Introduction

SMC’s EZ PCI Card 10/100 is a dual-speed Fast Ethernet card for PCI local bus-compliant computers. A true
plug-and-play device, this card is auto-configurable upon power up and also supports auto-negotiation to
automatically select the optimum speed and communication mode of an attached device. This EZ PCI Card
10/100 complies with ACPI and OnNow PC98/ PC99 and also supports Remote LAN Wakeup for remote
management. Software can be loaded and updated, configurations changed, data backed up and inventory
checked, all from a central location. See “Remote LAN Wakeup” on page 5 for more information.

Remote LAN Wakeup

Remote LAN Wakeup capability is a key feature of a centrally managed PC environment. This technology
enables networked PCs to be “woken up” from a sleep or powered-off state so they can be managed from a
central location, at any time of the day or night.

To employ Remote LAN Wakeup, three elements are required:

• Desktop management software that can send a “wake-up” packet to a PC.

• A Wake-On-LAN enabled PC motherboard that can supply low-level auxiliary power to a

network card when the PC is powered off.

• A Wake-On-LAN network card that can recognize a wake-up packet and signal the PC to power up.

A Wake-On-LAN enabled PC is never completely powered off. It maintains a low-level auxiliary power supply
to the motherboard. Even if the PC is powered off, the network card is always active and monitoring the
network. When a wake-up packet is detected, the card signals the motherboard to power up the PC. With the PC
powered on, maintenance and other support tasks can be performed.

TROUBLESHOOTING

PCI Compatibility

• Early PCI BIOS versions do not properly support the new PCI specifications and may “hang”

when a network card driver tries to load. If this occurs, make sure your BIOS correctly
supports the PCI Local Bus Specification (v2.0 or later) and upgrade your computer BIOS to
the latest version

• Some PCI computers are not self-configuring and require you to perform some or all of the

following functions by motherboard jumper changes and/or BIOS Setup configuration:

o Verify that the PCI slot is an enabled bus-master slot and not a slave PCI slot. The

SMC1255TX-1 must be installed in a PCI bus-master slot. In some computers the
PCI slot must be configured to enable bus mastering. Refer to your PC’s manual and
check the PCI BIOS Setup program to be sure the PCI slot is an enabled bus-master
slot.

o In some computers, you may be required to disable Plug-and-Play in the BIOS Setup

program if resources are not properly assigned between the network card and other
installed cards.

o Some computers may require you to reserve interrupts and memory addresses for

installed ISA cards to prevent PCI cards from using the same settings. Refer to your
PC’s manual and check the PCI BIOS Setup program configuration options for ISA
cards.

o Make sure the PCI slot is configured to support INTA.
o Ensure that INTA for the slot is assigned to a free interrupt (IRQ) number.

Common Installation Problems

Problems are often caused by cabling errors, conflicts with other devices installed in the same
computer, or software that has been configured incorrectly. If you encounter a problem with the
SMC1255TX-1, use the following checklists to identify and correct the problem.

• If you’re computer cannot find the SMC1255TX-1, or the network driver does not install

correctly, check the following items before contacting SMC Technical Support

o Make sure the card is securely seated in the PCI slot. Check for any hardware

problems, such as physical damage to the card’s edge connector.

o Try the card in another PCI bus-master slot. If this fails, test the card in a completely

different system or try using a second SMC1255TX-1 in that particular bus-master
slot.

o Check for resource conflicts in the PCI configuration.
o Make sure your computer is using the latest BIOS available. Contact the

manufacturer of the computer or motherboard for information on updating the BIOS
(e.g. – Dell, Toshiba, etc)

o If there are other network cards in the computer, they may be causing conflicts.

Remove all other cards from the computer and test the SMC1255TX-1 separately. If
you continue to have problems, remove all cards except the SMC1255TX-1 and your
video card.

31

Network Connection Problems

There may be a network connection problem if the LED on the card’s bracket does not light, or if
you cannot access any network resources from the computer. Check the following items before
contacting SMC Technical Support.

• Be sure you are using Category 5 cable for 100 Mbps connections, and that the length of any

cable does not exceed 100 m (328 ft).

• Inspect all network cables and connections. Make sure the network cable is securely attached

to the card’s connector.

• Make sure the correct network card driver is installed for your operating system. If necessary,

try reinstalling the driver.

• Make sure the computer and other network devices are receiving power. If you suspect a

power outlet to be faulty, plug another device into it to verify that it is working.

• If the network card’s speed or duplex mode has been configured manually, check that it

matches that of the attached network device port. Note that it is recommended to set the card
to auto-negotiation when installing the network driver.

• The port on the network device that the card is attached to may be defective. Try using

another port on the device.

• If you cannot access a Windows or NetWare service on the network, check that you have

enabled and configured the service correctly. If you cannot connect to a particular server,
ensure that you have access rights and a valid ID and password.

• If you cannot access the Internet, be sure you have configured your system for TCP/IP.

Cable Types and Specifications

Cable Types and Specifications

Cable Type Max. Length Connector
10BASE-T Cat. 3, 4, 5 100-ohm UTP100 m (328 ft) RJ-45
100BASE-TX Cat. 5 100-ohm UTP100 m (328 ft) RJ-45

Twisted-Pair Cable and Pin Assignments

DO NOT plug a phone jack connector into any RJ-45 port. Use only twisted-pair cables with RJ-45 connectors
that conform to FCC standards.

For 10BASE-T/100BASE-TX connections, a twisted-pair cable must have two pairs of wires. Each wire pair is
identified by two different colors. For example, one wire might be red and the other red with white stripes. Also,
an RJ-45 connector must be attached to both ends of the cable.

Caution: Each wire pair must be attached to the RJ-45 connectors in a specific orientation.

The figure below illustrates how the pings on the RJ-45 connector are numbered. Be sure to hold the connectors
in the same orientation when attaching the wires to the pins.

With 10BASE-T/100BASE-TX cable, pins 1 and 2 are used for transmitting data, and pins 3 and 6 for receiving

Terminology

10BASE-T: IEEE 802.3 specifications for 10 Mbps Ethernet over two pairs of Category 3, 4, or 5 UTP cable.
100BASE-TX: IEEE 802.3u specification for 100 Mbps Fast Ethernet over two pairs of Category 5 UTP cable.

1000BASE-T: IEEE 802.3ab specification for Gigabit Ethernet over four pairs of Category 5 UTP cable.

Adapter: A device used to connect end-user nodes to the network; each contains an interface to a specific type

of computer or system bus, e.g. EISA, ISA, PCI, PCMCIA, CardBus, etc.

Auto-Negotiation: A signaling method that allows each node to define its operational mode (e.g., 1000 Mbps
and half/full duplex) and to detect the operational mode of the adjacent node.

Backbone: The core infrastructure of a network. It is the portion of the network that transports information
from one central location to another central location where it is unloaded onto a local system.

Bandwidth: The difference between the highest and lowest frequencies available for network signals. Also
synonymous with wire speed, the actual speed of the data transmission along the cable.

Collision: A condition in which packets transmitted over the cable interfere with each other. The interference
makes both signals unintelligible.

Collision Domain: Single CSMA/CD LAN segment.

CSMA/CD: CSMA/CD (Carrier Sense Multiple Access/Collision Detect) is the communication method

employed by Ethernet and Fast Ethernet.

DHCP: Dynamic Host Configuration Protocol. This protocol automatically configures the TCP/IP settings of
every computer on your home network.

DNS: DNS stands for Domain Name System, which allows Internet host computers to have a domain name
(such as www.smc.com) and one or more IP addresses (such as 192.34.45.8). A DNS server keeps a database of
host computers and their respective domain names and IP addresses, so that when a domain name is requested
(as in typing "www.smc.com" into your Internet browser), the user is sent to the proper IP address. The DNS
server address used by the computers on your home network is the location of the DNS server your ISP has
assigned.

DSL: DSL stands for Digital Subscriber Line. A DSL modem uses your existing phone lines to transmit data at
high speeds.

End Station: A workstation, server, switch, bridge or router.

Ethernet: A network communication system developed and standardized by DEC, Intel, and Xerox, using

baseband transmission, CSMA/CD access, logical bus topology and coaxial cable. The successor IEEE 802.3
standard provides for integration into the OSI model and extends the physical layer and media with repeaters
and implementations that operate on fiber, thin coax and twisted-pair cable.

35

Fast Ethernet: A 100 Mbps network communication system based on Ethernet and the CSMA/CD access
method.

Full Duplex: Transmission method that allows two network devices to transmit and receive concurrently,
effectively doubling the bandwidth of that link.

Hub: Central connection device for shared media in a star topology. It may add nothing to the transmission
(passive hub) or may contain electronics that regenerate signals to boost strength as well as monitor activity
(active/intelligent hub). Hubs may be added to bus topologies; for example, a hub can turn an Ethernet network
into a star topology to improve troubleshooting.

IEEE: Institute of Electrical and Electronic Engineers.

IEEE 802.3: Defines carrier sense multiple access with collision detection (CSMA/CD) access method and

physical layer specifications.

IEEE 802.3u: Defines CSMA/CD access method and physical layer specifications for 100BASE-TX Fast
Ethernet.

IP Address: IP stands for Internet Protocol. An IP address consists of a series of four numbers separated by
periods, which identifies a single, unique Internet computer host. Example: 192.34.45.8.

ISP: Internet Service Provider. An ISP is a business that provides connectivity to the Internet for individuals
and other businesses or organizations.

Local Area Network (LAN): A group of interconnected computer and support devices. It is made up of servers,
workstations, a network operating system and a communications link. Servers are high-speed machines that
hold programs and data shared by network users. The workstations (clients) are the users' personal computers,
which perform stand-alone processing and access the network servers as required.

LAN Segment: Separate LAN or collision domain.

LED: Light emitting diode is used for monitoring a device or network condition.

MAC Address: MAC (Media Access Control) A MAC address is the hardware address of a device connected

to a network.

Media Access Control (MAC): A portion of the networking protocol that governs access to the transmission
medium, facilitating the exchange of data between network nodes.

MDI / MDI-X: Medium Dependent Interface - Also called an "uplink port," it is a port on a network hub or
switch used to connect to other hubs or switches without requiring a crossover cable. The MDI port does not
cross the transmit and receive lines, which is done by the regular ports (MDI-X ports) that connect to end
stations. The MDI port connects to the MDI-X port on the other device. There are typically one or two ports on
a device that can be toggled between MDI (not crossed) and MDI-X (crossed). Medium Dependent Interface –
X (crossed) - A port on a network hub or switch that crosses the transmit lines coming in to the receive lines
going out.

36

MII: Media Independent Interface, the standard interface for Fast Ethernet—similar to the AUI interface for
traditional Ethernet.

Network Diameter: Wire distance between two end stations in the same collision domain.

PCI: Peripheral Component Interconnect - Local bus for PCs from Intel that provides a high-speed data path

between the CPU and up to 10 peripherals (video, disk, network, etc.). The PCI bus runs at 33MHz supports 32­bit and 64-bit data paths, and bus mastering.

Static IP: If your Service Provider has assigned a fixed IP address; enter the assigned IP address, subnet mask
and the gateway address provided by your service provider.

Subnet Mask: A subnet mask, which may be a part of the TCP/IP information provided by your ISP, is a set of
four numbers configured like an IP address. It is used to create IP address numbers used only within a particular
network (as opposed to valid IP address numbers recognized by the Internet.

Switched Ports: Ports that are on separate collision domains or LAN segments.

Transmission Control Protocol/Internet Protocol (TCP/IP): Protocol suite that includes TCP as the primary

transport protocol, and IP as the network layer protocol.

TCP: Transmission Control Protocol - TCP and UDP (User Datagram Protocol) are the two transport protocols
in TCP/IP. TCP ensures that a message is sent accurately and in its entirety. However, for real-time voice and
video, there is really no time or reason to correct errors and UDP is used instead.

UDP: User Datagram Protocol - A protocol within the TCP/IP protocol suite that is used in place of TCP when
a reliable delivery is not required. For example, UDP is used for real-time audio and video traffic where lost
packets are simply ignored, because there is no time to retransmit. If UDP is used and a reliable delivery is
required, packet sequence checking and error notification must be written into the applications.
