NPort S8000 Series Introduction
1-2
Overview
The NPort S8000 is an industrial device server that integrates a managed Ethernet switch with a fully functional
serial device server. The NPort S8000 device servers are designed to make your industrial serial devices
instantly Internet-ready.
The NPort S8000 offers 2 fiber Ethernet ports, 3 Ethernet ports, and 4 RS-232/422/485 serial ports in a single
device. This not only saves cabinet space and reduces power consumption, but also saves money since you
don’t need to purchase separate switches and serial device servers.
The compact size of the NPort S8000 device servers makes them the ideal choice for connecting
RS-232/422/485 serial devices—such as PLCs, meters, and sensors—to an IP-based Ethernet LAN, making it
possible for your software to access serial devices anywhere over a LAN or the Internet.
The NPort S8000 is a fully equipped managed Ethernet Switch with a suite of useful maintenance and
monitoring functions, and is designed to provide smooth and reliable operation in harsh industrial
environments. It is ideal for keeping automation systems running continuously, sending status reports to help
prevent system damage and losses, and managing your industrial Ethernet networks and serial devices.
Industrial Communications and Automation
As the world’s networking and information technology becomes more complex, Ethernet has become the major
communications interface in many industrial communications and automation applications. In fact, a whole
new industry has sprung up to provide Ethernet products that comply with the requirements of demanding
industrial applications.
Industrial vs. Commercial
Users have found that when transplanting Ethernet from comfortable office environments to harsh and less
predictable industrial environments, commercial Ethernet equipment available in today’s market simply cannot
meet the high reliability requirements demanded by industrial applications. This means that more robust
networking equipment, commonly referred to as industrial Ethernet equipment, is required for these
applications.
Informative vs. Passive
Since industrial Ethernet devices are often located at the endpoints of a system, such devices cannot always
know what’s happening elsewhere on the network. This means that industrial Ethernet communication
equipment that connects these devices must provide system administrators with real-time alarm messages.

NPort S8000 Series Getting Started

Wiring Requirements
ATTENTION
Safety Fi
rst!
Be sure to disconnect the power cord before installing and/or wiring your NPort S8000.
Wiring Caution!
Calculate the maximum possible current in each power wire and common wire. Observe all electrical codes
dictating the maximum current allowable for
each wire size.
If the current goes above the maximum ratings, the wiring could overheat, causing serious damage to your
equipment.
Temperature Caution!
Please take care when handling
the NPort S8000. When plugged in, the NPort S8000’s internal components
generate heat, and consequently the casing may feel hot to the touch.
You should heed the following:
•Use separate paths to route wiring for power and devices. If power wiring and device wiring paths must
cross, make sure the wires are perpendicular at the intersection point.
NOTE: Do not run signal or communication wiring and power wiring in the same wire conduit. To avoid
interference, wires with different signal characteristics should be routed separately.
•You can use the type of signal transmitted through a wire to determine which wires should be kept separate.
The rule of thumb is that wiring that shares similar electrical characteristics can be bundled together.
•Keep input wiring and output wiring separate.
•Where necessary, it is strongly advised that you label wiring to all devices in the system.
Connecting the Power
Connect the 12-48 VDC power line with the NPort S8000’s terminal block. If the power is properly supplied, the
“Ready” LED will show a solid red color until the system is ready, at which time the “Ready” LED will change to
a green color.
Take the following steps to wire the redundant power inputs:
1. Insert the negative/positive DC wires into the V-/V+ terminals.
2. To keep the DC wires from pulling loose, use a small flat-blade screwdriver to tighten the wire-clamp
screws on the front of the terminal block connector.
3.
Insert the plastic terminal block connector prongs into the terminal block receptor, which is located on the
S8000’s top panel.

NPort S8000 Series Getting Started
2-5
Connecting to the Network
Connect one end of the Ethernet cable to the NPort S8000’s 10/100M Ethernet port and the other end of the
cable to the Ethernet network. If the cable is properly connected, the NPort S8000 will indicate a valid
connection to the Ethernet in the following ways:
•The Ethernet LED maintains a solid green color when connected to a 100 Mbps Ethernet network.
•The Ethernet LED will flash when Ethernet packets are being transmitted or received.
Connecting to a Serial Device
Connect the serial data cable between the NPort S8000 and the serial device.
LED Indicators
The LED indicators of NPort S8000 series are described in the following table.
Type Color Meaning
PWR 1 Green Power 1 input
PWR 2 Green Power 2 input
LINK (FX) Green FX port 100 Mbps is active
Blinking Data is being transmitted/received at 100 Mbps
LINK Green 100 Mbps Ethernet connection
Blinking 10 Mbps Ethernet connection
Master Green When the NPort is the Master of this Turbo Ring
Yellow When the NPort is the Ring Master of this Turbo Ring and the Turbo
Ring is broken
Coupler Green When the NPort enables the coupling function to form a backup path
Serial Port TX Green The serial port is transmitting data.
Serial Port RX
Yellow
The serial port is receiving data.
Ready Red Steady On: Power is on and NPort is booting up.
Blinking: Indicates an LAN IP conflict, or DHCP or BOOTP server did
not respond properly.
Green Steady On: Power is on and NPort is functioning normally.
Blinking: The device server has been located by Administrator’s
Location function.
Off Power is off, or power error condition exists.
Adjustable Pull High/low Resistors and Terminators for the
RS-485 Port
In some critical environments, you may need to add termination resistors to prevent the reflection of serial
signals. When using termination resistors, it is important to set the pull high/low resistors correctly so that the
electrical signal is not corrupted. Since there is no resistor value that works for every environment, DIP
switches are used to set the pull high/low resistor values for each RS-485 port.
To set the pull high/low resistors to 150 KΩ, make sure both of the assigned DIP switches are in the OFF
position. This is the default setting.
To set the pull high/low resistors to 1 KΩ, make sure both of the assigned DIP switches are in the ON
position.

ATTENTION
Do
not set the resistors to 1 KΩ. When using RS-232. Doing so will degrade the RS-232 signals
and reduce the
effecti
ve communication distance.
Wiring the Relay Contact
The NPort 8455I-MM-SChas two sets of relay output—relay 1 and relay 2. Each relay contact consists of two
contacts of the terminal block on the NPort 8455I-MM-SC’s top panel. Refer to the next section for detailed
instructions on how to connect the wires to the terminal block connector, and how to attach the terminal block
connector to the terminal block receptor. The meaning of the two contacts used to connect the relay contacts
is illustrated below.
The fault circuit will open if
1. A relay warning event is triggered,
OR
2. The S8000 is the Master of this Turbo Ring,
and the Turbo Ring
is broken,
OR
3. Start-up failure.
If none of these three conditions
is met, the fault circuit will
remain
closed.
Wiring the Digital Inputs
The NPort 8455I-MM-SC unit has two sets of digital inputs, DI 1 and DI 2. Each DI consists of two contacts of
the 6-pin terminal block connector on the NPort 8455I-MM-SC’s top panel. The remaining contacts are used for
the NPort 8455I-MM-SC’s two DC inputs. Top and front views of one of the terminal block connectors are shown
below.

Take the following steps to wire the digital inputs:
1. Insert the negative (ground)/positive DI wires into the ┴/I1
terminals.
2. To keep the DI wires from pulling loose, use a small flat-
blade
screwdriver to tighten the wire-
clamp screws on the front of the
terminal block connector.
3. Insert the plastic terminal block connector prongs into the
terminal block receptor, which is located on the NPort
8455I-MM-SC’s top panel.

NPort S8000 Series Initial IP Address Configuration
3-2
Static and Dynamic IP Addresses
Determine whether your NPort S8000 needs to use a static IP or dynamic IP address (either DHCP or BOOTP
application).
•If your NPort S8000 is used in a static IP environment, you will assign a specific IP address using one
of the tools described in this chapter.
•If your NPort S8000 is used in a dynamic IP environment, the IP address will be assigned
automatically from over the network. In this case, set the IP configuration mode to DHCP, BOOTP.
ATTENTION
Consult your network administrator on how to reserve a fixed IP address for your NPort S8000 in the MAC
-
IP
mapping table when using a DHCP server or BOOTP server. For most applications, you should assign a fixed IP
address to your NPort S8000.
Factory Default IP Address
The NPort S8000 is configured with the following default private IP address:
192.168.127.254
Note that IP addresses that begin with “192.168” are referred to as private IP addresses. Devices configured
with a private IP address are not directly accessible from a public network. For example, you would not be able
to ping a device with a private IP address from an outside Internet connection. If your application requires
sending data over a public network, such as the Internet, your NPort S8000 will need a valid public IP address,
which can be leased from a local ISP.
Configuration Options
Web Console
You may configure your NPort S8000 using a standard web browser. Please refer to chapter 5 and chapter 6,
for details on how to access and use the NPort S8000 web console.
ARP
You may use the ARP (Address Resolution Protocol) command to set up an IP address for your NPort S8000.
The ARP command tells your computer to associate the NPort S8000’s MAC address with an IP address.
Afterwards, use Telnet to access the NPort S8000 and its IP address will be reconfigured.
ATTENTION
In order to use
the ARP setup method, both your computer and the NPort S8000 must be connected to the
same LAN.
Alternatively, you may use a cross-over Ethernet cable to connect the NPort S8000
directly to your
computer’s Ethernet card.
Before executing the ARP command, your NPort S8000 must be configured w
ith the
factory
default IP address (192.168.127.254) and your computer and the NPort S8000
must be on the same
subnet.
To use ARP to configure the IP address, complete the following:
1. Obtain a valid IP address for your NPort S8000 from your network administrator.
2. Obtain your NPort S8000’s MAC address from the label on the bottom panel.

3. Execute the arp -s command from your computer’s MS-DOS prompt as follows:
arp -s <IP address> <MAC address>
For example,
C:\>arp -s 192.168.200.100 00-90-E8-04-00-11
4. Next, execute a special Telnet command by entering the following exactly:
telnet 192.168.200.100 6000
When you enter this command, a Connect failed message will appear, as shown below.
5. After the NPort S8000 reboots, its IP address will assigned to the new address and you can reconnect using
Telnet to verify that the update was successful.
Telnet Console
Depending on how your computer and network are configured, you may find it convenient to use network
access to set up your NPort S8000’s IP address. This can be done using Telnet.
1. From the Windows desktop, select Start Run, and type the following in the Run window:
Telnet 192.168.127.254
If your IP address is different from the default setting, use your IP address instead. Click OK.
