2.1 Device Setup
Before using the switch, please follow the steps below to finish the device installation.
1. Hold the switch uprightly;
2. Place the switch on the DIN rail at an angle with the clip at the top of the DIN rail bracket
fit into one side of the DIN rail;
3. Push the switch down to compress the spring of the bracket;
4. Release the switch when there is enough space for the downside of the DIN rail bracket
to fit the other side of the DIN rail;

Vantron | Embedded in your success, Embedded in your better life
World-leading provider of embedded/IoT products and solutions
S105 Industrial Switch | User Manual 15 www.vantrontech.com
5. Gently swing the switch to make sure the switch is fastened on the DIN rail;
6. Insert one end of an Ethernet cable into any RJ45 port of the switch and the other end
into a switch or server to connect the switch to the network;
7. Use another Ethernet cable to connect a client device to another RJ45 port of the
switch when necessary;
8. Insert the terminal end of the DC power connector into the power terminal of the
switch and the other end into the power cord;
9. Plug the power adapter into a power outlet that meets the supply voltage requirement
(12V to 48V DC) to turn on the device.
If you are using the switch as a PSE to supply power to devices over Ethernet, please
connect the switch to an outlet that supplies 48V-53.2V DC.
2.2 Starting the Device
The S105 unmanaged industrial switch offers a plug-and-play solution, and users need only
to connect the switch to a power source to start using the device. There is no requirement
for additional configurations.
If you are using the power connector supplied by Vantron:
R
ed wire: PWR
B
lack wire: GND

S105 Industrial Switch | User Manual 16 www.vantrontech.com
2.3 I/Os
2.3.1 Power connector
The S105 implements a 3-pin power terminal (3.81mm) that accepts 12V-48V DC input with
over-current protection and reverse polarity protection to ensure reliable operation of the
device in a long term. However, for stable operation with the PSE feature, the device
requires 48V-53.2V power input.
Pinout description:
Pin Signal Description
1 GND Grounding
2 PWR Power supply
3 E-GND Enclosure grounding
2.3.2 Relay
The S105 offers a relay connector that can be used to connect an alarm to notify the user
when the device connected to a specific Ethernet jack is disconnected.
The relay is designed to be used in combination with the DIP switch to monitor the
connectivity of a specific Ethernet jack. The relay contacts are normally open. However, if a
device connected to an Ethernet jack of the switch is disconnected, the contacts will close,
completing the circuit and allowing electricity to flow through the relay. This triggers the
alarm or other notification device that is connected to the relay connector, alerting the user
to the disconnection.
Pin 1

Vantron | Embedded in your success, Embedded in your better life
World-leading provider of embedded/IoT products and solutions
S105 Industrial Switch | User Manual 17 www.vantrontech.com
2.3.3 DIP switch
The DIP switch is designed to be used in combination with the relay connector to monitor
the devices connected to the Ethernet jacks. To monitor an Ethernet jack, place the
corresponding switch to the ON position (up).
Switch 1 is for monitoring the connectivity of all the Ethernet jacks. If it is ON, the relay
contacts will close when any of the connected devices is disconnected. The remaining
switches (2-6) are for monitoring the specific Ethernet jack with the number marked on the
enclosure (1-5).
2.3.4 Grounding screw
With the grounding screw, users can properly ground the switch using a grounding wire to
protect the switch and other network devices from electrical hazards.
2.3.5 Ethernet jacks
The switch offers five RJ45 Ethernet jacks, supporting 10/100M Base-T data rate. Ethernet
jacks 1-4 offers an option for the PSE feature while Ethernet jack 5 offers an option for the
PD feature. These Ethernet jacks can be controlled by DIP switches 2-6, respectively and
DIP switch 1 controls all the jacks.
