Network connections
The IBM 10/100 Ethernet Mini-PCI Adapter with 56K Modem by 3Com (referred to as
the 3Com 10/100 Mini-PCI Ethernet adapter in this section) provides superior LAN
technology that is built into your notebook computer.
Network cabling requirements
You must use a twisted-pair cable that complies with the Electronic Industries
Association/ Telecommunications Industries Association (EIA/TIA) T568B Commercial
Building Wiring Standard and the Technical Services Bulletin TSB38 standards for
quality, distance, and connectors.
Twisted-pair cable consists of copper wires surrounded by an insulator. Two wires are
twisted together (the twisting prevents interference problems) to form a pair, and the pair
forms a circuit that can transmit data. A cable is a bundle of one or more twisted pairs
surrounded by an insulator.
Unshielded twisted pair (UTP) is the most commonly used type of twisted-pair cable.
Shielded twisted pair (STP) is a twisted-pair cable that provides protection against
crosstalk. Twisted-pair cable is now commonly used in Ethernet, Fast Ethernet, and other
network topologies.
The following table includes descriptions and the length requirements for the twisted-pair
cables that work with network protocols.

Network wake-up features
This section contains information on the Remote Wake-up and Wake on LAN features.
Remote Wake-up (from standby state)
The Remote Wake-up feature enables you to remotely turn on a networked computer that
has gone into standby mode by sending a wake-up packet through the LAN from another
computer.

2-4 IBM 10/100 Ethernet Mini-PCI Adapter with 56K Modem by 3Com User’s Guide
Notes:
1. The Remote Wake-up feature is supported by Windows 2000 and Windows 98
Second Edition ACPI. If you have another version of Windows 98, check with your
network administrator to see if that version supports the Remote Wake-up feature.
2. Consult your network administrator before turning on the Remote Wake-up feature.
To enable the Remote Wake-up feature, you will also need to perform the following
procedure:
a. In the Device Manager window, select 3Com 10/100 Mini PCI Ethernet
Adapter.
b. Click Properties.
c. Click the Power Management tab.
d. Place a check in the Allow this device to bring the computer out of standby
check box.
You can use Remote Wake-up to awaken the computer in one of the following ways:
1. You can wake your computer through a remote management application. This
application sends what is often called a magic or special packet.
2. You can use TCP/IP to “ping” the computer system through an IP address that
identifies the computer.
3. You can use the Network Neighborhood settings to locate the computer and wake it
up. Windows recognizes the Advanced Configuration and Power Interface (ACPI)
standard, which defines the different power states for the computer. The 3Com
10/100 Mini-PCI Ethernet adapter is also compliant with the ACPI standard and
provides remote wake-up capabilities through the Windows operating system.
To support Remote Wake-up, your notebook computer must have the following features:
• BIOS that supports Remote Wake-Up
• Operating system that supports Remote Wake-up
• ACPI capability
For more information on Remote Wake-up, Wake on LAN, or ACPI, refer to your
Windows documentation or your network administration documentation.
Wake on LAN (from power-off state)
Attention: The Wake on LAN or Plug-In-and-Go feature can be enabled only by a
network administrator, because it is used to remotely administer to the notebook computer.
Wake on LAN (WOL), also called Plug-In-and-Go (PIG), enables a remote management
application to send amagic packet to remotely start your notebook computer. When WOL
is enabled and ac power applied, a computer can be turned off and then remotely turned on
when it receives a magic packet. The WOL feature is usually used by network
administrators to provide system services to the network during non-peak hours.
Advanced network settings
