Unix/Linux Systems
Typically, Unix systems require the colon ":" character between
each digit of the Ethernet address.
arp -s 192.189.207.2 00:80:77:31:01:07
You must be on the same Ethernet segment (that is, there
cannot be a router between the Print/Fax 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/
Fax 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/Fax
server using the ARP command, you cannot use the ARP
command again to change the address. The Print/Fax server
will ignore any attempts to do this. If you wish to change the
IP address again, use a Web Browser, the machine's control
panel or factory reset the Print/Fax server (which will then
allow you to use the ARP command again).
To configure the Print/Fax server and to verify the connection,
enter the following command ping ipaddress where
ipaddress is the IP address of the Print/Fax server. For
example, ping 192.189.207.2.
