The following items are covered in this section:
■Ethernet Network Structure
■Network Interface Controller (NIC)-Based Alerts
■Wake-On-Lan (WOL) Support
■Interpreting the Network Status Lights
■Disabling the Autosensing Capabilities
■Installing Network Drivers
This section provides information about Ethernet networks and the
hardware connectors and software device drivers that allow you to
access an Ethernet network. Access to a computer network
immediately increases your productivity potential. Once the network
connection is active, you can share resources, such as a printer,
exchange information from computer to computer, and run common
software programs.
The computer comes network-ready, which means that it has an
integrated network controller and network device drivers already
loaded onto the computer hard drive. The computer is ready to make
the network connection.

NIC-Based Alerts
Some NICs feature Alerting Capabilities, which allow a system
administrator to monitor the computer over the network remotely. The
computer can send hardware and operating system alerts over the
network before the operating system is loaded, while the operating
system is loaded, while the computer is in low power states, and when
the computer is powered off. Depending on the NIC model, these
alerts may include:
■System BIOS hang
■Operating system hang
■Processor missing
■Operating temperature exceeded
■Chassis intrusion
■Watchdog
■Heartbeat monitoring
✎NICs featuring Alerting Capabilities comply with Alert Standard
Format (ASF) specification 1.0. RMCP events are not supported due
to lack of security in the ASF 1.0 specification.
NIC-Based Alerts are enabled and configured by installing the
ASF 1.0 agents for the NIC you are using. These are available at
http://www.hp.com. ASF alerts can also be enabled and configured
using DMI or CIM.
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:
Windows 2000
1. Select Start > Settings > Control Panel.
2. Double-click Network Dial-up Connections.

1–4 www.hp.com Network & Internet Communications Guide
Network Communications
3. Double-click Local Area Connection.
4. Click Properties.
5. Click Configure.
6. Click the Power Management tab, then select or clear the check
box to Allow this device to bring the computer out of standby.
Windows XP
1. Select Start > Control Panel.
2. Double-click Network Connections.
3. Double-click Local Area Connection.
4. Click Properties.
5. Click Configure.
6. Click the Power Management tab, then select or clear the check
box to Allow this device to bring the computer out of standby.
✎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 or at http://www.compaq.com.
✎For information on filtering out unintentional Wake-On-LAN events,
refer to any additional documentation provided for the NICs
advanced diagnostics/configuration utility.
Interpreting the Network Status Lights
Select Ethernet network interface controllers include network status
lights:
■Link light—illuminates when the system is physically connected
to an active network.
■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.

Network & Internet Communications Guide www.hp.com 1–5
Network Communications
■Operating Speed light—illuminates during 1000 Mbps or
100 Mbps operation. The color of the light identifies the
operating speed.
Some NICs include only two network status lights where link
(light on) and activity (light blinking) are indicated by one light and
1000-Mbps or 100-Mbps operation is indicated by the second light.
The integrated NIC has two network status lights on the NIC
connector:
■Link/Activity light—Illuminates green when physically linked to
the network and blinks on and off to indicate network activity.
■Operating Speed light—Illuminates green when operating at
1000 Mbps, yellow when operating at 100 Mbps, and is not
illuminated when operating at 10 Mbps.
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.
If necessary, you can disable the Auto-Negotiation capabilities and
force the system to operate in one mode only.
Windows 2000
1. Select Start > Settings > Control Panel.
2. Double-click Network Connections.
3. Double-click Local Area Connection.

Installing Network Drivers
The device drivers in the network software enable the computer to
communicate with the network. Because Compaq does not know
which network operating system you’ll be using, the computer comes
ready to work with several different environments.
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 Windows 2000, Windows XP
Professional, and Windows XP Home 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 HP. If it ever becomes
necessary to reinstall the operating system, use the Compaq Restore
Plus! CD.
Complete instructions for installing the network device drivers are
available as ASCII text files, located in the C:\COMPAQ\NIC
directory. Use the instructions found in the subdirectory that relates to
the network environment.
Install the correct device drivers according to the operating system
you are using, as listed below.
Windows 2000
Follow the instructions in the ASCII text files located in the
C:\CPQNET directory. Use the instructions found in the subdirectory
that relates to the network environment.
Windows XP
1. Select Start > Control Panel.
2. Double-click Network Connections.
3. Double-click the New Connection Wizard icon and follow the
instructions on the screen.

Internet Communications
The following items are covered in this section:
■Choosing an Internet Service Provider
■Content Advisor
■Solving Internet Access Problems
Choosing an Internet Service Provider
An Internet service provider (ISP) gives you the dial-up (telephone or
cable networking) access and software you need to connect to the
Internet. Most ISPs also offer e-mail, access to newsgroups, space to
create Web pages, and technical support. Some ISPs offer commercial
services, such as domain hosting, to companies and individuals
wanting to do business on the Internet. You can choose from local and
national ISPs.
An online service provider, such as MSN or America Online (AOL),
offers special features, content, and technical support in addition to
providing access to the Internet. An online service provider may
provide a categorized or customizable home page that makes it easy
for you to find some of the most popular and useful sites on the
Internet.
To find the provider that is right for you:
■Look in the Yellow Pages
■Ask a friend or colleague for recommendations
■If you have access to the Internet already, you can use a search
engine, such as Google, to help you locate an ISP or online
service provider.

Internet Communications www.hp.com Network & Internet Communications Guide
Internet Communications
■ISPs typically offer a variety of service plans for different
customers’ needs. Be sure to review and compare plans, services
offered, and price to find the provider that is right for you and
your needs.
Content Advisor
The Internet provides you with access to a wide variety of
information, but some information may not be suitable for every
viewer.
With Content Advisor, you can:
■Control Internet access
■Set up a password
■Set up a list of Web sites that people who use the computer cannot
view
■Adjust the types of content people who use the computer can
view with or without your permission
