Your computer’s NIC connector (an RJ45 connector located on the back panel) is
designed for attaching an unshielded twisted pair (UTP) Ethernet cable. Press one end
of the UTP cable into the NIC connector until the cable snaps securely into place.
Connect the other end of the cable to an RJ45 jack wall plate or to an RJ45 port on a
UTP concentrator or hub, depending on your network configuration. Observe the fol-
lowing cabling restrictions for 10BASE-T and 100BASE-TX networks.
