Overview
JetNet 4000 Series is a web-managed rail switch that is specially designed for industrial
applications. JetNet 4000 uses one-piece formed aluminum case that complies with IP31
industrial standard, allowing JetNet 4000 to operate under harsh industrial environments. JetNet
4000 provides dual DC power inputs, ensuring your systems to run non-stop. JetNet 4000 also
supports Super Ring technology, which can offer you industrial-grade redundant network
solution. When your primary path fails, the entire system can still function normally with the
secondary path activated. JetNet 4000 supports fiber connectors, effectively extending switches’
transmission distance. Web-based management interface ensures easy management by using
web browser over the network.
Ethernet Switching Technology
Ethernet Switching Technology dramatically boosted the total bandwidth of a net work, eliminated
congestion problems inherent with CSMA/CD (Carrier Sense multiple access with Collision
Detection) protocol, and greatly reduced unnecessary transmissions.
This revolutionized networking. First, by allowing two-way, simultaneous transmissions over the
same port (Full-duplex), which essentially doubled the bandwidth. Second, by reducing the
collision domain to a single switch-port, which eliminated the need for carrier sensing. Third, by
using the store-and-forward technology’s approach of inspecting each packet to intercept corrupt
or redundant data, switching eliminated unnecessary transmission that slow the network. By
employing address learning, which replaced the inefficient receiving port.
Auto-negotiation regulates the speed and duplex of each port, based on the capability of both
devices. Flow-control allows transmission from a 100Mbps node to a 10Mbps node without loss
of data. Auto-negotiation and flow-control may require disablement for some networking
operations involves legacy equipment. Disabling the auto-negotiation is accomplished by fixing
the speed or duplex of a port.
Ethernet Switching Technology supplied higher performance at costs lower than other solutions.
Wider bandwidth, no congestion, and the reduction in traffic is why switching is replacing
expensive routers and inefficient hubs as the ultimate networking solution. Switching brought a
whole new way of thinking to networking.

Wiring the Power Inputs
1. Insert the positive and negative wires into the V+ and V- contact on the terminal block
connector.
2. Tighten the wire-clamp screws to prevent the DC wires from being loosened.
Note: The suitable electric wire ranges from 12 to 24 AWG.
Note: The additional power jack is designed for office use.
Wiring the Relay Output
The relay output alarm contacts are in the middle of the terminal block connector as shown in the
figure below. By inserting the wires and set the DIP switch to “ON”, relay output alarm will detect
any power or port failures, and form an open circuit. The figure below illustrates an example of
how relay output alarm works.
Note: The connection point of alarm relay output only switches on and off the circuit. It does not
supply any power. The connection point can only bear 1A@DC24V.
Fault Alarm Contact

The open circuit will form when the
power failure or port link failure.
The fault alarm device will send a
warning signal to warn the user, ex:
alarm sound or flash light.

1. Insert the alarm device’s negative wire into assigned position of the terminal block connector.
2. Tighten the wire-clamp screws to prevent the wires from being loosened.
Wiring the Ethernet Ports
RJ-45 ports with auto MDI-MDI-X function: JetNet 4008 has eight 10/100 Mbps auto-sensing
ports for 10Base-T or 100Base-TX device connection. The UTP ports will auto-detect 10Base-T
and 100Base-TX connections. Auto MDI/MDI-X function allows users to connect another switch
or workstation without changing straight-through or cross-over cabling. See the figures below for
the schematic diagram of straight-through and cross-over cabling.
Straight-through Cabling Schematic Cross-over Cabling Schematic
Use four twisted-pair Category 5 cables for RJ-45 port connection. Connect one side of an
Ethernet cable into the JetNet’s TX port, while the other side is connected to the attached device.
The LED will light up when the cable is correctly connected. Refer to the LED Indicators section
for descriptions of the function of each LED indicators. The cables between the JetNet and the
attached device (e.g. switch, hub, or workstation) must be less than 100 meters (328 ft.).
All ports of JetNet 4000 support auto-MDI/MDI-X function. When you use an Ethernet cable to
connect other devices, such as computers, switches or hubs, pin 1, 2, 3, and 6 of the 8-pin RJ45
connector are used to communicate with the connected devices. Pin1, 2, 3, and 6’s signals are
converted by the MDI-X function, as shown in the table below.
Pin MDI-X Signals MDI Signals
1 RD+ TD+
2 RD- TD3 TD+ RD+
6 TD- RD-
Two switches are now up-linked together. If we change the up-link port man ually at this time,
MAC address table will change as well. After MAC address table makes the changes, and then
the data can be transmitted between these two switches. This period of time is called MAC
address table aging time. Korenix JetNet 4000’s default aging time is 5 minutes, which means
that if you manually change the up-link port, you will need to wait for 5 minutes before the data
Korenix JetNet 4000 Series Industrial Web-Managed Ethernet Rail Switch User’s Manual

can be sent. If the aging time is too short, MAC address table will constantly refresh, resulting in
large consumption of the switch’s computing resources. For this reason, longer aging time is
recommended.
Wiring the Fiber Ports
To connect the fiber port on your JetNet 4005f or JetNet 4008f to another one located on another
JetNet, follow the figure below. Wrong connection will cause fiber ports not to work normally.
JetNet fiber models have two 100Base-FX ports with SC type connectors.
Fiber segment using single mode must use 9/125 or 10/125 um single-m ode fiber cables. For
single mode, the connection distance can be up to 30 km.
Fiber segment using multi mode must use 50 or 62.5/125 um multi-mode fiber cables. For single
mode, the connection distance can be up to 2 km.
DIN-Rail Mounting Installation
The DIN-Rail clip is already attached to the JetNet 4000 Series products when packaged. If the
DIN-Rail clip is not screwed on the JetNet, follow the instructions and the figure below to attach
the DIN-Rail clip to the JetNet. Here we use JetNet 4008 as an example.
1. Use the screws to attach the DIN-Rail clip to the rear panel of the JetNet 4008.
2. To remove the DIN-Rail clip, reverse step 1.
Follow the steps below to mount the JetNet to the DIN-Rail track.
1. First, 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 on the track.
4. To remove the JetNet from the track, reverse the steps above.
Wall-Mounting Installation
Follow the steps below to install the JetNet 4008f with the wall mounting plate.
1. To remove the DIN-Rail clip from the JetNet 4008f, loosen the screws from the DIN-Rail clip.
2. Place the wall mounting plate on the rear panel of the JetNet 400 8f.
3. Use the screws to tighten the wall mounting plate onto the JetNet 4008f.
4. Use the hook holes at the corners of the wall mounting plate to hang the JetNet 4008f onto
the wall.
5. To remove the wall mounting plate, reverse the steps above.
