Introduction
The Industrial Gigabit Switch is designed for harsh
environments where it is exposed to moisture, temperature
fluctuations and vibration. With a temperature range of -40°C
to 85°C, the Industrial Gigabit Ethernet Switch can be used
under the most adverse conditions. The PoE ports with
IEEE802.3af/at support can supply PoE capable devices with
up to 30 W per port. It ensures a constant availability in
highly sensitive areas such as transport, production, traffic
and safety monitoring. The simple plug and play system
allows the Industrial Gigabit Switch to be quickly integrated
into the respective environment. With its Gigabit
connectivity, the Industrial Gigabit Switch is a flexible, costeffective solution for the industrial environment.

Upper Panel
The upper panel has a standard 6-Pin industrial power input
terminal for double redundant power backup and accepts DC
power input.
Power input
This unit provides a 6-pin terminal block. It can be operated
using 48-57 V DC power source. Always make sure your input
voltage is within this supported voltage range.
To connect power:
This unit supports two power inputs. Follow the printed
polarity for +P1-, +P2- and ground. Connect positive wires to
V+, connect negative wires to V-, and connect a neutral wire
to the ground mark.
+P1- is for power input one connection (PWR1).
+P2- is for power input two connection (PWR2).

WARNING:
Always SHUT OFF power source to connect power wire.
WARNING:
Any exceeded input voltage will not make this unit function
and may damage this unit.
Grounding column
The switch already comes with lightning protection
mechanism. You can also ground the switch through
the PE (Protecting Earth) with Ground Cable.

Installation of the Switch
This part describes how to install your Ethernet Switch and
make connections to it. Please follow the following
instructions to avoid incorrect installation causing device
damage and security threat.
Before cleaning the switch, unplug the power plug of the
switch first. Do not clean the switch with wet cloth or
liquid;
Do not place the switch near water or any damp area.
Prevent water or moisture from entering the switch
chassis;
Do not place the switch on an unstable case or desk. The
switch might be damaged severely in case of a fall;
Ensure proper ventilation of the equipment room and
keep the ventilation vents of the switch free of
obstruction;
Make sure that the operating voltage is the same one
labeled on the switch;
Do not open the chassis while the switch is operating or
when electrical hazards are present to avoid electrical
shocks
