Auto mode
In this mode, the machine will scan the network for a DHCP server, if it can find one, and if the DHCP server is configured to allocate an IP address
to the machine, then the IP address supplied by the DHCP server will be used. If no DHCP server is available, then the machine will scan for a
BOOTP server. If a BOOTP server is available, and it is configured correctly, the machine will take its IP address from the BOOTP server. If a
BOOTP server is not available, the machine will scan for a RARP server. If a RARP server also does not answer, the IP Address is set using the
APIPA protocol. After the machine is initially powered ON, it may take a few minutes for the machine to scan the network for a server.
2
Static mode
In this mode the machine’s IP address must be manually assigned. Once entered the IP address is locked to the assigned address.
3
RARP mode
The Brother print server’s IP address can be configured using the Reverse ARP (RARP) facility on your host computer. This is done by editing
the
/etc/ethers
file (if this file does not exist, you can create it) with an entry similar to the following:
00:80:77:31:01:07 BRN008077310107
Where the first entry is the Ethernet address of the print server and the second entry is the name of the print server (the name must be the same
as the one you put in the
/etc/hosts
file).
If the RARP daemon is not already running, start it (depending on the system the command can be
rarpd
,
rarpd -a
,
in.rarpd -a
or
something else; type
man rarpd
or refer to your system documentation for additional information). To verify that the RARP daemon is running
on a Berkeley UNIX
®
based system, type the following command:
ps -ax | grep -v grep | grep rarpd
For AT&T UNIX
®
-based systems, type:
ps -ef | grep -v grep | grep rarpd
The Brother print server will get the IP address from the RARP daemon when the printer is powered on.
4
BOOTP mode
BOOTP is an alternative to RARP that has the advantage of allowing configuration of the subnet mask and gateway. In order to use BOOTP to
configure the IP address make sure that BOOTP is installed and running on your host computer (it should appear in the
/etc/services
file on
your host as a real service; type
man bootpd
or refer to your system documentation for information). BOOTP is usually started up via the
/etc/inetd.conf
file, so you may need to enable it by removing the “#” in front of the bootp entry in that file. For example, a typical bootp entry
in the /etc/inetd.conf file would be:
#bootp dgram udp wait /usr/etc/bootpd bootpd -i
Depending on the system, this entry might be called “bootps” instead of “bootp”.
Note
In order to enable BOOTP, simply use an editor to delete the “#” (if there is no “#”, then BOOTP is already enabled). Then edit the BOOTP
configuration file (usually
/etc/bootptab
) and enter the name, network type (1 for Ethernet), Ethernet address and the IP address, subnet mask
and gateway of the print server. Unfortunately, the exact format for doing this is not standardized, so you will need to refer to your system
documentation to determine how to enter this information (many UNIX
®
systems also have template examples in the bootptab file that you can
use for reference). Some examples of typical
/etc/bootptab
entries include:
BRN008077310107 1 00:80:77:31:01:07 192.168.1.2
and:
BRN008077310107:ht=ethernet:ha=008077310107:\
ip=192.168.1.2:
Certain BOOTP host software implementations will not respond to BOOTP requests if you have not included a download filename in the
configuration file. If this is the case, simply create a null file on the host and specify the name of this file and its path in the configuration file.
As with RARP, the print server will load its IP address from the BOOTP server when the printer is powered on.
5
DHCP mode
Dynamic Host Configuration Protocol (DHCP) is one of several automated mechanisms for IP address allocation. If you have a DHCP server in
your network (typically a UNIX
®
, Windows
®
2000/XP, Windows Vista
®
network) the print server will automatically obtain its IP address from a
DHCP server and register its name with any RFC 1001 and 1002 compliant dynamic name services.
Note
• If you do not want your print server configured via DHCP, BOOTP or RARP, you must set the BOOT Method to static so that the print server has
a static IP address. This will prevent the print server from trying to obtain an IP address from any of these systems. To change the BOOT Method,
use the machine’s control panel
LAN
menu, BRAdmin applications, Remote Setup or Web Based Management (web browser).
• On smaller networks, the DHCP server may be the router.
