About the Apple Ethernet CS II Card
The Apple Ethernet CS II Card expands the
communication capabilities of models of Macintosh
computers that have a communication slot II (CS II).
The card is designed for networks that conform to the
IEEE 802.3 standard for Ethernet.
What’s in the box
m One Apple Ethernet CS II Card with either a
twisted-pair connector, a thin coaxial connector
(with T-connector attached), or an AAUI connector
Note: Keep the card inside its antistatic bag in
the protective cardboard box until you’re ready
to install it.
There are three configurations of the Apple Ethernet
CS II Card, each with a connector for a different type
of Ethernet cable. These are
m twisted pair
m thin coaxial (“coax”)
m One floppy disk containing Ethernet CS II
software
m Warranty card
m AAUI (universal connector)
m User’s guide
This manual provides instructions for all three
configurations of the card.
IMPORTANT If you purchased a new Macintosh and
this booklet came in the box, your Apple Ethernet
CS II Card and software may already be installed,
and no disk containing the Ethernet CS II software
is included. Skip ahead to “Installing Your
Ethernet Software” for information about setting
up your software.
You begin by installing the card and then connecting
it to your network. You should also install the latest
version of the Ethernet software if a disk is included
with the card.
The Apple Ethernet CS II Card requires System
7.5.3 or a later version. For best performance your
system should have 8 megabytes (MB) minimum of
random-access memory (RAM).

IMPORTANT If you’re installing the Apple Ethernet
CS II Thin Coax Card, a T-connector is connected to
your card. Before you install the card, twist the
T-connector to unlock it from your card and set
it aside.
5. Align the card over the communications slot and
press down firmly and evenly on both ends until the
card fits snugly into place.
You can test to see if the card is properly
connected by lifting the card slightly. If it resists
and stays in place, it’s connected.
4. Tilt the card to fit the connector through the back
panel’s opening and hook the small metal bracket at
the top of the card to the edge of the opening.
6. Follow the directions that came with your computer to
replace the back panel or lid and reattach any cables
you removed earlier.
This procedure depends on the model you have.

Troubleshooting
Following are guidelines for handling common
problems. If these suggestions don’t help you fix the
problem, contact your network administrator.
If the AppleTalk or TCP/IP control panel icon is missing:
The AppleTalk or TCP/IP control panel may have
been moved from the Control Panels folder. Look
for it on your hard disk, drag it to the Control Panels
folder, and restart your Macintosh.
Also check to see whether your software is set to use
Open Transport networking. See the instructions in
“Setting the Network Software Selector.”
IMPORTANT The first step in troubleshooting any
problem with your network connection is to check
each of the following items.
m The computer’s power is on.
m The card is installed correctly.
m The Ethernet cable’s connector is securely
fastened to your card.
m The network cable is in good condition and
locked to the connector.
Your Ethernet software may not have been installed
properly. If you can’t find the AppleTalk or TCP/IP
control panel, you’ll need to reinstall the network
software according to the instructions in this guide.
m If your card is configured for a thin coax cable
and your computer is on either end of the
network, be sure that a terminator is locked to the
T-connector.
m Your Ethernet network is working properly—no
one else is having problems with the network.
If Ethernet doesn’t appear in the AppleTalk or TCP/IP
control panel:
Make sure that you have installed your Apple
Ethernet CS II card in your communications slot II.
Also, there may have been a problem with the
network software installation. Reinstall your
network software according to the instructions in
this guide.
15
If you can’t select Ethernet in the AppleTalk or TCP/IP
control panel:
If you don’t see network services listed in the Chooser:
Make sure your network connection is set correctly.
Open the AppleTalk control panel and choose
Ethernet. (If the Chooser is open, close and reopen it
to update its information.)
You can only select Ethernet when the network
cable is installed properly and the network is
operating correctly. Be sure that the network cable is
properly attached. If you are still unable to select
Ethernet, there may have been a problem with the
network software installation. Reinstall your
network software according to the instructions in
this booklet.
On the Apple Ethernet CSII Twisted Pair Card, the
external LED will light when a proper network
connection is established. If the LED doesn’t
light,the network is not responding to the card. See
your network administrator.
On the Apple Ethernet CS II Twisted Pair Card, the
external LED will light when a proper network
connection is established. If the LED doesn’t light,
the network is not responding to your card. See you
network administrator for help.
If you can access some services but can’t access a
particular service (printing, for example), the device
providing that service might be located in a different
AppleTalk zone, or it might be malfunctioning,
switched off, or disconnected from the network.
There may also be a break somewhere in the
network cables between your Macintosh and the
missing service.
16
If your system can’t load Ethernet at startup and
reverts to LocalTalk:
If your card is defective or you have a problem with the
installation and your network administrator cannot help:
Your System file may be damaged or your Ethernet
installation was unsuccessful. Try reinstalling the
network software. Also check that your network
cable is properly attached and terminated, if

necessary. Check that your card is properly installed.
If the system won’t let you change the
network connection:
You may be using essential services (such as file
sharing) or applications that might prohibit the
change. Quit the service named in the system’s alert
message and try changing the network connection
again. You can also try quitting all application
programs. If this doesn’t work, and it’s all right for
you to disrupt services, shut down your Macintosh
using the Shut Down command. Restart the
computer, change the network connection, and start
the service or application again.
