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.

2-7. Ports
The JetNet 3212G-2C2F supports IEEE 802.3 10Base-T, IEEE 802.3u 100Base-T,
IEEE 802.3ab 1000Base-T also support IEEE 802.3z for Gigabit Fiber. This
section will introduce how to wiring, install the Ethernet Cable for RJ-45 connector
and Gigabit SFP transceiver.
Gigabit TX ( RJ-45 connector)
All of RJ-45 ports will auto detect 10Base-T and 100Base-TX or 1000Base-T
connections. Auto MDI/MDIX allows users to connect another switch or
workstation without changing straight through or crossover cabling. See Figure A,
B, C and D for the schematic diagram of straight through and crossover cabling.

The RJ-45 ports of JetNet 3212G-2C2F supports auto-MDI/MDI-X function
without any cable change when you use an Ethernet cable to connect other
devices, such as computers, switches or hubs.
Gigabit SFP port
The SFP port supports hot swappable function and user can change SFP fiber
transceiver without system power off. This feature is useful for field site install if the
fiber signal cannot attach the other end device, just change the different SFP
transceiver type which with large power launch power budget.
Korenix provides various type of SFP transceivers for your application. Please
refer the order information.

3. Mounting Installation
3-1. DIN-Rail Mounting
The DIN-Rail clip is already attached on the rear side of JetNet 3212G-2C2F.
JetNet 3212G-2C2F supports EN 50022 standard DIN Rail, in the following
diagram includes the dimension of EN 55022 DIN Rail for your reference
The DIN rail should behind the
spring when install the JetNet
3212G-2C2F onto the standard
DIN Rail.
Follow the steps below to mount
the JetNet 3212G-2C2F to the
DIN-Rail track
1.Insert the upper end of the
DIN-Rail clip into the back of
the DIN-Rail track from its
upper side
2.Lightly push the bottom of the
DIN-Rail clip into the track.
3.Check if the DIN-Rail clip is
tightly attached to the track.
1.To remove the JetNet 3212G-2C2F from the track, reverse the steps above.

11
4. System Installation
4-1. Installation and Testing
1. Take out your JetNet 3212G-2C2F Industrial Gigabit Ethernet switch from the
package box.
2. Check if the DIN-Rail clips attached to the JetNet 3212G-2C2F product . If the
DIN-Rail clip is not attached to the product , refer to DIN-Rail Mounting
section for DIN-Rail installation.
3. To place the JetNet 3212G-2C2F product on the DIN-Rail track or wall, refer to
the Mounting Installation section.
4. Pull the terminal blocks off the JetNet 3212G-2C2F product and wire the power
lines. Refer to 2-4 the Wiring the DC Power Inputs section for how to wire the
power inputs.
5. PWR1 and PWR2 dual power inputs can be connected to power sources
simultaneously. When the primary power source fails (the default setting is
PWR1), the system will automatically switch to the secondary power source
(PWR2), preventing any power interruption.
Both of Power 1 and Power 2 support positive electricity power system.
6. Check the LEDs of PWR1 and PWR2 to make sure that JetNet 3212G-2C2F
series product is operating normally.
7. Use Category 5e or Category 6 straight through Ethernet cables with RJ-45
connectors to connect network devices.
8. Connect one side of an Ethernet cable with a RJ-45 connector to the JetNet
3212G-2C2F product’s Ethernet port (RJ-45 port), and the other side of the
Ethernet cable to the network device’s Gigabit Ethernet port.
9. If you want to connect with Gigabit Fiber, please install appropriate SFP fiber
transceiver and fiber cable. To ensure the connection is working, please notice

12
the type of fiber transceiver of JetNet 3212G-2C2F and the other end of device.
10.Check the LED indicator of port status (blinking green) on the JetNet
3212G-2C2F product to see if the network connection is successfully
established.11.
11.Power on the PC host, activate the Command Line mode, and ping the
connected Ethernet device to see if it responds.
11.1 To enable the “Command Line mode”, click Run in the Start menu, type
Command, and click OK to continue.
11.2 Type ping 192.168.1.1 command to check the connection. Here we use IP
address 192.168.1.1 as an example. Before the testing, be sure your PC
host and target device are in the same subnet.

13
12.Repeat step 10 to make sure that the connection of each device connected to
the JetNet 3212G-2C2F product is successfully established.
13.Power on the host, activate the Command Line mode, and ping the connected
Ethernet device by typing “ping –t 192.168.1.1”command to see if it will
respond.
14.The parameter-”t”allow you to continue to ping the network device, as shown
in the figure below.
Before you continue, make sure that both PWR1 and PWR2 are successfully
connected to power sources. When PWR1 fails, the LED for PWR1 will go out. At
that moment, if the ping command is still replying, then it proves that redundant
power input function works normally.
15.Exit the Command Line mode, and connect PWR1 power input. At this stage,
your JetNet 3212G-2C2F product has been tested and the installation is
completed.

5. Troubles shooting
Make sure you are using the correct DC power supplier (DC10~60V for
JetNet 3212G-2C2F).
Select Ethernet cables with specifications suitable for your applications to set
up your systems. Ethernet cables are categorized into unshielded twisted-pair
(UTP) and shielded twisted-pair (STP) cables. Category 3, 4, 5 Ethernet
cables are suitable for systems with 10 Mbps transmission speed. For
systems with 100/1000 Mbps transmission speed, Category 5 Ethernet cables
are the only suitable specifications for this environment. Also make sure that

15
the distance between each node cannot be longer than 100 meters (328 feet).
If the power LEDs goes off as the power cord plugged in, a power failure
might occur. Check the power output connection to see if there is any error at
the power source. If you still cannot solve the problem, contact your local
dealer for assistance
