You must be on the same Ethernet segment (that is, there cannot
be a router between the print server and operating system) to use
the arp -s command.
If there is a router, you may use BOOTP or other methods
described in this chapter to enter the IP address.
If your Administrator has configured the system to deliver IP
addresses using BOOTP, DHCP or RARP your Brother print
server can receive an IP address from any one of these IP
address allocation systems. In which case, you will not need to
use the ARP command. The ARP command only works once. For
security reasons, once you have successfully configured the IP
address of a Brother print server using the ARP command, you
cannot use the ARP command again to change the address. The
print server will ignore any attempts to do this. If you wish to
change the IP address again, use a Web Browser, TELNET
(using the SET IP ADDRESS command) the printer's control
panel or factory reset the print server (which will then allow you to
use the ARP command again).
To configure the print server and to verify the connection,
enter the following command ping ipaddress where
ipaddress is the IP address of the print server. For
example, ping 192.189.207.2.
