fault Alarm
Most of the SE3-series industrial Ethernet switches oer a power fault alarm contact to signal loss of power.
e alarm is a normally open contact that is held closed by the presence of power on both power inputs.
On loss of one or both power sources, the alarm contact will open. For proper operation of the alarm
contact when using a single power input, jumper the two power inputs together. For information on wiring
the power fault alarm contact, please see "Alarm Wiring" on page 15.
DIP Switches (Model SE3-SW5UG-1P-T Only)
Model SE3-SW5UG-1P-T has two DIP switches, located on the front of the unit.
1 2
ON SE3-SW5UG-1P-T DIP Switch Settings
DIP Switch Description ON OFF
1Enables or disables Energy Efcient Ethernet. Enable Disable
2 SFP module port speed 100Mbps Module Native Speed
NOTE: A change in the dip switch settings will not take e󰀨ect until the switch is power cycled. So, if a setting is
changed while the device is powered, the old setting will remain active until power is removed and reapplied.
SFP module port speed:
Model SE3-SW5UG-1P-T can optionally force a compatible Gigabit SFP module to operate at 100Mbps.
e DIP switch should normally be in the OFF position for both 1Gbps and 100Mbps SFP modules, to
allow them to operate at their native speed. Set the switch to the ON position to force a 1Gbps module to
operate at 100Mbps. is may be useful, for instance, to connect to legacy 100Mbps equipment without
requiring purchase of an additional SFP module. is feature may not be compatible with all SFP modules,
but does work with the Gigabit SFP modules available at www.automationdirect.com.
Energy-Eicient Ethernet (EEE):
Energy-Ecient Ethernet (EEE) is a set of enhancements dened by the IEEE 802.3az standard.
Its primary objective is to curtail power usage during periods of reduced data activity or idleness. By
dynamically adapting power consumption according to actual data trac demands, EEE reduces power
consumption by up to 30%.

SE3 Series Industrial Unmanaged Ethernet Switches User Manual
Mounting
e SE3 series switches can be DIN rail mounted or panel wall mounted. Each switch is shipped with all
necessary brackets for either mounting option.
DIN Rail Mounting
e SE3 switches can be mounted on a standard 35 x 7.5 mm height DIN rail (Standard: CENELEC
EN50022) installed either vertically or horizontally.
Installing DIN rail bracket:
Most SE3 switches are shipped with DIN rail brackets preinstalled.
For the IP67 model, attach the DIN rail bracket to the switch using
the supplied hardware, as shown in the gure to the right.
DIN rail mounting steps:
1. Hook top back of unit over the DIN rail.
2. Push bottom back onto the DIN rail until
it snaps into place.
DIN rail removal steps:
A. Push the unit down to free the bottom
of the DIN rail.
B. Rotate the bottom of the unit away from the
DIN rail.
C. Unhook top of unit from DIN rail.

Wall Mounting
Follow the steps below to mount the switch using the wall mounting bracket. Bracket details and hole
patterns dier between models.
Removing the DIN rail bracket
All SE3-series switches other than the IP67 model are shipped with DIN rail mounting brackets
preinstalled. is bracket must be removed to mount the switch directly onto a panel wall.
ere are several styles of DIN rail bracket in use across the SE3 product line. In all cases, remove the DIN
rail mounting bracket by loosening several easily accessible screws.
Attaching the wall mounting bracket
Attach the wall mounting brackets on the top and bottom of the switch using the supplied hardware.
Specic mounting hole locations vary between models.
is step is unnecessary for Model # SE3-SW5U-N67-T, whose wall mounting brackets are an integral
part of the housing.
Mounting the switch to panel wall
Place screws in the panel wall based on the positions of the slotted screw holes on the mounting brackets
and attach the switch to the wall.
