Setting the IP Address
On a UNIX host, create an entry in the host's ARP table and substitute the intended IP ad-
dress and the hardware address of the EPS, then ping the EPS. This process typically re-
quires superuser privileges.
# arp -s 192.0.1.228 00-80-a3-xx-xx-xx
% ping 192.0.1.228
In order for the ARP command to work on Windows, the ARP table on the PC must have
at least one IP address defined other than its own. If the ARP table is empty, the command
will return an error message. Type ARP -A at the DOS command prompt to verify that
there is at least one entry in the ARP table.
C:\ ARP -S 192.0.1.228 00-80-A3-XX-XX-XX
C:\ PING 192.0.1.228
There should be replies from the IP address if the ARP command

worked.
When the EPS receives the ping packet, it will notice that its IP address is not set and will
send out broadcasts to see if another node is using the specified address. If no duplicate is
found, the EPS will use the IP address and will respond to the ping packet.
The EPS will not save the learned IP address permanently; this procedure is intended as a
temporary measure to enable EZWebCon to communicate with the EPS, or allow an ad-
ministrator to Telnet into the EPS. Once logged in, the administrator can enter the Change
IPaddress command to make the address permanent.
% telnet 192.0.1.228

Any host wishing to access the EPS will have to be told the EPS's IP address. This is typ-
ically configured in the unix file /etc/hosts or via a nameserver. Refer to the host's docu-
mentation for additional information.
