Connect Ethernet
The drivers for the Ethernet interface are pre-installed. A wait period of approxima-
tely 30 results if no Ethernet cable in inserted or no active node is found during the
startup of the operating systems Windows 98 or Windows NT.
Note
A class 5 Ethernet cable is necessary for interface operation at 100 Mbit/s.
If you do not want to use the Ethernet interface, you can turn it off in the BIOS
setup (setting disabled). This results in no waiting period.
In the BIOS setup, the following settings are possible for the Ethernet interface:
Note
Disabled: Ethernet deactivated.
The Ethernet interface hardware is turned off. It is not possible to
operate the interface within the operating system.
Enabled: Ethernet activated.
It is possible to plug in and operate the network cable at any time later
during operation (hot plug).
If no cable is plugged in when the system starts up, the device checks
whether or not an Ethernet cable is inserted for about 30 seconds when
it first boots. If there is an active network connection, there are no noti-
ceable delays.
