Introduction

Thank you for choosing D-Link DFE-660TX, the value leader
among Ethernet / Fast Ethernet adapters for CardBus notebook PCs.
This chapter provides a general description of DFE-660TX features,
with a summary of features at the end of the chapter. Installation
instructions are given in Chapters 2 and 3.

General Description

The D-Link DFE-660TX 10/100 Ethernet PC Card for CardBus
notebook PCs is a credit-card sized Ethernet / Fast-Ethernet adapter
for connecting a notebook PC to an IEEE 802.3 or 802.3u Ethernet
network. The notebook PC must be equipped with CardBus (32 bit)
extension bus and Type II or Type III PC Card slot (s).

NOTE:

The terms "PC Card" and “CardBus” are used throughout

this manual to refer to those objects as defined in the
PCMCIA / PC Card standards published by Personal
Computer Memory Card Industry Association (PCMCIA).
The term “slot” is used in this manual is synonymous with
“socket” where the standards use the latter term in
reference to the physical receptacles of a host notebook
computer, for insertion/connection of PC Cards. More
information on the standards is available from PCMCIA’s
www server at http://www.pc-card.com.

The DFE-660TX automatically detects the parameters of its Ethernet
environment, and automatically negotiates and determines its own
speed and duplex settings as required for maximum performance in

Introduction

its environment. (The autonegotiation function is effective only
when the DFE-660TX is connected to the network by a device
(switch or hub) which also has autonegotiation functionality.)

Inside its compact case, the D-Link DFE-660TX holds an Ethernet
controller, network processing interface, a 68-pin PC Card Standard
front-end plug which connects to the notebook PC, and a 15-pin
back-end receptacle for connecting the media coupler. The
DFE-660TX requires no pre-installation setup -- simply insert its
front end into the notebook PC's PC-Card slot.

The DFE-660TX is supplied with a media coupler which plugs into
the back end (15-pin receptacle) of the DFE-660TX. The other end
of the media coupler has an RJ-45 receptacle which receives the
network cable. The media coupler features LED indicators for
linkage and activity states, and for the speed and duplex settings.

About Fast Ethernet

Fast Ethernet is a network technology specified by IEEE Standard

802.3u. It extends the traditional 10Mbps (10 megabit/sec) Ethernet
technology to achieve 100Mbps (100 megabit/sec) transmission and
reception. Because Fast Ethernet retains the traditional Ethernet
CSMA/CD (Carrier Sense, Multiple Access, Collision Detect)
protocol, it remains wholly compatib le with 10Mbps Ethernet while
providing a tenfold increase in network capacity.

The Fast Ethernet standard specifies three subtypes, corresponding
to three media types:

100Base-TX (using two twisted pairs in EIA 568 Category 5
UTP or STP cable)

100Base-T4 (using four twisted pairs in a Category 3,
Category 4, or Category 5 UTP cable)

DFE-660TX Fast Et hernet PC Card User's Guide

Introduction

100Base-FX (using two fiber-optic strands).

The DFE-660TX provides half-duplex 100Base-TX operation (in
Category 5 twisted-pair cable environments). It does not provide
100Base-T4 or 100Base-FX operation. To provide for traditional
10Mbps Ethernet operation in twisted-pair cable environments, the
DFE-660TX also offers 10Mbps Ethernet operation, in full-duplex
and half-duplex modes. The DFE-660TX's autonegotiation
capability provides for automatic selection of the best operation
mode.

About Autonegotiation

The basic idea of autonegotiation can be understood by reflecting for
a moment on the familiar process of making a dialup connection
between two modems. You have probably heard some
gravelly−sounding exchanges between your local modem and a
modem at the other end of a telephone line. (These exchanges are
ordinarily played out through a speaker in your local modem). As
irritating as those few seconds of noise may be, they do let you know
that your modem and the remote modem are on the job, preparing
for your intended communication with the remote computer.

The preparatory work of the two modems during those few seconds
before you see the “ connect” message is to

negotiate

the best data
communication scheme which is supported by both modems, and
which is suitable for the quality of the telephone-line connection
between them. The parameters to be settled between the two
modems include best baud rate, compression method, and error
correction method. When the two modems have tested the phone­line quality and have switched to the combination of parameters
which will provide the best data communication, then you are given
the “connect” message which signals the end of the inter-modem
negotiation and the beginning of your intended communication with
the remote computer.

Introduction

Autonegotiation between devices within an Ethernet LAN is similar
in concept, but much briefer. The two devices involved in the
autonegotiation will be your DFE-660TX and the switch or hub
through which it is connected into the LAN. (Switches ordinarily
provide for autonegotiation; traditional hubs do not.) The
parameters to be negotiated between the DFE-660TX and its
supporting switch or hub include speed (100Mbps = Fast Ethernet,
or 10Mbps = traditional Ethernet) and duplex mode (half-duplex or
full-duplex).

Startup communication between the two devices occurs when both
devices are operating, the cable connection between them is good,
and the connected notebook PC's network software is loaded. As
soon as those conditions are satisfied, the preparatory process of
autonegotiation between the DFE-660TX and its supporting device
begins and proceeds automatically.

If the supporting switch or hub has autonegotiation functionality,
then it and the DFE-660TX exchange a series of messages in which
each device signals its capabilities and listens for corresponding
information about the other. The autonegotiation process requires
only a few milliseconds, and the two devices select the best
communication parameters supported by both devices.

If the supporting device does not have autonegotiation functionality,
then its monotone (single capability) message will be recognized by
the DFE-660TX’s autonegotiation facility, and the DFE-660TX will
simply switch to the on e of its own capabilities which match es that
of the supporting device.

Once the autonegotiation is completed, then the line is ready, and it
will provide an optimal data channel between the DFE-660TX and
the supporting device. The line will remain ready without further
autonegotiation action until the linkage is broken. Autonegotiation
then reoccurs at any time that the linkage is restored, again making
the line ready for optimal data communications.

Hardware Installation

In the event that any item is missing, or if you find any mismatch or
damage, promptly contact your dealer for correction.

Hardware Installation

Follow these four steps to install the DFE-660TX:

Step 1 Insert the DFE-660TX

Under the PC Card standard and the corresponding Japanese JEIDA
standard, PC Cards may safely be "hot swapped" –– it is not
necessary to switch the computer's power off before installing or
removing the DFE-660TX, or any other PC Card.

Find/select an open Type II or Type III PC Card slot on your
notebook computer's side or rear panel. Hold the DFE-660TX with
the colorful D-Link splash label u pward . Notice th at the splash label
features a yellow triangle or "arrow," which points to the front end
of the PC Card. Insert the front end of the PC Card into the CardBus
slot, and slide the PC Card all the way into the slot until it reaches a
firm stop.

It is most usual for the lower one of the two slots in the stack
to be designated Slot 1, but there are exceptions. In the
subsequent procedure for DFE-660TX software installation,
it might be useful for you to know whether your DFE-660TX
is installed in Slot 1 or Slot 2. Under Windows 95, you can
check by opening the Control Panel / PC Card display.
Under DOS it is also possible to make a software check, but
it is more difficult. If it develops that you need to make a
trial-and-error determination or correction, then it is easy to
do: just reinstall the DFE-660TX in another slot.

Step 2 Attach the Media Coupler

The back-end receptacle of the DFE-660TX remains accessible
(approximately flush with the case of the computer) when the
DFE-660TX is properly seated in its PC Card slot. Taking care to
keep the top side of the media coupler plug up, insert the plug into
the DFE-660TX's receptacle until it is firmly seated and latched.
(The top side of the plug is labeled with a triangle molded into the
plastic.)

Keep the triangle mark on
top when you plug the media
coupler into the DFE-660TX

NOTE:

When the media coupler plug is firmly seated, it is held in

place by small latching hooks at either side of the plug. To
avoid damage when detaching the plug from the
DFE-660TX, it is necessary to depress the latch wings of

the plug. See the following section, " Remove the
DFE-660TX."

Step 3 Connect to the Network Medium

Make the network connection by running a UTP cable from the
supporting switch or hub to your media coupler. Simply plug one
end (RJ-45 plug) of the cable into an available port of the switch or
hub, and plug the other end (RJ-45 plug) into the RJ-45 socket of
your media coupler.

engaged (and latched) in the back-end receptacle of the DFE-660TX,
the media adapter has a good cable connection to the supporting hub,
and the supporting hub is power on and functioning properly, then
the media coupler’s Ln/Act LED glows steady green ("Linkage"
state).

If the Ln/Act LED remains dark without apparent cause, then the
most likely fault is poor engagement of the 68-pin front-end plug.
Review the following section titled "Remove the DFE-660TX," then
remove the DFE-660TX from its slot. Repeat the procedures of the
above Step 1, "Insert the DFE-660TX," taking care to ensure that the
DFE-660TX is right side up and front-end first, and that it seats
firmly in a suitable PC Card slot of your notebook. Repeat the
procedures of Steps 2 and 3 as necessary get the Ln/Act LED
confirmation.

NOTE:

You might need to wait a few seconds following notebook
powerup, or following insertion of a PC Card, for the
software processing to be completed. The Ln/Act indicator
will remain dark until the software processing is completed.

Remove the DFE-660TX

Follow these two steps to remove the DFE-660TX from its slot:

Step 1 Disconnect the Media Coupler Plug from the DFE-660TX

Unplug the media coupler from the DFE-660TX be fore ejecting the
DFE-660TX fr o m t h e P C C a rd sl o t. T he m ed ia coupler plug is held
in place by small latching hooks at either side of the plug. To
remove the media coupler plug from the DFE-660TX, i t i s n ecessary
to unlatch the hooks by depressing the two small latch wings of the
plug. Use thumb and forefinger to squeeze the latch wings into the
plug body and gently pull the plug out of its receptacle.

your fingers and withdraw it from the PC Card slot.

Connect the Networ k Cabl e

Category 5 UTP cable is good enough to qualify under both the Fast
Ethernet cabling rules and the traditional Ethernet cabling rules. The
maximum individual cable run between any station and its
supporting hub or switch is 100m. The maximum individual cable
run joining two hubs is 10m in general, but is 100m when both hubs
qualify as Ethernet Class 2 Repeaters (

all

D-Link Ethernet hubs do
qualify). But these cable runs may need to be shorter than the given
individual maximum lengths, because their lengths are also restricted
by the rule that the maximum

aggregated

cable run between any two

stations is 205m.

Connecting for Fast Ethernet

Category 5 UTP cable is required for Fast Ethernet operation. The
maximum length of cable between the DFE-660TX and the
supporting hub is 300 ft. The cable must be “straight” (not a
“crossover” cable), with an RJ-45 plug at each end. Make the
network connection by plugging one end of the cable into the RJ-45
receptacle of the media coupler, and the other end into a port of the
supporting hub.

Connecting for 10Mbps Ethernet

Category 3, Category 4, and Category 5 UTP cable, as well as
EIA/TIA - 568 100-ohm STP cable, all qualify under traditional
Ethernet cabling rules. The maximum cable run between the
DFE-660TX and the supporting hub is 300 ft. The cable must be
“ straight” (not a “ crossover” cable) with RJ-45 plug at each end.

Software Installation

Hardware installation as described in Chapter 2 must be completed
before you proceed with software installation.

Instructions for software installation are given as README files on
the D-Link DFE-660TX Software Diskette. The diskette also holds
the Installation Director program, which helps you access the
installation instructions appropriate to your station OS and the
network environment.

Run Installation Director

For proper function of Installation Director, it is necessary that the
DFE-660TX be plugged into a PC Card slot of the notebook PC.
Ascertain that the DFE-660TX is in place, according to Step 1 of
Hardware Installation, above, then insert the D-Link DFE-660TX
Software Diskette into the diskette drive of the notebook PC. Then
select that drive as the active drive. In th e Run dialog box, or at the
command prompt, type the letter designator for that drive (here
assumed to be A), and com p lete the line as follows:

A:\install.exe

Then key

<Enter>

to run Installation Director. It will gu ide you
to, and display, the ap propriate installation instructio ns. Installation
Director provides installation instructions for every combination of
platform OS and network environment in which the DFE-660TX can
be used.

DFE-660TX Fast Et hernet PC Card User's Guide

Software Installation

During your Installation Director run, if you choose DOS as your
station OS, then in some cases Installation Director will provide
additional services. In such cases, you will be prompted to select a
target directory for storage of software modules that Installation
Director will copy over from the D-Link DFE-660TX Software
Diskette. The README text will provide full information on the
additional services provided..

Installation Director also provides access to the Diagnostic Program,
which may be used to check the hardware components of the
DFE-660TX, as well as its proper interoperation with your network.

Installing 16-bit NetWare Client for DOS

If your notebook PC is running MS-DOS or an equivalent OS, then
you will need to install the traditional 16-bit NetWare Client for
DOS

.

Installation Director includes a Quick Install option for the
DFE-660TX support software required for interoperation with the
16-bit NetWare Client for DOS. The screen text, status line guide
text, and helptext of Installation Director will assist you through the
Quick Install procedure.

Troubleshooting

Troubleshooting the

Hardware

Installation

If you experience any problems with the hardware installation, first
ascertain that all network cable connections are firm, that the proper
grade of cable is used for the network connection, and that the cable
makeup is correct (straight –– without un-needed crossovers in the
connector wiring). Check that the supporting hub is power-on and
operating normally, and that the hub is properly qualified (under
10Base-T and/or 100Base-TX standards).

Troubleshooting the Software Installation

You Get the

"DFE -660TX P C C ard No t Detected"

Error

You are running Installation Director, and in the Main Menu you
have selected

Quick Install 16-bit Driver for Dos Netware Client

The Quick Install run is then interrupted by an error message which
says that the

DFE-660TX

PC Card is not detected by the system.

You have followed the instruction given by the error message, to
repeat Step 1 of the Hardware Installation procedure given at the
beginning of Chapter 2 of the User's Guide. And you have then re­run Installation Director. And the same error message has come up.

DFE-660TX Fast Et hernet PC Card User's Guide

Troubleshooting

Proceed as follows:

1. Exit Installation Director. Examine the CONFIG.SYS file in
the root directory of your notebook PC's startup drive (hard
drive). Ascertain that CONFIG.SYS contains a DEVICE
statement for Extended Memory Manager (EMM). Such a
statement should resemble the following example,

DEVICE = C:\DOS\EMM386.EXE X=D000-D7FF

2. If there is no similar DEVICE statement in your notebook PC's
CONFIG.SYS file, then edit the CONFIG.SYS file, adding a
statement copied exactly from the above example.

3. If there such a statement in CONFIG.SYS but the "DFE-660TX
PC Card not detected" error appears on each attempted Quick
Install run anyway, then edit that statement to read exactly the
same as the above example.

4. If, after you have completed the above instructions, the
"DFE-660TX PC Card not detected" error still appears on each
subsequent restart of the notebook PC, then please contact your
dealer or your nearest D-Link office, as listed at the end of this
User's Guide.

You need to "unload the conflicting network driver"

You are running Installation Director, and in the Main Menu you
have selected

Quick Install 16-bit Driver for Dos Netware Client.

Then you have seen the warning message which advises that the
presence in memory of another network card driver could cause a
system halt. (That warning messages appears in every Quick Install
run –– it does not indicate that there is another network card driver
already loaded into memory.) Then you have elected to continue the
Quick Install run. And the Quick Install run has indeed produced a
halt (system hangup).

If you have not been through all of those steps, then you should not
be reading this. You should be in Chapter 3, Software Installation.
And you should be staying on track with your Quick Install run.

only if

your Quick Install run is actually
obstructed by a system halt (so that you can only restore your control
of the notebook PC by a restart). And

only if

after your restart
(which provides assurance of a "clean" DOS environment) you have
tried Quick Install once more (and experienced the system halt once
more). Only then should you conclude that you must "unload the
conflicting network driver."

Stay Cool and Get Help

The first thing you need to know is that "unload the conflicting
network driver" is easier said than done. If you have easy access to a
network administrator (or other resident expert), now might be a
good time to go for help. If you do not have ready access to an
expert, then help may be available from the dealer who has supplied
your DFE-660TX, and you can also get help by calling D-Link
Technical Support at the D-Link office nearest to you (see the list of
office locations at the end of this User's Guide).

"Unload" Really Means "Avoid Loading at Startup"

It is true that driver programs and related software modules, such as
those supplied on your D-Link DFE-660TX Software Diskette, are
often written so that the addition of a "/u" switch or "-u" option to
the command line for load ing the driver will cause unloading of the
same driver (if it is in fact already loaded). But such unloading is
only possible under special circumstances. So, as a practical matter,
what we really must do is

avoid loading of the conflicting driver

upon startup of the notebook PC.
A software installation procedure (such as "Quick Install 16-bit

Driver for DOS NetWare Client") copies the necessary drivers and
related modules from the supplied DFE-660TX Software Diskette,
into the target directory of the notebook PC's hard drive or other

storage. The installation program also adds commands to the
computer's AUTOEXEC.BAT file, so that each time the computer is
subsequently booted up (and you then make certain choices in the
startup menus, if any), the drivers and related modules are
automatically loaded into m emory.

The "conflicting driver" problem now at hand arises because certain
commands already present in your notebook PC's AUTOEXEC.BAT
file are being executed during bootup, and are causing some kind of
previously installed network driver module to be loaded into
memory. The presence of that network driver in memory is now
making it impossible to load the DFE-660TX network driver
software (16-bit driver for DOS NetWare client).

So the fix is to delete from AUTOEXEC.BAT the line which is
causing the conflicting driver to be loaded. Thus we will

avoid

loading of the conflicting driver

when we next restart the notebook
PC. And the trick is to delete that line from AUTOEXEC.BAT
without deleting or changing anything which needs to remain
unchanged in AUTOEXEC.BAT (so that your notebook PC will
behave as you expect it to after each startup).
