Overview
Introduction
The 8-port M12 IP40 unmanaged industrial switch is a rugged device to
be deployed in various environments. The Ethernet switch conforms to
EN50155, EN50121-3-2, EN50121-4 railway applications standards.
Heavy Duty
Designed with circular M12 connectors and constructed with metallic
housing, the Ethernet switch provides the rugged Fast Ethernet
interface to withstand vibration and shock.
Dual Power Inputs
The redundant power input design for the Ethernet switch gives a
backup power solution. With both the power inputs supplied, if either
one fails the other one will be activated to keep the system operating
continually.
Flexible Mounting
The Ethernet switch is compact and can be mounted on the wall, and it
is suitable for any space-constrained environment.
Bypass Function
The equipment is designed with the function known as Bypass. When
the power failure occurs, a shorted circuit between two Ethernet ports
(P1 and P2) is formed to have the equipment being a bypassed device
to prevent the network from disconnecting.

LED Indicators
LED indicators located on the front panel display the status of system power,
networking and power feeding over Ethernet of the Ethernet switch. Please refer to the
following table for further details.
LED Color Description
PWR1 Green On Power input 1 is active
Off Power input 1 is inactive
PWR2 Green On Power input 2 is active
Off Power input 2 is inactive
LNK/ACT Green
On Connected to network
Blinks Data is transmitting/receiving
Off Not connected to network

Fast Ethernet Ports
Prepare the M12, 4-pole D-Coded Fast Ethernet Port mating cable for Ethernet
connection. The M-12 D-coded Fast Ethernet ports are auto-sensing for 10Base-T or
100Base-TX devices connections. Auto MDI/MDIX means that you can connect to
another switch or workstation without changing straight through or crossover cabling.

Installation
Wall Mounting
To hang the Ethernet switch on the wall, please follow the steps below.
1. Prepare the two wall-mount plates and six screws included.
2. Align the screw holes between the wall-mount plates and the unit as the figure
illustrated.
3. Secure the plates to the unit with the accompanying screws.
4. Having secured the plates to the unit, you can hang the Ethernet switch on something
like nails sticking out from the wall.

12
DIN-Rail Mounting
To mount the Ethernet switch to a standard DIN rail, please follow the steps below.
1. Prepare the DIN-rail clip and three screws included.
2. Align the screw holes between the clip and the unit as the figure illustrated.
3. Secure the DIN-rail clip to the unit with the accompanying screws.
4. After you have secured the DIN-rail clip to the unit, position the clip side of the
Ethernet switch directly in front of a standard DIN rail. Make sure the top of the clip
hooks over the top of the DIN rail.

13
Grounding the Ethernet Switch
Follow the instructions below to attach the Ethernet switch to ground.
When installing the Ethernet switch, the ground connection must
always be made first and disconnected last.
1. Locate and remove the dome screw which has a ground symbol beside it.
2. Attach the ground wire to the screw hole with the dome screw.
ATTENTION

Troubleshooting
Verify that you are using the correct power cord/adapter. Don’t use the power adapter
with DC output higher than the rated voltage of the equipment. Or the equipment will be
damaged.
Select proper cables to construct your network. Please check that you are using the right
cables.
Diagnosing LED Indicators:the equipment can be easily monitored through panel
indicators, which describes common problems you may encounter and where you can
find possible solutions to assist in identifying problems.
If the power indicator does not light up when the power cord is plugged in, you may have
a problem with power cord. Then check for loose power connections, power losses or
surges at power outlet. If you still cannot resolve the problem, contact your local dealer
for assistance.
If the LED indicators are normal while the corresponding cables are connected correctly
but the networking is still inactive, please check your system’s Ethernet devices’
configuration or status.
