Types of network connections 1
Wired network connection example 1
Peer-to-Peer printing using TCP/IP 1
In a Peer-to-Peer environment, each computer directly sends and receives data to each device. There is no
central server controlling file access or machine sharing.
1 Router
2 Network machine (your machine)
In a smaller network of 2 or 3 computers, we recommend the Peer-to-Peer printing method as it is easier
to configure than the Network Shared printing method. See Network Shared printing uu page 1.
Each computer must use the TCP/IP Protocol.
The Brother machine needs an appropriate IP address configuration.
If you are using a router, the Gateway address must be configured on the computers and the Brother
machine.
Network Shared printing 1
In a Network Shared environment, each computer sends data via a centrally controlled computer. This type
of computer is often called a “Server” or a “Print Server”. Its job is to control the printing of all print jobs.

1
Protocols 1
TCP/IP protocols and functions 1
Protocols are the standardized sets of rules for transmitting data on a network. Protocols allow users to gain
access to network connected resources.
The print server used on the Brother machine supports the TCP/IP (Transmission Control Protocol/Internet
Protocol) protocol.
TCP/IP is the most popular set of protocols used for communication such as Internet and E-mail. This protocol
can be used in almost all operating systems such as Windows®, Windows Server®, Mac OS X and Linux®.
The following TCP/IP protocols are available on the Brother machine.
Note
• You can configure the protocol settings by using the HTTP interface (web browser). (See the Network
User's Guide.)
• To find what protocols your Brother machine supports, see the Network User's Guide.
DHCP/BOOTP/RARP 1
By using the DHCP/BOOTP/RARP protocols, the IP address can be automatically configured.
Note
To use the DHCP/BOOTP/RARP protocols, please contact your network administrator.
APIPA 1
If you do not assign an IP address manually (using the control panel (for LCD models) of the machine or the
BRAdmin software) or automatically (using a DHCP/BOOTP/RARP server), the Automatic Private IP
Addressing (APIPA) protocol will automatically assign an IP address from the range 169.254.1.0 to
169.254.254.255.
ARP 1
Address Resolution Protocol performs mapping of an IP address to MAC address in a TCP/IP network.
DNS client 1
The Brother print server supports the Domain Name System (DNS) client function. This function allows the
print server to communicate with other devices by using its DNS name.
NetBIOS name resolution 1
Network Basic Input/Output System name resolution enables you to obtain the IP address of the other device
using its NetBIOS name during the network connection.

Types of network connections and protocols
4
1
WINS 1
Windows®Internet Name Service is an information providing service for the NetBIOS name resolution by
consolidating an IP address and a NetBIOS name that is in the local network.
LPR/LPD 1
Commonly used printing protocols on a TCP/IP network.
Custom Raw Port (Default is Port 9100) 1
Another commonly used printing protocol on a TCP/IP network. It enables interactive data transmission.
mDNS 1
mDNS allows the Brother print server to automatically configure itself to work in a Mac OS X Simple Network
Configured system.
SNMP 1
The Simple Network Management Protocol (SNMP) is used to manage network devices including computers,
routers and Brother network ready machines. The Brother print server supports SNMPv1 and SNMPv2.
LLMNR 1
The Link-Local Multicast Name Resolution protocol (LLMNR) resolves the names of neighboring computers,
if the network does not have a Domain Name System (DNS) server. The LLMNR Responder function works
in both the IPv4 or IPv6 environment when using a computer that has the LLMNR Sender function such as
Windows Vista®and Windows®7.
Web Services 1
The Web Services protocol enables Windows Vista®or Windows®7 users to install the drivers used for
printing and scanning by right-clicking the machine icon from the Network folder. (See Installing drivers used
for printing and scanning via Web Services (Windows Vista®and Windows®7) uu page 11.) For details
about scanning using Web Services, see the Software User's Guide. The Web Services also lets you check
the current status of the machine from your computer.

IP addresses, subnet masks and gateways 2
To use the machine in a networked TCP/IP environment, you need to configure its IP address and subnet
mask. The IP address you assign to the print server must be on the same logical network as your host
computers. If it is not, you must properly configure the subnet mask and the gateway address.
IP address 2
An IP address is a series of numbers that identifies each device connected to a network. An IP address
consists of four numbers separated by dots. Each number is between 0 and 255.
Example: In a small network, you would normally change the final number.
•192.168.1.1
•192.168.1.2
•192.168.1.3
How the IP address is assigned to your print server: 2
If you have a DHCP/BOOTP/RARP server in your network the print server will automatically obtain its IP
address from that server.
Note
On smaller networks, the DHCP server may also be the Router.
For more information on DHCP, BOOTP and RARP, see:
Using DHCP to configure the IP address uu page 14.
Using BOOTP to configure the IP address uu page 15.
Using RARP to configure the IP address uu page 14.
If you do not have a DHCP/BOOTP/RARP server, the Automatic Private IP Addressing (APIPA) protocol will
automatically assign an IP address from the range 169.254.1.0 to 169.254.254.255. For more information on
APIPA, see Using APIPA to configure the IP address uu page 15.

Subnet mask 2
Subnet masks restrict network communication.
Example: Computer 1 can talk to Computer 2
•Computer1
IP Address: 192.168. 1. 2
Subnet Mask: 255.255.255.000
•Computer2
IP Address: 192.168. 1. 3
Subnet Mask: 255.255.255.000
Where the 0 is in the Subnet mask, there is no limit to communication at this part of the address. What this
means in the above example is, we can communicate with any device that has an IP address that begins with
192.168.1.x. (where x. are numbers between 0 and 255).
Gateway (and router) 2
A gateway is a network point that acts as an entrance to another network and sends data transmitted via the
network to an exact destination. The router knows where to direct data that arrives at the gateway. If a
destination is located on an external network, the router transmits data to the external network. If your network
communicates with other networks, you may need to configure the Gateway IP address. If you do not know
the Gateway IP address then contact your Network Administrator.

Specifying your network 3
SSID (Service Set Identifier) and channels 3
You need to configure the SSID and a channel to specify the wireless network you want to connect to.
SSID
Each wireless network has its own unique network name and it is technically referred to as an SSID or
ESSID (Extended Service Set Identifier). The SSID is a 32-byte or less value and is assigned to the access
point. The wireless network devices you want to associate to the wireless network should match the
access point. The access point and wireless network devices regularly send wireless packets (referred to
as a beacon) which has the SSID information. When your wireless network device receives a beacon, you
can identify the wireless network that is close enough for the radio waves to reach your device.
Channels
Wireless networks use channels. Each wireless channel is on a different frequency. There are up to 14
different channels that can be used when using a wireless network. However, in many countries the
number of channels available are restricted.

Security terms 3
Authentication and encryption 3
Most wireless networks use some kind of security settings. These security settings define the authentication
(how the device identifies itself to the network) and encryption (how the data is encrypted as it is sent on the
network). If you do not correctly specify these options when you are configuring your Brother wireless
machine, it will not be able to connect to the wireless network. Therefore care must be taken when
configuring these options. Please refer to the information in the Network User's Guide to see which
authentication and encryption methods your Brother wireless machine supports.
Authentication and Encryption methods for a personal wireless network 3
A personal wireless network is a small network, for example using your machine in a wireless network at
home, without IEEE 802.1x support.
Authentication methods 3
Open system
Wireless devices are allowed to access the network without any authentication.
Shared key
A secret pre-determined key is shared by all devices that will access the wireless network.
The Brother wireless machine uses the WEP key as the pre-determined key.
WPA-PSK/WPA2-PSK
Enables a Wi-Fi Protected Access Pre-shared key (WPA-PSK/WPA2-PSK), which enables the Brother
wireless machine to associate with access points using TKIP for WPA-PSK or AES for WPA-PSK and
WPA2-PSK (WPA-Personal).
Encryption methods 3
None
No encryption method is used.
WEP
When using WEP (Wired Equivalent Privacy), the data is transmitted and received with a secure key.
TKIP
TKIP (Temporal Key Integrity Protocol) provides per-packet key mixing, a message integrity check and
rekeying mechanism.
AES
AES (Advanced Encryption Standard) is the Wi-Fi®authorized strong encryption standard.

Network key 3
Open system/Shared key with WEP
This key is a 64-bit or 128-bit value that must be entered in an ASCII or hexadecimal format.
• 64 (40) bit ASCII:
Uses 5 text characters. e.g. “WSLAN” (this is case sensitive)
• 64 (40) bit hexadecimal:
Uses 10 digits of hexadecimal data. e.g. “71f2234aba”
• 128 (104) bit ASCII:
Uses 13 text characters. e.g. “Wirelesscomms” (this is case sensitive)
• 128 (104) bit hexadecimal:
Uses 26 digits of hexadecimal data. e.g. “71f2234ab56cd709e5412aa2ba”
WPA-PSK/WPA2-PSK and TKIP or AES
Uses a Pre-Shared Key (PSK) that is 8 or more characters in length, up to a maximum of 63 characters.

Using services A
A service is a resource that can be accessed by computers that wish to print to the Brother print server. The
Brother print server provides the following predefined services (do a SHOW SERVICE command in the
Brother print server remote console to see a list of available services): Enter HELP at the command prompt
for a list of supported commands.
Where “xxxxxxxxxxxx” is your machine’s MAC Address (Ethernet Address).

Other ways to set the IP address (for advanced users and
administrators) A
Using DHCP to configure the IP address A
The Dynamic Host Configuration Protocol (DHCP) is one of several automated mechanisms for IP address
allocation. If you have a DHCP server on your network, the print server will automatically obtain its IP address
from the 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 Network menu (for LCD models), BRAdmin applications, Remote Setup or Web Based Management
(web browser).
Using RARP to configure the IP address A
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 (or BRW008077310107 for a wireless network)
Where the first entry is the MAC Address (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 machine is powered on.

Appendix A
15
A
Using BOOTP to configure the IP address A
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), MAC Address (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: (“BRN” below is “BRW” for a wireless network.)
BRN310107 1 00:80:77:31:01:07 192.168.1.2
and:
BRN310107: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 machine is powered
on.
Using APIPA to configure the IP address A
The Brother print server supports the Automatic Private IP Addressing (APIPA) protocol. With APIPA, DHCP
clients automatically configure an IP address and subnet mask when a DHCP server is not available. The
device chooses it's own IP address in the range 169.254.1.0 through to 169.254.254.255. The subnet mask
is automatically set to 255.255.0.0 and the gateway address is set to 0.0.0.0.
By default, the APIPA protocol is enabled. If you want to disable the APIPA protocol, you can disable it using
control panel of the machine (for LCD models), BRAdmin Light or Web Based Management (web browser).

Appendix A
16
A
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
ping ipaddress
Where ethernetaddress is the MAC Address (Ethernet Address) of the print server and ipaddress is
the IP address of the print server. For example:
Windows®systems
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
ping 192.168.1.2
UNIX/Linux®systems
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
ping 192.168.1.2
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 a Web Based Management
(web browser), TELNET (using the SET IP ADDRESS command) or factory reset the print server (which
will then allow you to use the ARP command again).
