arp -s ipaddress ethernetaddress
Where ethernetaddress is the Ethernet address (MAC address)
of the print server and ipaddress is the IP address of the print
server. For example:
Windows® Systems
Windows ® Systems require the colon ":" character between each
digit of the Ethernet address.
arp -s 192.189.207.2 00:80:77:31:01:07
Unix Systems
Typically, Unix systems require the hash "-" character between each
digit of the Ethernet address.
arp -s 192.189.207.2 00-80-77-31-01-07
To configure the print server and to verify the connection, enter
the following command
ping ipaddress where
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 (if your printer has an LCD panel) or factory reset the print
server (which will then allow you to use the ARP command again).
