4-1. Wiring the DC Power Inputs
Follow the steps below to wire JetNet 3008’s / JetNet 3008f’s dual DC
power inputs.
[Note] The suitable electric wire ranges is from 12 to 24 AWG.
Equipment intended for installation in a Restricted Access Location.
Before install power, be sure the power supply module is compliance with
UL certificated LPS power and the power system is shut down to avoid
any damage. About the wiring please refer following diagram.

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.

4-2. Wiring the Alarm Relay
JetNet 3008 /JetNet 3008f provides one dry relay output for power or port
link event; the alarm relay is “Normal open”and form a close circuit when
The relay conductor ability is 12W when it connects with a DC 24V power
source and maximum current is 0.5A. In the following diagram shows how
to make an alarm circuit.
Maximum 0.5A current / DC24V

4-3. Wiring Earth Grounding
In the real fields, there might have a lot of automatic device, such as AC
motors, electric welding machine, power generator; those devices will
generate electromagnetic and disturb communications. To prevent those
noises, the switch should be well earthed. In the figure-shows how to
make connection.
4-4. Enabled the Event Alarm Function
This session introduces how to configure and enable the event alarm to
alert maintenance engineer once system event occurred. Both of JetNet
3008 and JetNet 3008f equipped with one dry relay output for port link fails
or power fails. The feature is controlled by digital control circuits and effect
immediately without system reset when DIP SWITCH changed.
On the bottom side of JetNet 3008 and JetNet 3008f, there is one 9-Pin
DIP SWITCH for alarm control. By inserting the port and power wiring,
setting the DIP SWITCH of the intended Alarm to “ON”, the relay output
will form a short circuit if alarm occurred.

4-5. Cabling
The UTP cable connection between the JetNet 3008 and the attached
devices (switches, hubs, workstations, etc.) must be less than 100 meters
(328 ft.) long.
The transmission distance of JetNet 3008f is depends on the type of fiber
transceiver model and the attenuation of optical fiber cable. The following
information is fiber transceiver specification of JetNet 3008f series. Please
ensure the cable attenuation between two far end nodes is less than the
power budget of fiber transceiver. Table-3 shows the specification of
optical fiber transceiver JetNet 3008f used.

4-6. System Power-On and Testing
1. Take your JetNet 3008 / JetNet 3008f Industrial 8-port Fast Ethernet
Switch out from the box.
2. To place the JetNet 3008 on the DIN-Rail track, refer to the Mounting
Installation section.
3. Pull the terminal block off the JetNet 3008 and wire the power lines.
Refer to the Wiring the DC Power Inputs section for how to wire the
power inputs.
4. 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.
5. Check the LEDs for PWR1 and PWR2 to make sure that your JetNet
3008 is operating normally.
6. Use Category-5 or above straight through Ethernet cables with RJ-45
connectors to connect network devices.

7. Connect one side of an Ethernet cable with a RJ-45 connector to the
JetNet 3008’s Ethernet port (RJ-45 port), and the other side of the
Ethernet cable to target device that equipped IP address and can
handle ICMP protocol, like as ping packet.
8. Check the port status LED indicator (blinking green) on the JetNet3008
to see if the network connection is established successfully.
9. Power on your host PC, make an Ethernet connection to JetNet 3008
and check the connected port is link up ;The connection diagram
shown as below:
10.To enable the “Command Line mode”, click on Run in the Start menu,
type Command, and click on OK to continue.
Type ping 192.168.1.1 command to check the connection. Here we use IP
[Note] Make sure that the connected network switches support MDI/MDI-X function. If they
do not support this function, use a crossover Ethernet cable.

17
address 192.168.1.1 as an example.
11.Repeat step 10 to make sure that the connection of each device
connected to the JetNet3008 is successfully established.
12.Power on the PC host, activate the Command Line mode, and ping the
connected Ethernet device by typing “ping 192.168.1.1 –t”command
to see if it will respond. Do remember the PC host IP address is same
subnet address as target device –192.168.1.1.
13.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
