■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
■Wireless Networks
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 can be monitored in the following states:
■System BIOS hang—On action
■Operating system hang—On action
■Processor missing—On power up
■Operating temperature exceeded—On action
■Chassis intrusion—On power up/or on action if system is running
■Watchdog—On action (same as Operating system hang)
■Heartbeat monitoring—Always
✎NICs featuring Alerting Capabilities comply with Alert Standard
Format (ASF) specification 2.0 and support Remote Management and
Control Protocol (RMCP) based alerts. ASF 1.0 implementations will
not support RMCP due to lack of security in the ASF 1.0
specification.
NIC-Based Alerts are enabled and configured by installing the ASF
2.0 agents for the NIC you are using. These are available at
www.hp.com. ASF alerts can also be enabled and configured using
the Common Information Model (CIM).

Network Communications
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.
■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.

Network Communications
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.

Installing Network Drivers
The device drivers in the network software enable the computer to
communicate with the network. Because HP 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 XP Professional,
Windows XP Home, and Windows 2000 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
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.

Wireless Networks
A wireless LAN provides the same functionality of a wired network,
but it eliminates the need to install networking cables and other
networking equipment, making it easier to deploy.
A wireless LAN can be configured for two different modes of
operation. While each method has its advantages, one may be better
suited for your needs. Review the following configuration
information to determine which mode is best for you.
■Ad-hoc Network
■Access Point (Infrastructure) Network
Ad-hoc Network
An Ad-hoc network is the simplest to deploy and is ideal for small
offices. Ad-hoc wireless networks can be comprised of two or more
wireless clients configured to communicate with one another. All
Ad-hoc clients communicate directly with each other without using
an Access Point (AP). As a user on this type of network, you are able
to quickly build up a wireless network in order to share files with
other employees, print to a shared office printer, and access the
Internet through a single shared connection.
Ad-hoc networking is cost effective because no other devices’
components are needed (access points, hubs, or routers) in order to set
up a network. However, with Ad-hoc networking, your computer is
only able to communicate with other nearby wireless clients.
Access Point (Infrastructure) Network
An Access Point network is also referred to as an “Infrastructure”
network. The key difference between a wireless Access Point
network and an Ad-hoc network is the addition of one extra
element—the Access Point. The Access Point serves as the focal
point for all data traffic on your wireless network, optimally
managing all wireless data transactions.
The Access Point extends the range of the wireless LAN. Each
wireless client computer can communicate with other computers
equipped with wireless devices that are within the range of the Access
Point.

1–10 www.hp.com Network & Internet Communications Guide
Network Communications
Additionally, the wireless Infrastructure can provide access to an
existing wired LAN. This link allows computers on the Infrastructure
wireless LAN to access the other wired LAN’s resources and tools,
including Internet access, email delivery, file transfer, and printer
sharing. HP can provide all of the installation services you need to
extend your wired LAN with a wireless LAN.
In addition to the computers that will connect to a wireless network,
you only need two other kinds of equipment to get your Access Point
wireless network up and running:
■Access Points: wireless transmitters that connect every user
within range to the wireless LAN. You can install as many access
points on your network as you need, and add new ones easily as
your network grows, so you can cover an entire suite of offices
with a single wireless LAN. Each access point requires two
connections:
❏A standard outlet for power
❏An Ethernet connection to your existing wired LAN or
incoming Internet connection
■Wireless LAN cards: the wireless equivalent of a network
interface card (NIC) that allow a PC to communicate with the
wireless network. Many HP computers come with built-in
wireless LAN cards so they are ready out of the box to connect to
a wireless network. If your PC doesn't have a wireless card, you
can easily add one. Refer to the Hardware Reference Guide on
the Documentation CD for installation instructions.
Advantages of Wireless Networking
Wireless local area networking (WLAN) brings new levels of
flexibility and accessibility to your business. The many advantages of
wireless networking include:
■There is no need to install labor-intensive and expensive wiring in
a workplace.
■Entire workplaces can be added or moved with minimal
downtime.
■Workers can rearrange their workplaces without being tied to a
wall jack for network access.

Network & Internet Communications Guide www.hp.com 1–11
Network Communications
■A WLAN can often be installed faster and more cost-effectively
than a wired network.
■Additional computers can be added to a WLAN quickly and with
minimal cost.
■WLANs are potentially easier to maintain and manage than wired
networks.
■Wireless local area networks give workers the freedom to access
real-time business information anytime and anywhere within
your office or campus environment.
■Outside the enterprise, public wireless LANs can deliver secure,
high speed connectivity and convenient availability of email,
Internet, and print capabilities.

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) provides you with access (dial-up,
cable, DSL, or wireless) 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.
