1. Introduction
This document describes the method of how to use the Korenix JetNet
3212G-2C2F Industrial 12-port Ethernet switch, includes installation the
specifications that it has. Following this user manual, you can get fully
imagination about JetNet 3212G-2C2F switch and all information to help
you construct the network infrastructure. The following are brief introduction
of JetNet 3212G-2C2F switch.
Industrial Gigabit Ethernet Switch
The JetNet 3212G-2C2F is a 12 port industrial Gigabit Ethernet switch
designed with enhanced design specification, including wider operating
temperature and power input range to best fit in heavy industrial field
applications. It also equipped a rugged metal case with thirty grade ingress
protection to against damaged solid objects or dust; With the excellent
characteristics of heat dissipation, JetNet 3212G-2C2F has better survive
ability than ordinary Gigabit Ethernet switch which is enclosure by steel
metal with various of heat dissipation holes.
Flexible Optical adopt ability
As the trend of fiber interface, JetNet 3212G-2C2F combines four
hot-swappable sockets for Small Form-factor Pluggable (SFP) fiber
transceiver. To adopt different type of fiber optical cable or enlarge fiber
network campus, the JetNet 3212G-2C2F just need replace new fiber
transceiver to meet the specification of optical fiber cable and achieve best
inventory performance.
Fault Alarm
The JetNet 3212G-2C2F provides an alarm relay to trigger out a real alarm
signal for power event. The alarm mechanism can be trigger an external
alarm equipment to inform maintenance I.T. engineers. It makes a result of
maintenance time saving.

2-3. Bottom View
The bottom side of the JetNet 3212G-2C2F includes two 4-pin removable
terminal block connectors
The power range of JetNet 3212G-2C2F is from DC 10~60V with
redundancy and polarity reverse function.
To prevent interference and get better performance, it is strongly
suggest make a well earth grounding by the “Earth Ground Screw”.

2-4. Wiring the DC Power Inputs
Follow the steps below to wire JetNet 3212G-2C2F redundant DC power
inputs.
1. Insert the positive and negative wires into the V+ and V- contacts respectively
of the terminal block connector
2. Tighten the wire-clamp screws to prevent the DC wires from being loosened.
3. The Power 1 and Power 2 support power redundancy and polarity reverse
protection functions.
