The JetNet 2205 séries supports IEEE 802.3 10Base-T, IEEE 802.3u 100Base-T.
This section will introduce how to wire, install the Ethernet Cable for RJ-45
connector.
FE TX ( RJ-45 connector)
All of RJ-45 ports will auto detect 10Base-T and 100Base-TX connections. Auto
MDI/MDIX allows users to connect another switch or workstation without changing
straight through or crossover cabling. See Figure A, B for the schematic diagram
of straight through and crossover cabling.

The RJ-45 ports of JetNet 2205 series 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.

3. Mounting Installation
3-1. DIN-Rail Mounting
The DIN-Rail clip is already attached on the rear side of JetNet 2205 series. JetNet
2205 series 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
2205 series onto the standard
DIN Rail.
Follow the steps below to mount
the JetNet 2205 series 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.
4.To remove the JetNet 2205
series from the track, reverse
the steps above.

4. System Installation
4-1. Installation and Testing
1. Take out your JetNet 2205 series Industrial Ethernet switch from the package
box.
2. Check if the DIN-Rail clip is attached to the JetNet 2205 series 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 2205 series product on the DIN-Rail track or wall, refer to
the Mounting Installation section.
4. Pull the terminal blocks off the JetNet 2205 series 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. Use Category 5e or Category 6 straight through Ethernet cables with RJ-45
connectors to connect network devices.
6. Connect one side of an Ethernet cable with a RJ-45 connector to the JetNet
2205 series product’s Ethernet port (RJ-45 port), and the other side of the
Ethernet cable to the network device’s Ethernet port.
7. If you want to connect with Fiber, please install appropriate fiber SC wire with
SC terminal into the SC connector of the switch. The transmission distance of
JetNet 2205f is depends on the type of fiber transceiver model and the
attenuation of optical fiber cable.
8. Check the LED indicator of port status (blinking green/Amber) on the JetNet
2205 series product to see if the network connection is successfully
established.11.
9. Power on the PC host, activate the Command Line mode, and ping the

13
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.
10.Repeat step 10 to make sure that the connection of each device connected to
the JetNet 2205 series product is successfully established.
11.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

14
respond.
12.The parameter-”t”allow you to continue to ping the network device, as shown
in the figure below.
13.Exit the Command Line mode and connect PWR1 power input. At this stage,
your JetNet 2205 series product has been tested and the installation is
completed.

5. Troubles shooting
◼Make sure you are using the correct DC power supplier (DC12~40V)
◼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 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
