D-Link DFE-550TX Ethernet Adapter

Introduction
Thank you for choosing the D-Link DFE-550TX - the value leader among Fast Ethernet adapters for the
PCI-Bus. This introduction gives a general description of the newer networking technologies found on the
DFE-550TX.
ACPI Power Management
The DFE-550TX adapter complies with the Advanced Configuration and Power Interface 1.0 (ACPI)
specifications. ACPI is a new open industry specification providing power management support systems
through hardware and operating system cooperation. The DFE-550TX can reduce power consumption by
entering Sleep mode along with the host computer. Although in Sleep mode, the network interface card
(NIC) will continue to monitor the LAN looking for wake-up packets.
Wake On LAN
Wake On LAN (WOL) is an ACPI function allowing a powered down (sleeping) computer to be powered ON
from a remote station. To use the WOL feature, the NIC must be WOL capable and the motherboard of the
PC must be ACPI compliant.
While powered-down computers Sleep, WOL enabled NICs monitor LAN traffic for valid Wake-up frames.
When one is received, the NIC will immediately wake-up and send a signal to the motherboard to power ON
the computer.
Some uses for the WOL feature include:
•Forgot a document and out of town? Send a Wake-up signal to your computer and retrieve the needed
file.
•Initiate long routines and reports before you get to work.
•Transfer files when the network traffic is low (during late hours).
•Power ON your PC before you arrive to work.
•The MIS department can upgrade software on computers after hours from a remote station.
WOL is very helpful in limiting the power consumption of PCs, workstations, and kiosks.
Flow Control
The DFE-550TX implements IEEE 802.3x compliant flow control for full duplex, which provides traffic
management functions for full-duplex operation. Flow control allows for enhanced full duplex operation with
switches. When operating at full duplex (requiring a direct connection to a switch) and the switch’s data
buffer is about to overflow, a Pause frame will be transmitted to the DFE-550TX. The ensuing idle time
keeps the buffer from overflowing and prevents data from being lost. This enhancement can improve
network throughput, avoid collisions and prevent lost data, helping the network achieve optimal
performance.
IP Multicasting
The DFE-550TX uses chip-level address filtering when implementing IP Multicasting (defined in RFC
1112). This hardware-based implementation provides a huge performance increase over other interface
cards. Formerly, broadcast packets were used for multicasting, but they are a less than ideal solution for
transmitting packets to groups. This is because broadcast packets reach every terminal on the network,
creating undue traffic and occupying CPU time on all computers.
IP Multicasting is a much better way to send data to groups, especially since routers and even switches can
filter packets so they only reach those stations that are part of the group. The DFE-550TX goes one step
further by examining multicast packets on the card itself (rather than using the computer’s CPU) and only
accepting those packets for the group(s) in which the host belongs, thus conserving CPU utilization.
This can be very useful since more and more multicast data, such as corporate messages to employees, stock
quotes, video and audio conferencing, and database replication is transmitted on today’s networks.

IP Multicasting can eliminate an organization's need to maintain parallel networks for voice, video and
data.
DMI/Desktop Management Interface
DMI is an Operating System/Network Operating System-independent management framework that allows
system vendors to support multiple market/customer segments with a single management strategy. DMI
lowers the Total Cost of Ownership (TCO) by providing a common framework for managing desktop
systems, mobile systems and servers.
DMI supports a management schema (Management Information Format [MIF]), allowing manageable
components to be described within various platforms in a standard descriptive language. MIFs are
extensible, allowing the DFE-550TX to export value-added management capabilities. These value-added
management features enable remote troubleshooting and higher quality management of computer
resources.
IEEE802.1p Priority Tagging
With the growing number of network applications, local area networks (LANs) must deliver data for a wide
variety applications. Email, file transfers, database queries, voice over IP (VoIP), video-conferencing and
multimedia must all be delivered to the end-user’s. Some of the traffic, such as video-conferencing, is of a
higher priority, with a slight delay of packets resulting in noticeable degeneration of video and audio
quality, while other traffic, such as email will not be noticeably affected by tiny delays. The large number of
programs run over today’s networks serves to impede the ability to deliver time-critical data. Even if
bandwidth is not usually a problem on your network, during peak hours bursts in network traffic can result
in the delay of time-critical traffic.
IEEE802.1p defines seven levels of prioritization for Ethernet packets. High priority packets will be sent
through a network using 801.2p-compliant switches first. Lower priority packets will be transferred
whenever bandwidth is available. When properly setup, this ensures that time-critical data arrives on time
and is not affected by other traffic.
IEEE802.1Q VLANs
The IEEE802.1Q VLAN can help improve network performance and security by segmenting the network
into VLANs. IEEE802.1Q VLANs can limit broadcast and node-to-node (unicast) traffic to a single VLAN.
This limits the effects of broadcast storms and provides additional security for your network.
To set up GVRP VLANs, which support dynamic registration, the adapter should be connected to a switch
with GVRP VLAN capability.
For VLANs to function, the computer in which this NIC is installed must be using Windows 95 or later as
its operating system.

Traffic Management Statistics
The DFE-550TX incorporates sixteen packet counters that can be used by network management
applications. This is far greater than the three mandatory counters implemented by most other network
interface cards. The large number of counters on the DFE-550TX allows network management applications
to provide accurate and detailed statistics on a wide range of network attributes. The packet counters
included are:
1. FramesTransmittedOK
2. BroadcastFramesTransmittedOK
3. MulticastFramesTransmittedOK
4. OctetsTransmittedOK

D-Link DFE-550TX Ethernet Adapter
Installation
Installation of the DFE-550TX 10/100 NWay Ethernet Adapter requires installing the hardware first. Once
the interface card has been installed into the host computer, the software can be installed.
Unpacking
CAUTION:Under ordinary circumstances, a DFE-550TX interface card will not be affected by static
electricity. However, it is good practice to eliminate static charges by touching a sizable metal
object before handling the adapter card.
Open the shipping carton and carefully remove all items. In addition to this User's Guide, ascertain that
you have:
•One DFE-550TX Ethernet Adapter Card.
•DFE-550TX Software CD-ROM.
•WOL Cable.
Installing the Adapter
1. Shut down the computer, unplug its power cord, and remove the cover.
2. If your order does not include the Boot ROM option, go ahead to Step 3. If your order includes the Boot
ROM option, then install the Boot ROM Chip by plugging the chip into the Boot ROM Socket on the
DFE-550TX card. The notched end of the Boot ROM Chip must be aligned with the notched end of the
Boot ROM Socket. Opposite alignment will destroy the Boot ROM Chip!
3. Firmly insert the contact edge of the DFE-550TX card into any available PCI Bus expansion slot.
4. Install the bracket screw to secure the card to the computer chassis.
5. At this point, refer to section Connecting the WOL Cable to install the WOL Cable between the NIC and
the PC motherboard.
6. Replace the computer cover.
7. Reconnect the computer power cord, and switch the computer power on. If the BIOS section of your
computer boot program is Plug and Play compliant, then at power-up the BIOS will automatically
configure itself for the newly installed DFE-550TX adapter.
NOTE: Due to a fault in some Plug-n-Play BIOS programs, it happens occasionally that a newly installed
adapter is assigned an IRQ Number which is already assigned to another device. In such a case, the
conflicting IRQ Numbers (IRQ numbers must be unique) will cause faults in the behavior of both
devices. If this happens, it is necessary to run the CMOS Setup utility, and manually assign a non-
conflicting Interrupt Number to the DFE-550TX.
Connecting the WOL Cable
The WOL Cable†is an interconnect cable with standard 3-pin connectors on each end. Please
follow the procedures listed below to ensure proper installation of the WOL cable.
1. Connect either end connector of the WOL Cable to the NIC WOL Connector. Both ends of the
WOL Cable are identical, so either end may be used.
2. Examine the PC motherboard and/or refer to the manual for the motherboard to locate the
corresponding WOL Connector on the motherboard. The actual location is system dependent,
but the motherboard may have a label beside the WOL Connector. After you have located the
†The WOL Cable is an optional component of your DFE-550TX kit. If a cable is not included in your kit, purchase the cable through your
local computer retailer.

D-Link DFE-550TX Ethernet Adapter
Installation 5
WOL connector on the motherboard, connect the cable.
3. Power-ON the PC and press <Delete> or <F1> when prompted to enter the PCI/ISA BIOS
CMOS Setup. Enable the WOL function or the power-ON function of the PC. The name of
this function is system dependent, but may be located in a category heading titled something
like Power Management. Refer to your computer’s manual for more information regarding the
CMOS Setup Utility and BIOS settings.
NOTE: If your system’s motherboard WOL Connector does not fit the WOL Cable or does not have 3 pins, do
not attempt to force a connection or alter the components to fit. Doing so could permanently damage
your computer.
Connecting the Network Cable
Category 5 UTP cable qualifies for both 100BASE-TX Fast Ethernet and 10BASE-T Ethernet cabling rules.
The maximum length of any single cable segment is 100 meters. Please keep in mind, however, that the
maximum cable run between any two stations in a collision domain is 205m.
Connecting for 100Mbps Fast Ethernet
Category 5 UTP cable is required for Fast Ethernet operation. The maximum cable run between the DFE-
550TX and the supporting hub or switch is 100m. The cable must be straight-through (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 jack of the DFE-550TX, and the other end into a normal (non-Uplink) port on the supporting
device.
Connecting for 10Mbps Ethernet
Category 3, Category 4, and Category 5 UTP cable, as well as EIA/TIA-568 100-ohm STP cable all meet
Ethernet cabling requirements. The maximum cable run between the DFE-550TX and the supporting hub
or switch is 100 meters. The cable must be straight-through (not a crossover cable) with an RJ-45 connector
at each end. Make the network connection by plugging one end of the cable into the RJ-45 jack of the DFE-
550TX, and the other end into a normal (non-Uplink) port on the supporting device.
Note: The DFE-550TX will use NWay to automatically detect whether it is connected at 10Mbps or
100Mbps and configure itself accordingly. The duplex mode will likewise be auto-negotiated by NWay at the
same time, allowing the host computer to be up and running on the network as soon as possible with a
minimum of trouble.
Software Installation
On account of the great variety of network environments in which the DFE-550TX may be used, the
instructions for software installation are given as README files on the DFE-550TX Software CD-ROM.
Review the root directory and locate the subdirectory containing the appropriate software for use with your
network operating system. Access the README file for overview information. For full installation details,
see the README file and the referenced instruction files in the sub-directory.

D-Link DFE-550TX Ethernet Adapter
Verification/Diagnostic Program
This test program verifies configuration of the DFE-550TX as set by the installation procedure, and assists
with isolation of any faults in operation. Verification and testing procedures are optional, and will only be
useful in the unusual event that there is a fault, such as an interrupt number conflict among your computer
expansion cards. If your installation provides normal operation, you might choose to skip these procedures.
The Verification/Diagnostic Program provides two levels of testing: adapter function testing and network
operation testing. Adapter testing includes a variety of diagnostic procedures.
Adapter testing does not require substitution of a loopback cable. All procedures of the Adapter test may be
carried out with the network cable connection in place.
For the network operation test, the cable connecting your station with its supporting hub must be in place.
Network testing involves the broadcast transmission of test packets from the primary station. The test
cannot be fully implemented unless a second station on the LAN is available to the network operation test,
in order to return the test packets to the primary station.
To run the Verification/Diagnostic Program, proceed with these steps:
Adapter Function Test
1. Insert the DFE-550TX Software CD-ROM in an available drive (here shown as drive A). At the DOS
prompt (here shown as >), key in: > A:\DIAG.EXE
and <RETURN>. The opening screen of the Verification/ Diagnostic program will appear.
NOTE: Read the README.TXT, on the CD-ROM, to choose the appropriate diagnostic program
for your operating system.
2. Review the reported configuration data before proceeding to Step 3.
3. The Configuration Data screen also features a Diagnostic Menu. Follow the cues at the foot of the
screen to select and run the Adapter Basic Diagnostic program. The adapter function test results will
appear onscreen. In the Loopback test, test signals are intercepted and reflected at the MAC level
without reaching the network cable. If the results are normal, then go ahead to the Network Operation
test, starting with Step 4.

D-Link DFE-550TX Ethernet Adapter
Installation 7
Network Operation Test
4. If you have access to a second station on the LAN, then skip ahead to Step 5. If you do not have access
to a second station on the LAN, then the network test will be limited to blind transmission of test
packets (none of which will be returned to the primary station). Follow the cues at the foot of the screen
to select and run the Network Diagnostic program. Observe the Packets Sent line to see a steadily and
rapidly increasing packet count. This will indicate normal transmission onto the LAN, and will be the
end of your Verification/Diagnostic run. Skip the remaining steps shown below.
5. Remove the DFE-550TX Software CD-ROM from your station's (the primary station's) CD-ROM drive,
and insert it into an available drive of a second station on your LAN. At the DOS prompt (here shown
as >), key in: > A:\DIAG.EXE
and <RETURN>. The opening screen of the Diagnostic program will appear onscreen at the second
station. Follow the cues at the foot of the screen to select and run the Network Test program at the
second station. The second station then begins broadcasting test packets, and at the same time is also
ready to receive and return test signals transmitted from the primary station newly installed DFE-
550TX.
6. Return to the primary station and follow the cues at the foot of the screen to select and run the Network
Diagnostic program. Observe the Packets Sent and Packets Received lines to see that they track
together (always showing equal count numbers), which verifies normal network operation.
The most likely causes of failure for any of the diagnostic tests are incorrect options settings, option
settings that conflict with the settings of other boards or improper installation. In the event of any
failure in diagnostic tests, refer to the Troubleshooting section of this guide.

D-Link DFE-550TX Ethernet Adapter
Troubleshooting
If you experience any problems with the adapter, first verify that the appropriate driver is loaded, that the
proper grade of cable is employed for the network connection, and that the supporting hub is functioning
properly.
1. Ascertain that the adapter card is fully and firmly seated in the slot connector.
2. Check the length and rating of connecting cables.
3. Ascertain that the adapter PCI slot is not deactivated at the BIOS level. The CMOS Setup utility in PCI computers
ordinarily provides the option to activate or deactivate PCI slots.
4. Replace the adapter in question with a verified adapter and run NIC (software) diagnostic tests.
5. Install the questioned adapter in another PCI computer and run the tests again.
6. Remove all other PCI adapters from the computer and run the tests again. If the verification/diagnostic run is then
normal, then there is probably an interrupt number conflict which will have to be resolved manually by a CMOS
Setup utility run after you have reinstalled all of the expansion cards.
The DFE-550TX Adapter features three LED indicators to assist in network diagnostics:
•LINK/ACT Indicator
A steady green LED indicates that the card is receiving power and there is a good link between the DFE-550TX and
the device it is connected to. The LED will flash when the adapter is sending or receiving data.
•100M Indicator
This LED shows steady green (ON) when operating at 100Mbps. It is dark (OFF) when connected at 10Mbps.
•FULL (duplex) Indicator
This LED is ON for full duplex connections and OFF when connected at half duplex.
