■
During 100Mbs operation, the yellow link light indicates
scrambler lock and the receipt of valid idle codes.
■
The green activity light illuminates when the computer
detects network activity. When the system is connected to a
highly used network, the green activity light will remain on
almost constantly.
■
If Remote Wakeup is enabled, the link and activity lights will
remain functional even when power to the computer is turned
off.
Disabling the
Autosensing
Capabilities
Your computer automatically senses if the attached network
supports 10Mbs or 100Mbs and configures itself accordingly.
This process of determining the maximum network operating
speed is known as autosensing. The computer begins autosensing
whenever it loses a valid network link, for example, if the cable
is disconnected.
In addition to determining the network operating speed, the
computer determined 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. The different modes of operation are:
■
100Base-TX, full-duplex
■
100Base-TX, half-duplex
■
10Base-T, full-duplex
■
10Base-T, half-duplex
If necessary, you can disable the autosensing capabilities and
force the system into the correct operating mode. To set the
network operating mode manually, complete the following
steps:
1. Double-click the Network icon, located in the Control
Panel.
2. Double-click the Compaq Netelligent 10/100 TX
Embedded UTP Controller.
3. Select the Advanced Properties tab.
4. Select Media Speed and change the value from AUTO to
10Mbs or 100Mbs, depending on the capabilities of your
network.
