NE-4100 Series User’s Manual Web Console Configuration
6-6
IP configuration
Method Function Definition
Static User defined IP address, Netmask, Gateway.
DHCP DHCP Server assigned IP address, Netmask, Gateway, DNS, and Time Server
DHCP/BOOTP
DHCP Server assigned IP address, Netmask, Gateway, DNS, and Time
Server, or BOOTP Server assigned IP address
BOOTP BOOTP Server assigned IP address
IP configuration is a required field. The default setting is Static.
ATTENTION
In Dynamic IP environments, the module will attempt to obtain an IP address from the DHCP or
BOOTP server 3 times at 30-second intervals. The timeout for the first try will be 1 second, the
second try will be to 3 seconds, and the last try will be 5 seconds.
If the DHCP/BOOTP Server is unavailable, the module will use the default IP address
(192.168.127.254), netmask, and gateway settings.
IP Address
Setting Factory Default Necessity
E.g., 192.168.1.1
(IP addresses of the form x.x.x.0 and
x.x.x.255 are invalid.)
192.168.127.254 Required
An IP address is a number assigned to a network device, such as a computer, as a permanent
address on the network. Computers use the IP address to identify and talk to each other over the
network. Choose a proper IP address which is unique and valid in your network environment.
Netmask
Setting Factory Default Necessity
E.g., 255.255.255.0 255.255.255.0 Required
A subnet mask represents all the network hosts at one geographic location, in one building, or on
the same local area network. When a packet is sent out over the network, the module will use the
subnet mask to check whether the host specified in the packet is on a local network segment. If the
address is on the same network segment as the module, a connection is established directly from
the module. Otherwise, the connection is established through the default gateway.
Gateway
Setting Factory Default Necessity
E.g., 192.168.1.1 None Optional
A gateway acts as an entrance to another network. Usually, the computers that control traffic
within the network or at the local Internet service provider are gateway nodes. The module needs
to know the IP address of the default gateway computer in order to communicate with the hosts
outside the local network environment. For correct gateway IP address information, consult your
network administrator.
