The EZ Card 10/100 Mbps Combo Adapter is based on advanced
silicon to maximize throughput and increase the efficiency of your
network. It features a dual-speed, bus-master design, and supports
auto-negotiation and all common networking environments.

The RJ-45 connector supports auto-negotiation, so the port can
configure itself automatically to run at the highest possible
data-transfer rate—10 or 100 Mbps and half or full
duplex—providing the link partner also supports auto-negotiation.

The Wake-On-LAN (WOL) cable allows a WOL-enabled PC to be
managed remotely. Software can be loaded and updated,
configurations changed, data backed up, inventory checked,
viruses removed, device conflicts eliminated and system crashes
repaired from a remote central location. This decreases user
downtime and increases overall productivity.

LED Indicators

The EZ Card network adapter includes at-a-glance LED indicators
to monitor the port connection. Depending on the model, the
LEDs are positioned on the bracket below the port, or are built

NSTALLING THE CARD

Hardware Installation

1. Switch off all computer system components, unplug the

computer, and remove the computer cover.

2. Work in a static-free area and touch the computer chassis often

to equalize static charges.

3. Install the network card into an available bus-mastering PCI

slot.

4. Make sure the network card is completely seated so that no

“gold fingers” are exposed.

Figure 1. Inserting the Network Card

5. Connect the SMC1255FTX-SC directly to your switch, hub or

cable/dsl modem using UTP cable (Category 3, 4 or 5 for
10BASE-T; Category 5 for 100BASE-TX). The maximum
allowable length of UTP cable connections is 100 meters
(328ft). When inserting an RJ-45 plug, be sure the tab on the
plug clicks into position to ensure that it is properly seated.
The SMC1255FTX-SC comes with an SC connector that
supports 100Base-FX fiber connections using 62.5/125 or 50/

4

H

ARDWARE INSTALLATION

125 micron multimode fiber optic cabling. Because SC
connections are keyed, they can only be attached in one
orientation. Connect one end of the fiber cable to the card’s SC
connector and the other end of the cable to the fiber connector
on the other device. Make certain that the device you are
connecting to is specified for 100 Mbps operation.

Figure 2. Connecting the SC connector

6. Replace the computer’s cover and power it on. The

SMC1255FTX-SC should be automatically configured by the
host computer’s BIOS. However, if you have an older
computer, you may have to manually configure the computer’s
BIOS settings.

The RJ-45 connector supports auto-negotiation, so the port can
configure itself automatically to run at the highest possible data
transfer rate (10 or 100 Mbps and half or full duplex) providing
the link partner also supports Auto-Negotiation. The SC fiber
connector enables the SMC1255FTX-SC model to support 100
Mbps transmissions at full and half duplex over 62.5/50/125
micron multimode fiber cable. A fiber cable link operating in
full-duplex mode can extend to remote sites up to 2 km (1.24
miles) away.

7. This model supports a Wake-On-LAN connector. The

Wake-On-LAN (WOL) cable allows a WOL-enabled PC to be
managed remotely. Software can be loaded and updated,
configurations changed, data backed up, inventory checked,
viruses removed, and device conflicts eliminated. This
decreases user downtime and increases overall productivity.
For using the WOL function, connect one end of the 3-pin
WOL cable to connector J1 on the card, and the other end to
the “5V Standby” connector on the computer’s motherboard, as
shown in the following figure. (Refer to your computer’s
installation manual to locate the 5V Standby connector.)

Early PCI BIOS versions do not properly support the PCI
specification 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 changing
motherboard jumpers and/or configuring the BIOS setup program:

• Verify that the PCI slot is an enabled busmaster slot and not a
slave PCI slot. The EZ Card must be installed in a PCI busmaster
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
busmaster slot.

• In some computers, you may be required to disable Plug ‘n Play
(PnP) in the BIOS setup program if resources are not properly
assigned between the network card and other installed cards.

• 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.

Solutions for Common Problems

Basic Troubleshooting

Network 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, use
the checklists and guidelines in this section to try and identify the
problem before contacting SMC Technical Support.

Network Card Installation Problems

If your computer cannot find the EZ Card or the network driver
does not install correctly, check the following items.

• 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.

• Try the card in another PCI busmaster slot. If all fails, test with
another EZ Card that is known to operate correctly.

• Check for resource conflict in the PCI configuration. Refer to
the section “PCI Compatibility” in this chapter.

• If there are other network cards in the computer, they may be
causing conflict. Remove all other cards from the computer and
test the EZ Card separately.

• Check for a defective computer or PCI bus by trying the
network card in another computer that is known to operate
correctly.

• Make sure your computer is using the latest BIOS available.

OLUTIONS FOR COMMON PROBLEMS

Network Connection Problems

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

• Make sure the cable is within IEEE 802.3 Ethernet, or
IEEE802.3u Fast Ethernet standards for the type of network you
are using. Also, make sure cable lengths are within the
requirements specified in “Cables” on page 30.

• 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 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 service on the network, check
that you have enabled and configured the service correctly. If
you cannot connect to a particular server, be sure 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.

Twisted-Pair Cable and Pin Assignments

Caution: DO-NOT plug a phone jack connector into any RJ-45

port. Use only twisted-pair cables with RJ-45 connectors
that conform with 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.

WISTED-PAIR CABLE AND PIN ASSIGNMENTS

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

Straight-Through Wiring

If the twisted-pair cable is to join two ports and only one of the
ports has an internal crossover, the two pairs of wires must be

straight-through.

If the twisted-pair cable is to join two ports and either both ports
are labeled with an “x” (MDI-X) or neither port is labeled with an

“x” (MDI), a crossover must be implemented in the wiring.
