2. Installation
2.1 Unpacking
The product package contains:
The device unit for Din-rail mounting
QR code label linking to product documentation cloud
2.2 Safety Cautions
To reduce the risk of bodily injury, electrical shock, fire and damage to the product, observe the following
precautions.
Do not service any product except as explained in your system documentation.
Opening or removing covers may expose you to electrical shock.
Only a trained service technician should service components inside these compartments.
If any of the following conditions occur, unplug the product from the electrical outlet and replace the
part or contact your trained service provider:
-The power cable, extension cable, or plug is damaged.
-An object has fallen into the product.
-The product has been exposed to water.
-The product has been dropped or damaged.
-The product does not operate correctly when you follow the operating instructions.
Do not push any objects into the openings of your system. Doing so can cause fire or electric shock by
shorting out interior components.
Operate the product only from the type of external power source indicated on the electrical ratings
label. If you are not sure of the type of power source required, consult your service provider or local
power company.
Since the surface temperature of the device may be higher than 70℃in range of
the rated operating temperatures, install and operate the product only by authorized
personnel only. Install the product at a restricted area where un-authorized persons
cannot reach.

2.3 DIN-Rail Mounting
171BIn the product package, a DIN-rail bracket is provided for mounting the switch in an industrial DIN-rail
enclosure.
172BThe steps to mount the switch onto a DIN rail are:
1. 1287BInstall the mounting bracket onto the switch unit as shown below:
2. 1288BAttach bracket to the lower edge of the DIN rail and push the unit upward a little bit until the bracket can
clamp on the upper edge of the DIN rail.
3. 1289BClamp the unit to the DIN rail and make sure it is mounted securely.

2.7 Reset Button
The reset button is used to perform a reset to the device. It is not used in normal cases and can be used for
diagnostic purpose. If any network hanging problem is suspected, it is useful to push the button to reset the
device without turning off the power. Check whether the network is recovered.
The button can also be used to restore the software configuration settings to factory default values.
The operations are:
Operation Function
Press the button and release during operation Reset & boot up the device. The behavior is
same as power boot procedure.
Press the button when boot-up until all LEDs blink. Boot & restore all factory default settings
