Connecting to the Network
Connect one end of the Ethernet cable to NPort 5110’s 10/100M Ethernet port and the other end of
the cable to the Ethernet network. NPort 5110 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.

network.
! The Ethernet LED will flash when Ethernet packets are being transmitted or received.
