3.13 Server Configuration (Option 0 Network Configuration)
These are the unit’s basic network parameters. The following parameters are displayed when you select
Server(Option 0).
IP Address : (000) .(000) .(000) .(000)
Set Gateway IP Address (N)
Netmask: Number of Bits for Host Part (0=default) (0)
Change telnet config password (N)
Change DHCP device name (not set) ? (N) ?
3.13.1 IP Address
DHCP is not used to assign IP addresses, enter the IP address manually. The IP address must be set to a
unique value in the network. Enter each octet and press Enter between each section. The current value displays
in parentheses.
If DHCP is used, the third octet of the IP address sets the BootP/DHCP/AutoIP options. The following table
shows the bits you can manually configure to force the XPort to disable AutoIP, DHCP, or BootP. To disable an
option, set the appropriate bit.
Options Bit
AutoIP 0
DHCP 1
BootP 2
For example, if the third octet is 0.0.5.0, the AutoIP and BootP options are disabled; only DHCP is enabled. (The
value 5 results from adding the binary equivalents of 0 and 2.) This is the most common setting when using
DHCP.
3.13.2 Set Gateway IP Address
The gateway address, or router, allows communication to other LAN segments. The gateway address should
be the IP address of the router connected to the same LAN segment as the unit. The gateway address must
be within the local network. The default is N (No), meaning the gateway address has not been set. To set the
gateway address, type Y and enter the address.
3.13.3 Netmask: Number of Bits for Host Part
A netmask defines the number of bits taken from the IP address that are assigned for the host section.
Note: Class A: 24 bits; Class B: 16 bits; Class C: 8 bits.
The unit prompts for the number of host bits to be entered, then calculates the netmask, which is displayed
in standard decimal-dot notation when the saved parameters display (for example, 255.255.255.0).

Network Class Host Bits Netmask
A 24 255.0.0.0
B 16 255.255.0.0
C 8 255.255.255.0
