SMC Networks 1255FTX-SC Installation Manual page 3

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/ 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.
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.)
PCI Configuration
In most cases, your network card is automatically configured when
you power-up your computer. In certain computers, however, you
must modify your BIOS by entering your CMOS SETUP utility. For
more information, refer to "PCI Compatibility" on page 27.
