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.

The 3Com EtherDisk XL version 3.01 diskettes provided by Dell are compatible with
the 3C905 family of NICs. If you purchased a 3Com 3C905-based NIC separately, do
not attempt to use the 3Com EtherDisk XL diskettes that came with the NIC. Use
only the 3Com EtherDisk XL version 3.01 diskettes that were provided by Dell.
