Introduction
The 3Com OfficeConnect 10/100 Network Interface Card 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.

Remote LAN Wakeup

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.
Installation
Warning:
Network cards are sensitive to static electricity To protect the card,
avoid touching its electrical components and always touch the metal
chassis of your computer before handling the card
1. Switch off the computer, unplug the power cord, and remove
the computer’s cover.
2. Select an unused PCI bus-master slot and remove its
protective bracket.
Installation

3. Carefully insert the card and press until all the edge
connectors are firmly seated inside the slot. Then, screw the
card’s bracket securely into the PC’s chassis.
4. Connect the 3Com OfficeConnect 10/100 NIC directly to a
10BASE-T or 100BASE-TX hub or switch 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 (328 ft). When inserting an RJ-45
plug, be sure the tab on the plug clicks into position to ensure
that it is properly seated.
5. Replace the computer’s cover and power it on. The 3Com
OfficeConnect 10/100 NIC 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. See “Troubleshooting” on page 8.
6. A text file is included with each supported operating system to
detail the proper installation procedure. New or updated
drivers can be downloaded from 3Com’s Web site at
www.3com.com.

Troubleshooting
Check the following troubleshooting items before contacting 3Com
Technical Support.
PCI Compatibility
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 program configuration:
• Make sure your BIOS correctly supports the PCI Local Bus
Specification v2.0 or later and upgrade your computer BIOS to
the latest version.
• Verify that the PCI slot is an enabled bus-master slot and not a
slave PCI 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 Set up program to be sure the PCI slot
is an enabled bus-master slot.
• In some computers, you may be required to disable Plug-and-
Play in the BIOS Set up program if resources are not properly
assigned between installed cards.
• Some computers may require you to reserve interrupts and
memory addresses for installed ISA cards to prevent PCI cards
using the same settings. Refer to your PC’s manual and check
the PCI BIOS Set up program configuration options for ISA
cards.
• Make sure the PCI slot is configured to support INTA.
• Be sure that INTA for the slot is assigned to a free interrupt
(IRQ) number.

• Check the BIOS Setup program’s PCI parameters for the slot
wherethe 3ComOfficeConnect10/100 NICisinstalled. Be sure
the slot is configured for level-triggered interrupts instead of
edge-triggeredinterrupts.AnexampleoftypicalPCIparameters
follows:
PCI Slot #: (slot number where the network card
is installed)
Master: Enabled
Slave: Enabled
Latency Timer: 40(range is 20 to 255)
Interrupt Type: Level-Triggered
Interrupt Number: choose any number the BIOS Setup
provides that does not conflict
with another installed card)
Note:
The wording of these parameters varies with different
computers, and not all parameters may be configurable.
Always consult your computer manual for information on changing
motherboard jumper settings and BIOS Setup program
parameters for use with PCI network cards. If you set a
motherboard jumper and modify the computer’s BIOS Setup,
make sure the jumper and BIOS settings match.
Adapter Installation Problems
If your computer cannot find the 3Com OfficeConnect 10/100 NIC
or the network driver does not install correctly, check the following:
• Make sure the adapter 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 bus-master slot. If this fails, test with
another 3Com OfficeConnect 10/100 NIC that is known to
operate correctly.
• Check for resource conflict in the PCI configuration. See
“PCI Compatibility.”
• Make sure your computer is using the latest BIOS available.
• Ifthereareothernetworkadaptersinthecomputer,theymaybe
causing conflict. Remove all other adapters from the computer
and test the 3Com adapter separately.
• Check for a defective computer or PCI bus by trying the adapter
in another computer that is known to operate correctly.

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.
• 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.
• Ifthenetwork card’s speedorduplexmodehasbeenconfigured
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
servicecorrectly. If youcannot connectto aparticular 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.
