Appendix C: Alternative Methods of Assigning an IP Address
XPress DR+ User Guide 107
You can disable AutoIP by setting the unit’s IP address to 0.0.1.0. This setting enables
DHCP but disables AutoIP.
BOOTP
Similar to DHCP, but for smaller networks. Automatically assigns the IP address for a
specific duration of time.
ARP and Telnet
If the unit has no IP address, you can use Address Resolution Protocol (ARP).
To assign a temporary IP address:
1. On a UNIX or Windows-based host, create an entry in the host's ARP table using
the intended IP address and the hardware address of the unit (on the product
label on the bottom of the unit).
arp -s 191.12.3.77 00:20:4a:xx:xx:xx
Note: For the ARP command to work on Windows 95, the ARP table on
the PC must have at least one IP address defined other than its own.
2. If you are using Windows 95, type ARP -A at the DOS command prompt to verify
that there is at least one entry in the ARP table. If the local machine is the only
entry, ping another IP address on your network to build a new entry in the ARP
table; the IP address must be a host other than the machine on which you are
working. Once there is at least one additional entry in the ARP table, use the
following command to ARP an IP address to the unit:
arp -s 191.12.3.77 00-20-4a-xx-xx-xx
3. 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
4. Open a Telnet connection to port 9999, and press Enter within five seconds to
go into Setup Mode. If you wait longer than five seconds, the unit reboots.
telnet 191.12.3.77 9999
Note: The IP address you just set is temporary and reverts to the default value
when the unit’s power is reset, unless you configure the unit with a static IP
address and store the changes permanently.
