6.4 Assigning the Initial IP Address
Before proceeding, read this entire section.
Ensure that the DX4020 has power and the
Ethernet Network RJ-45 connection is in
place.
Ensure that the PC used to configure the
DX4020 and the DX4020 itself are on the
same gateway (the device connecting the
LAN to the WAN).
Use Telnet to configure the DX4020’s
communications parameters.
When the DX4020 is configured and has
an IP address, you can use Telnet from
anywhere on the network to change the
configuration parameters.
6.4.1 ARP Command Overview
When you have received a valid IP address from the
network administrator, open the DOS prompt (from
Windows) on any PC connected to the network you
are using.
Temporarily assign the DX4020 IP address to its
hardware address on the Host PC using ARP. During
installation, the ARP is installed by default in the
\WINDOWS directory (Windows 98, Windows
Millennium) or the \WINNT directory (Windows 2000
and Windows XP).
At the DOS prompt (usually C:\windows) use the
command syntax shown in Figure 15.

1 xxx.xxx.xxx.xxx (The IP address assigned to the
DX4020 by the network administrator.)
2 zz-zz-zz-zz-zz-zz (The MAC hardware address
on the DX4020 XPort NIM.)
Section 6.4.2 describes how to assign an IP address to a
DX4020 NIM using the ARP command.
6.4.2 Using the ARP Command
1. From the Start Menu, select Start Æ Run to open
a DOS window.
2. At the Run dialog box, type COMMAND and
click [OK].
A DOS window appears.
1. At the DOS command line, type arp –s
172.17.10.70 00-20-4a-12-04-0e and press [Enter].
3. In this example, 172.17.10.70 is the IP address
from the network administrator and 00-20-4a-12-
04-0e is the DX4020 MAC hardware address.
The system does not indicate that the
operation was properly performed. The
absence of an error message indicates the
function is correct.
4. Verify that the IP address was correctly entered in
the ARP table by typing arp -g and pressing
[Enter].
The following message appears.
This message shows the Internet address (IP address)
and the corresponding physical address (MAC
hardware address). The third line in the table shows the
arp MAC address of 00-20-4a-51-19-8c is temporarily
linked to IP address 172.17.10.70.
The network uses this table to identify devices and
route signals. The number of devices and other types,
such as dynamic, depends on the network and the
number and type of devices the PC communicated
with. You must identify the MAC address of the device
you are installing and verify it has an IP address linked
to it.
