NPort S8000 Series Basic Settings and Device Server Configuration
5-7
The IP address must be unique within the network (otherwise, the NPort S8000 will not have a valid connection
to the network). First time users can refer to Chapter 3, Initial IP Address Configuration, for more information.
You can choose from four possible IP Configuration modes—Disable (Static) , DHCP, and BOOTP—located
under the web console screen’s IP configuration drop-down box.
Auto IP Configuration
Setting Description Factory Default
Disable Set up the NPort S8455-MM-SC’s IP address manually. Disable
By DHCP The NPort S8455-MM-SC’s IP address will be assigned
automatically by the network’s DHCP server.
By BOOTP The NPort S8455-MM-SC’s IP address will be assigned
automatically by the network’s BOOTP server.
ATTENTION
In Dynamic IP environments,
the firmware will retry 3 times every 30 seconds until network settings are
assigned by the DHCP or BOOTP server. The Timeout for each try increases from 1 second, to 3 seconds, to 5
seconds.
If the DHCP/BOOTP Server is un
available, the firmware will use the default IP address (192.168.127.254),
N
etmask, and Gateway for IP settings.
IP Address
Setting Description Factory Default
IP Address
of the NPort
S8455-MM-SC
Identifies the NPort S8455-MM-SC on a TCP/IP network. 192.168.127.254
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 addresses to identify and talk to each other over the network. Choose a proper
IP address which is unique and valid in your network environment.
Subnet Mask
Setting Description Factory Default
Subnet mask of the
NPort S8455-MM-SC
Identifies the type of network to which the NPort S8455-MM-
SC
is connected (e.g., 255.255.0.0 for a Class B network, or
255.255.255.0 for a Class C network).
255.255.255.0
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 NPort will use the subnet mask to check
whether the desired TCP/IP host specified in the packet is on the local network segment. If the address is on the
same network segment as the NPort, a connection established directly from the NPort. Otherwise, the
connection is established through the given default gateway.
Default Gateway
Setting Description Factory Default
Default Gateway
of the
NPort S8455-MM-SC
The IP address of the router that connects the LAN to an
outside network.
None
A gateway is a network gateway that 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 NPort 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 the network administrator.
