Using ARP to configure the IP address
A
If you are unable to use the BRAdmin application and your network does not use a DHCP server, you can
also use the ARP command. The ARP command is available on Windows
®
systems that have TCP/IP
installed as well as UNIX
®
systems. To use ARP enter the following command at the command prompt:
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
®
Windows
®
systems require the dash “-” character between each digit of the MAC Address (Ethernet
Address).
arp -s 192.168.1.2 00-80-77-31-01-07
UNIX
®
/Linux
®
Typically, UNIX
®
and Linux
®
systems require the colon “:” character between each digit of the MAC
Address (Ethernet Address).
arp -s 192.168.1.2 00:80:77:31:01:07
Note
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 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
.
