Note -
You can configure only one Ethernet interface during installation of the
operating system. To configure additional interfaces, see "How to Add an Ethernet
Interface" on page 198.
What to Do
1. Assign a host name to the machine.
The host name must be unique within the network. It can be made up of
characters and numbers. Do not use a dot in the host name. Do not begin the
name with a number or a special character.
2. Determine the IP address for the interface.
Your network administrator must assign an IP address. Each network device or
interface must have a unique IP address.
3. Resume the installation of the system.
See "How to Install the Enterprise 250 Server" on page 44. When installing the
operating system, you may be prompted to enter the host name and IP address of
the machine.
Note -
If you have installed a PCI card as a second Ethernet interface, the
operating system asks you to select a primary network interface and then
prompts you for its host name and IP address. You must configure the second
interface separately, after the operating system is installed. See "How to Add an
Ethernet Interface" on page 198.
Note - This system conforms to the Ethernet 10/100BASE-T standard, which
states that the Ethernet 10BASE-T link integrity test function should always be
enabled on both the host system and the Ethernet hub. If you have problems
verifying connection between this system and your hub, verify that the Ethernet
hub also has the link test function enabled. See "Network Communications
Failure" on page 267 and refer to the manual provided with your hub for more
information about the link integrity test function.
What Next
After completing this procedure, the Ethernet interface is ready for operation.
