5-1.3.3 ARP and Telnet: If a serial port is unavailable, you can use the Address Resolution Protocol (ARP) method
from UNIX and Windows-based systems to assign a temporary IP address.
To assign a temporary IP address:
a. On a UNIX or Windows-based host, create an entry in the host's ARP table using the intended IP address and
the hardware MAC address of the Xport, which should be available on the rear-panel of the unit. Make sure
that the intended IP is reachable with the current network settings of the host. The following example uses an
IP of 192.12.3.77. Substitute the desired address in it’s place, and the MAC address of the Xport in place of
the 00:20:4a:xx:xx:xx
arp -s 191.12.3.77 00:20:4a:xx:xx:xx (Unix)
arp -s 191.12.3.77 00-20-4a-xx-xx-xx (Windows)
b. Open a Telnet connection to port 1. The connection fails quickly, but the unit temporarily changes its IP
address to the one designated in this step.
telnet 191.12.3.77 1
c. Open a Telnet connection to port 9999, and press Enter within three seconds to go into Setup Mode. If you
wait longer than three seconds, the unit reboots and you will have to repeat Step 2.
telnet 191.12.3.77 9999
d. Select 0 (Server Configuration) and follow the prompts until you get to IP address.
e. Enter the new IP address, subnet mask, and gateway (if applicable).
f. Select 9 to save and exit Setup Mode. The unit performs a power reset.
5-1.3.4 DHCP: The unit ships with a default IP address of 0.0.0.0, which automatically enables DHCP. If a DHCP
server exists on the network, it provides the unit with an IP address, gateway address, and subnet mask when the unit
boots up.
The DeviceInstaller software can be used to search the network for the DHCP assigned IP address and add it to the
list of devices retrieved.
NOTE
This DHCP address does not appear in the unit’s Setup Mode or in Web Manager. You can
determine your unit’s DHCP-assigned IP address in Monitor Mode. When you enter Monitor Mode
from the serial port with network connection enabled and issue the NC (Network Communication)
command, you see the unit’s IP configuration.
5-1.3.5 AutoIP: The unit ships with a default IP address of 0.0.0.0, which automatically enables Auto IP within the
unit. AutoIP is an alternative to DHCP that allows hosts to obtain an IP address automatically in smaller networks that
may not have a DHCP server. A range of IP addresses (from 169.254.0.1 to 169.254.255.1) has been explicitly
reserved for AutoIP-enabled devices. Do not use this range of Auto IP addresses over the Internet.
 If your unit cannot find a DHCP server, and you have not manually assigned an IP address to it, the unit
automatically selects an address from the AutoIP reserved range. Then, your unit sends out a (ARP) request
to other nodes on the same network to see whether the selected address is being used.
 If the selected address is not in use, then the unit uses it for local subnet communication..
 If another device is using the selected IP address, the unit selects another address from the AutoIP range and
reboots. After reboot, the unit sends out another ARP request to see if the selected address is in use, and so
on.
