Alternative Ways to Assign an IP Address
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)
method from UNIX and Windows-based systems to assign a temporary IP address.
To assign a temporary IP address:
Note:
value when the unit’s power is reset, unless you configure the unit with a
static IP address and store the changes permanently.
1. On a UNIX or Windows-based host, create an entry in the host's ARP table
2. If you are using Windows 95, type ARP -A at the DOS command prompt to
3. Open a Telnet connection to port 1. The connection fails quickly, but the unit
4. Open a Telnet connection to port 9999, and press Enter within five seconds
The IP address you just set is temporary and reverts to the default
using the intended IP address and the hardware address of the unit (on the
product label on the bottom of the unit).
Note:
on the PC must have at least one IP address defined other than its
own.
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:
temporarily changes its IP address to the one designated in this step.
to go into Setup Mode. If you wait longer than five seconds, the unit reboots.
For the ARP command to work on Windows 95, the ARP table
arp -s 191.12.3.77 00:20:4a:xx:xx:xx
arp -s 191.12.3.77 00-20-4a-xx-xx-xx
telnet 191.12.3.77 9999
telnet 191.12.3.77 1
