network card on the other (using a 10Base-TG twisted pair cable). The ca-
ble modem then provides a dedicated Internet connection with a fixed IP
address.
Depending on the instructions provided by your ISP, when configuring the
network card either select ‘Automatic Address Setup (via DHCP)’ or ‘Static
Address Setup’. Most providers today use DHCP. A static IP address often
comes as part of a special business account.
For further information about the configuration of cable modems, read the
Support Database article on the topic, which is available online at http:

21.4.3 S/390, zSeries: Configuring Network Devices
The qeth-hsi Device
To add a qeth-hsi (IBM Hipersocket) interface to the installed system,
start the YaST network card module (‘Network Devices’ ➝ ‘Network
Card’). Select one of the devices marked ‘IBM Hipersocket’ to use as the
READ device address and click ‘Configure’. In the ‘Network address setup’
dialog, specify IP address and netmask for the new interface and leave the
network configuration by pressing ‘Next’ and ‘Finish’.
The qeth-ethernet Device
To add a qeth-ethernet (IBM OSA Express Ethernet Card) interface to
the installed system, start the YaST network card module (‘Network De-
vices’ ➝ ‘Network Card’). Select one of the devices marked ‘IBM OSA Ex-
press Ethernet Card’ to use as the READ device address and click ‘Config-
ure’. Enter the needed port name, some additional options (see the Linux
for zSeries and S/390: Device Drivers, Features, and Commands manual for ref-
erence), your IP address, and an appropriate netmask. Leave the network
configuration with ‘Next’ and ‘Finish’.
The ctc Device
To add a ctc (IBM parallel CTC Adapter) interface to the installed sys-
tem, start the YaST network card module (‘Network Devices’ ➝ ‘Network
Card’). Select one of the devices marked ‘IBM parallel CTC Adapter’ to use
as your read channel and click ‘Configure’. Choose the ‘S/390 Device Set-
tings’ that fit your devices (usually this would be ‘Compatibility mode’).
Specify both your IP address and the IP address of the remote partner. If
needed, adjust the MTU size via ‘Advanced’ ➝ ‘Detailed Settings’. Leave
the network configuration with ‘Next’ and ‘Finish’.
