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
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.
