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.

The 3Com OfficeConnect 10/100 NIC complies with ACPI and

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

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.

Troubleshooting

9

Check the BIOS Setup program’s PCI parameters for the slot 
where the 3Com OfficeConnect 10/100 NIC is installed. Be sure 
the slot is configured for level-triggered interrupts instead of 
edge-triggered interrupts. An example of typical PCI parameters 
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.

If there are other network adapters in the computer, they may be 
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.

Troubleshooting

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.

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, 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.
