Configuring IP Settings

Use these guidelines when manually configuring the IP settings:

You can use 0.0.0.0 for the subnet mask only if the default gateway is also 0.0.0.0.
The TFTP server must have an IP address.
The default gateway IP address must be on the same subnet as the host IP address.

Assigning an IP Address

The IP address is the unique logical address identifying each host computer, or node, on a TCP/IP network. An IP address is a 32-bit number expressed as four decimal numbers from 0 to 255 separated by periods. Each IP address has two parts: the network ID and the host ID. The network ID identifies all hosts that are on the same physical network. The host ID identifies a specific host on a network.

Before You Begin

You must unlock the network configuration options and disable DHCP. See "Unlocking the Network Configuration Options" section and "Disabling DHCP" section for details.
