the system to the LAN. The IP configuration required to enable access to
NetSet depends on the current IP environment.
Table 22 describes possible network environments and the configuration
needed to enable IP connectivity to the NBX 100.

NBX 100 Configuration
No IP networking
currently in use You do not need to change the IP settings in the NBX 100,
but you probably need to configure the IP settings in the
computer you use to communicate with NetSet.
The computer must have an Ethernet network interface
card, IP connectivity software installed and configured, and
a web browser. (See the operating system documentation
for information about installing and configuring IP
connectivity software.) Set the computer’s IP parameters to
the following:
■
IP address: 192.168.0.0
■
Subnet mask: 255.255.255.0
■
Default gateway: 0.0.0.0
If you connect the LAN to the Internet at some future date,
the Internet service provider will provide you with
instructions on how to configure the IP settings of devices
on the network. You will need to change the IP settings of
the NBX 100 at that time.
Private IP network, no
subnets You probably need to change the NBX 100 IP address to
conform with the existing IP addressing scheme. You must
change the NBX 100 IP address (192.168.0.0) if that address
is already in use on the network.
Private IP network,
with subnets You probably need to change the NBX 100 IP address to
conform with the existing address space. You must change
the NBX 100 IP address (192.168.0.0) if that address is
already in use on the network. You must change the NBX
100 subnet mask (255:255:255:0) if it does not conform to
the network subnet scheme. You must change the NBX 100
default gateway from 0.0.0.0 to the IP address of the
default gateway for the subnet where you install the NBX
100.
Internet connectivity;
addresses provided by
the Internet Service
Provider. You must change the NBX 100 IP address, default gateway,
and possibly the subnet mask. Ask the ISP to provide a fixed
IP address (the NBX 100 NCP does not support DHCP or
BOOTP), a subnet mask, and default gateway.
