Grounding NPort 5400
Grounding and wire routing helps limit the effects of noise due to electromagnetic interference (EMI).
Run the ground connection from the ground screw to the grounding surface prior to connecting
devices.
This product is intended to be mounted to a well-grounded mounting surface such as a metal panel.
SG: The Shielded Ground (sometimes called Protected Ground)
contact is the left most contact of the 3-pin power terminal block
connector when viewed from the angle shown here. Connect the
SG wire to an appropriate grounded metal surface.
Connecting to the Network
Connect one end of the Ethernet cable to NPort 5400’s 10/100M Ethernet port and the other end of the
cable to the Ethernet network. If the cable is properly connected, NPort 5400 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 maintains a solid yellow color when connected to a 10 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 NPort 5400 and the serial device.
