Network Communications Guide

The following items are covered in this guide:

■Wake-On-LAN (WOL) Support

■Interpreting the Network Status Lights

■Disabling 802.3u Auto-Negotiation Capabilities

■Installing Network Drivers

✎This platform has been configured with a PCI NIC to provide

enhanced performance. Please ensure that you connect your network

cable to the standard RJ-45 port located on the PCI card.

Wake-On-LAN Support (WOL)

Wake-On-LAN (WOL) can be enabled and disabled in Windows

2000 and Windows XP.

To enable or disable Wake-On-LAN:

1. Select Device Manager > NIC > Properties.

2. Select the Power Management tab.

3. Select or de-select Allow this Device to Bring the Computer

out of Standby.

Or,

1. Run Computer Setup and select Device Options from the

Advanced menu.

2. Set PME wakeup events to enable/disable.

✎For more information on Wake-On-LAN, refer to the online Desktop

Management Guide or to the Remote Management Administrators

Guide. The Remote Management Administrators Guide is included

with the Remote Management Setup Utilities and is available on the

Support Software CD for Compaq Desktop, Portable, and

Workstation Products or at the Compaq Web site at www.compaq.com.

✎For information on WOL filtering, refer to any additional

documentation provided for the NIC’s advanced

diagnostics/configuration utility.

Interpreting the Network Status Lights

Select Ethernet network interface controllers include network status

lights:

■The link light illuminates when the system is physically

connected to an active network.

■The activity light illuminates when the computer detects network

activity. When the system is connected to a highly used network,

the activity light will remain on almost constantly.

■The 100Base-TX light illuminates during 100-Mbs operation.

Some NICs include only two network status lights where link (light

on) and activity (light blinking) are indicated by one light and

100-Mbs operation is indicated by the second light.

Disabling 802.3u Auto-Negotiation Capabilities

Auto-Negotiation NICs automatically determine the maximum

network operating speed and duplex capabilities of the attached

network and configure themselves on the highest common

combination. The computer begins Auto-Negotiation whenever it

obtains a valid network link, or when the NIC driver is loaded.

In addition to determining the network operating speed, the computer

determines if full-duplex is supported. Full-duplex systems can

transmit and receive information on the network simultaneously.

Half-duplex systems cannot transmit and receive simultaneously.

Network Communications Guide 3

Network Communications Guide

If necessary, you can disable the Auto-Negotiation capabilities and

force the system to operate in one mode only.

1. Select the Network icon, located in the Control Panel.

2. Select the appropriate NIC in the list box and click Properties.

3. Change the Speed and Duplex values from Automatic/Auto

Duplex to the appropriate values, depending on the capabilities

of your network.

4. Exit the Network control application. You will be prompted to

restart your computer for the changes to take effect.

Refer to the documentation provided with the network controller for

additional information.

✎100Base-TX operation requires the use of Category 5 UTP cable with

an RJ-45 network connection.

Installing Network Drivers

The device drivers for the network controller enable the drivers to

load correctly in the operating system used, allowing communication

with the network.

✎Device drivers are supplied for the Microsoft Windows 2000 and

Windows XP operating systems, depending on the computer model.

If you are using another operating system, device drivers may be

installed from media included with the network operating system or

are available from Compaq. If reinstallation of the operating system

ever becomes necessary, use the Compaq Restore Plus! CD.
