Network Communications Guide
The following items are covered in this guide:
■NIC-Based Alerts
■Wake-On-Lan (WOL) Support
■Interpreting the Network Status Lights
■Disabling the Autosensing Capabilities
■Installing Network Drivers
NIC-Based Alerts
Some NICs feature Alerting Capabilities, which allows a system
administrator to remotely monitor the computer over the network.
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
✎NIC-Based Alerts are enabled by installing the Alert on LAN agents
from Intel. These are available at http://www.compaq.com.

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 Start > Control Panel > Hardware > 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 by restarting the computer and pressing the
F10 key when “F10” appears in the lower right corner of the
screen.
2. Select the Advanced tab > Device Options > PME Wakeup
Events.
3. Using the right or left arrow key, select enable or 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 or at http://www.compaq.com.
✎For information on WOL filtering, refer to any additional
documentation provided for the NICs advanced
diagnostics/configuration utility.

Network Communications Guide
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.
✎The integrated NIC has two network status lights on the NIC
connector:
■Link light/Activity (Green)—Illuminates green when
physically linked to the network and blinks on and off to
indicate network activity.
■100Base-TX/10TX (Amber)—Illuminates amber when
operating at 100-Mbs and is not illuminated when operating
at 10-Mbs.
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.

4 Network Communications Guide
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 NT 4.0 and
Windows 98 or later 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 reinstallation of the operating system ever
becomes necessary, use the Compaq Restore CD or Restore Plus! CD.
