Ports
RJ-45 ports (Auto MDI/MDIX): RNS5 has five 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/MDIX allows users to connect
another switch or workstation without changing straight through or crossover
cabling. See Figure C and C-1 for the schematic diagram of straight through and
crossover cabling.
8
Fig C Straight Through Cabling Schematic
Fig C-1 Cross Over Cabling Schematic
All ports of RNS5/8 support the 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 Table 2.

Mounting Installation
DIN-Rail Mounting
The DIN-Rail clip is already attached to the RNS5/8 when packaged. If the
DIN-Rail clip is not screwed on the RNS5/8, follow the instructions and the figure
below to attach the DIN-Rail clip to the RNS5/8.
Rear Panel of the RNS5/8
DIN-Rail Clip
1. Use the screws to attach the DIN-Rail clip to the rear
panel of the RNS5/8.
2. To remove the DIN-Rail clip, reverse step 1.
10
Follow the steps below to mount the RNS5/8 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 RNS5/8 from the track, reverse the steps above.
11
Wall Mounting
Follow the steps below to install the RNS5/8 with the wall mounting plate.
1. To remove the DIN-Rail clip from the RNS5/8, loosen the screws from the
DIN-Rail clip.
2. Place the wall mounting plate on the rear panel of the RNS5/8.
3. Use the screws to tighten the wall mounting plate onto the RNS5/8.
4. Use the hook holes at the corners of the wall mounting plate to hang the
RNS5/8 onto the wall.
5. To remove the wall mounting plate, reverse the steps above.

Hardware Installation
The following figure illustrates a typical application of RNS5/8 Industrial
5-port/8-port Ethernet Rail Switch.
Installation and Testing
1. Take your RNS5/8 Industrial 5-port/8-port Rail Switch out of the package box.
2. Check if the DIN-Rail clip is attached to the RNS5/8. If the DIN-Rail clip is not
attached to the RNS5/8, refer to DIN-Rail Mounting section for DIN-Rail
installation. If you want to wall-mount the RNS5/8, refer to Wall Mounting
section for wall mounting installation.
3. To place the RNS5/8 on the DIN-Rail track or wall, refer to the Mounting
Installation section.
13
4. Pull the terminal block off the RNS5/8 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.
6. Check the LED for PWR1 and PWR2 to make sure that your RNS5/8 is
operating normally.
[Note] If you are using DC IN power jack to supply power to the
RNS5/8, please check the PWR LED
7. Use Category 5 straight through Ethernet cables with RJ45 connectors to
connect network devices.
8. Connect one side of an Ethernet cable with a RJ45 connector to the RNS5/8’s
Ethernet port (RJ-45 port), and the other side of the Ethernet cable to the
network device’s Ethernet port (RJ-45 port).
9. Check the port status LED indicator (blinking green) on the RNS5/8 to see if
the network connection is successfully established.
14
10.Power on the host, activate the Command Line mode, and ping the connected
Ethernet device to see if it will respond.
10.1 To enable the “Command Line mode”, click on Run in the Start menu,
type Command, and click on OK to continue.
10.2 Type ping 192.168.1.1 command to check the connection. Here we use
IP address 192.168.1.1 as an example.
11.Repeat step 10 to make sure that the connection of each device connected to
the RNS5/8 is successfully established.
15
12.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.
13.The parameter ”t” allows 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 point, you should notice that the ping command is still responding, this verifies
that the redundant power input function is working correctly.
14.Exit the Command Line mode, and connect PWR1 power input. .Your RNS5/8
has been tested and the installation is complete.
16
Trouble shooting
„
„
Make sure you are using the correct VDC power supplies (12 to 48 VDC) or
power adapters. Do not use power adapters with DC output over 48V. It will
damage the device.
Select Ethernet cables with specifications suitable for your applications to set
up your system. 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. You also need to make
sure that the distance between each node is not longer than 100 meters (328
feet).
„
If the power indicator does not turn on when the power cord is plugged in, you
may have a problem with the power cord. Check for loose power connections,
power loss or surges at the power outlet. If you still cannot resolve the
problem, contact your local dealer for assistance.
