a gateway IP address. Consult your network administrator if you need
assistance.

Subnet Mask — An IP address mask that is consistent with your local
area network. Consult your network administrator if you need
assistance.
To help you determine if you need to make changes to the NBX system IP
settings, see
Table 21 , later in this section. To avoid address conflicts with
devices on your local network, change the IP settings of NBX system
before you connect the system to the LAN.
Summary of how to change the IP settings of the NBX system:
■
Temporarily change the IP address of your computer to conform with
the default IP settings of the NBX system.
■
Connect your computer to the NBX system.
■
Use the NBX NetSet utility to modify the IP settings of the NBX system.
■
Restore the IP settings of your computer and reconnect it to the LAN.
■
Connect the NBX system to your local network.
To change the IP settings of the NBX system:
1 Use a category 5 Ethernet crossover cable to connect the computer’s
network interface card (NIC) directly to your NBX system Ethernet port.
By connecting the computer directly to the NBX system, you isolate the
system from the network and eliminate the influence of routers and proxy
servers.
2 Record the existing IP settings on the computer so you can restore them
later.
3 Change the IP settings of your computer to:
CAUTION: Do not set your computer address to 192.168.1.19 2 because
that IP address is used temporarily during system startup. If you use that
address for your computer, a conflict results and the system might not
start properly.
4 Reboot the computer so that the new settings take effect.
