2.3 Configuring of the Ethernet Interface
Explanation
To use the Ethernet communication functions of the CX, the following settings are
required:
Setting the IP Address, Subnet Mask, Default Gateway, and DNS
Consult your system or network administrator in setting parameters such as the IP
address, subnet mask, default gateway, and DNS (domain name system).
• IP address
• Set the IP address to assign to the CX. The default setting is “0.0.0.0.”
• The IP address is used to uniquely identify a device on the Internet when using
TCP/IP. The address is a 32-bit value expressed using four octets (each 0 to
255) with each octet separated by a period as in [192.168.111.24].
• Subnet mask
• Set the mask value used when determining the subnet network address from
the IP address. The default setting is “0.0.0.0.”
• Set the value according to the system or network to which the CX belongs. You
may not need to set the value.
• Default gateway
• Set the IP address of the gateway (router, etc.) used to communicate with other
networks. The default setting is “0.0.0.0.”
• Set the value according to the system or network to which the CX belongs. You
may not need to set the value.
• DNS (Domain Name System)
DNS is a system used to associate names used on the Internet called host names
and domain names to IP addresses. Host names and domain names can be used
to access the network instead of using the IP address, which is a sequence of
numbers. The DNS server manages the database containing the association of
host names and domain names to the IP addresses. If you are specifying the data
(file or e-mail) destination server using a host name in the FTP client settings
(section 2.5) or e-mail transmission function settings (section 2.11), you must enter
the DNS information described here.
• DNS Server
• Set the DNS server address. The default setting is “0.0.0.0.”
• You can specify up to two DNS server addresses, primary and secondary.
When the primary DNS server is down, the secondary DNS server is
automatically looked up for the mapping of the host name/domain name and
IP address.
• Host name
Set the host name of the CX using up to 64 alphanumeric characters.
• Domain name
• Set the name of the network domain that the CX belongs to using up to 64
alphanumeric characters.
• The domain name is appended to the destination host name as a possible
domain if the domain is omitted when the transmission destination (server)
for the data from the CX is looked up on the DNS server. The name of the
transmission destination (server name) is the “FTP server name” specified in
section 2.5.
