Where to install the card
Some kinds of Ethernet cards fit into the computer’s communication slot;
however, so do internal modem cards. If you install an internal modem card
in the communication slot but you also want to connect to an Ethernet
network, purchase an Ethernet card that instead uses the computer’s PCI
(peripheral component interconnect) slot.
m If your Ethernet card uses a PCI slot, follow the instructions in “Installing
a PCI Card” in the section “Installing an Expansion Card” in Appendix B,
and the instructions that came with the card.
m If your Ethernet card uses the communication slot (this type of card is
often referred to as an Apple Ethernet Comm II card), follow the
instructions in “Installing a Communication Card” in the section
“Installing an Expansion Card” in Appendix B, and the instructions that
came with the card.
Network type
Find out what kind of network you will be connecting to (your network
administrator should be able to provide this information). Depending on the
kind of network, you will choose among cards that use one of these types of
cables:
m thin or thick coaxial (or “coax”) cable, also called 10Base-2
m 10Base-T (twisted pair) cable
m fiber-optic media or other standard Ethernet cable
So for example, if you know that your Ethernet network uses 10Base-T cables,
and you want to use your communication slot for a modem card, you would
purchase a 10Base-T Ethernet card that fits in a PCI slot.
WARNING Do not connect cables to the back of your computer when the
power is on or you may damage your system.
