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 K
Ω, 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 K
Ω, make sure both of the assigned DIP switches are in the ON
position.
