LAN Connection
If you have connected your board to a LAN, the board will either obtain
a dynamic IP address using DHCP, or a static IP address stored in flash
memory. If you do not know whether or not your LAN supports DHCP,
it is easiest to try DHCP first.
DHCP
Upon reset, the web server will attempt to acquire an IP address via the
DHCP protocol. The board will continue to attempt DHCP self-
configuration for two minutes. You can determine if DHCP has
succeeded, or if it is still in progress, by reading status messages on the
LCD screen. If your LAN does not support DHCP then DHCP
configuration will ultimately fail, and the web server will default to a
static IP address.
If DHCP succeeds, the board will display a success message and the IP
address on the LCD screen. The web server is now ready to display web
pages. See “Browsing to Your Board” on page C–5 to continue.
Static IP Address
If the DHCP process fails, the board will use a static IP address stored in
flash memory. You need to obtain a safe IP address in your LAN's subnet
from your system administrator. Once you know a safe IP address, you
can assign it to your board using the steps below.
These steps send IP configuration data to the board via an Altera JTAG
download cable, such as the USB-Blaster cable.
1. Install the Nios II development tools, connect the JTAG download
cable, and apply power to the board, as described in the Nios II
Development Kit, Getting Started User Guide.
2. Choose Start > Programs > Altera > Nios II Development Kit >
Nios II SDK Shell to open the Nios II SDK Shell. A shell window
appears with a command prompt.
3. Press the SW9 button labeled Factory Config on the board.
4. At the Nios II SDK Shell command prompt, type:
nios2-terminal<Enter>
