2-7. Ethernet interface introduction
The JetNet 3010G equipped 7 ports 10/100 Fast Ethernet, 3 Gigabit SFP / RJ-45
combo ports. The 10/100Mbps Fast Ethernet ports support auto negotiation and
MDI/MDI-X; the Gigabit RJ-45 support 100/1000Mbps for port 8, 9 and port 10 supports
1000Mbps only.
The following table shows the link ability of each Ethernet port.
Port RJ-45 Link Speed SFP
1~7 10Mbps Full/Half Duplex
100Mbps Full/Half Duplex Not Avaliable
8, 9 RJ-45 /SFP combo
10Mbps Full Duplex
100Mbps Full/Half Duplex
1000Mbps Full/Half Duplex
1000Mbps Fiber Transceiver
10 1000Mbps Full/Half Duplex 1000Mbps Fiber Transceiver
Note:The combo port SFP fiber link first function may not work properly, since
the most of SFP fiber transceiver vendors have applied energy saving
technology into the transceiver and can’t trigger fiber link signature to inform
hardware circuit to change the link mode; therefore, it is recommended don’t
make connection for SFP fiber link and RJ-45 link at same time.
2-8. Quality of Service
The JetNet3010G supports IEEE802.1p Tag based Quality of Service (QoS) and based
on the priority ID which is embedded in VLAN Tag. The JetNet 3010G per port provides
4 priority queues for packet service and with 8:4:2:1 (Higher: High: Low: Lower) Weight
Round Robin (W.R.R.) scheduling. The following table indicates the priority ID and
queuing mapping for JetNet3010G.
JetNet 3010G
Priority Queue Priority ID
High Queue 6,7
Middle Queue 4,5
Low Queue 0,3
Lowest Queue 1,2

2-9. Wiring Cable
RJ-45 port: The RJ-45 cable connection between the JetNet3010G and the attached
devices (switches, hubs, workstations, etc.) must be less than 100 meters (328 ft.) long
and follows up IEEE 802.3 standard.
SFP port: The SFP port permits standard SFP fiber transceiver, which is provided by
Korenix with 3.3v DC power supply. The fiber cable of SFP transceiver will depends on
SFP fiber transceiver specification. Please notice that the link connection supports
either one of RJ-45 or SFP. The SFP Link/Activity LED will be on when Gigabit RJ-45
and SFP Transceiver link with device, because the Fiber link connection always with
high priority than RJ-45 port.

4-1 Installation and Testing
1. Take out your JetNet3010G Industrial Gigabit Switch from the package
box.
2. Check if the DIN-Rail clip is attached to the JetNet3010G. If the
DIN-Rail clip is not attached to the JetNet3010G, refer to DIN-Rail
Mounting section for DIN-Rail installation. If you want to wall-mount

the JetNet3010G, refer to Wall Mounting section for wall mounting
installation.
3. To place the JetNet3010G on the DIN-Rail track or wall, refer to the
Mounting Installation section.
4. Pull the terminal block off the JetNet3010G and wire the power lines.
Refer to 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 and negative
electricity power system. Please notice the power system for power 1
and power 2 only accept either positive or negative electricity power
system at one time
6. Check the LEDs of PWR1 and PWR2 to make sure that JetNet3010G
is operating normally. Use Category 5 straight through Ethernet cables
with RJ45 connectors to connect network devices.
7. Connect one side of an Ethernet cable with a RJ45 connector to the
JetNet3010G’s Ethernet port (RJ-45 port), and the other side of the
Ethernet cable to the network device’s Ethernet port (RJ-45 port).
8. 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 the type of fiber transceiver of JetNet3010G’s
and the other end of device.
9. Check the port status LED indicator (blinking green) on the
JetNet3010G to see if the network connection is successfully
established.
10.Power on the PC host, activate the Command Line mode, and ping the
connected Ethernet device to see if it will respond.
11. To enable the “Command Line mode”, click Run in the Start menu, type
Command, and click OK to continue.

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.
12.Repeat step 10 to make sure that the connection of each device
connected to the JetNet3010G 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 JetNet3010G has been tested and the installation is
completed.
The industrial network is now established successfully. Computer A is able
to connect serial to Ethernet Device via JetNet3010G Industrial Gigabit
Switch, providing a reliable network environment. About the test wiring
architecture, please refer to the figures as following:

5. Trouble Shooting
Make sure you are using the correct DC power suppliers (DC12~ 48 V) or
power adapters.
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 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.
