A netmask is used to group network hosts into subnets. When a packet is sent out over the network,
the NPort W2004 will use the netmask to check whether the desired TCP/IP host specified in the
packet is on the same subnet as the NPort. If the address is on the same subnet, a connection is
established directly between the NPort W2004 and the host. If the host is not on the same subnet,
the packet is sent to the Gateway address.
Gateway
Setting Factory Default Necessity
E.g., 192.168.1.1 None Optional
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. NPort W2004 needs to know the IP address of your network’s 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.
ATTENTION
In Dynamic IP environments, the firmware will make 3 requests to the DHCP server every 30
seconds until network settings are assigned by the DHCP server. The Timeout for each try
increases from 1 second, to 3 seconds, to 5 seconds. If the DHCP Server is unavailable, the
firmware will use the default IP address (192.168.126.254), Netmask, and Gateway for IP
settings.
WLAN Configuration
Network Configuration
NPort W2004 supports the IEEE 802.11b wireless network interface.
The supported IP configurations are static and dynamic (DHCP). Users can set up the IP
configuration via the serial console, or the Web/Telnet consoles through the NPort’s Ethernet
