							CHAPTER 12 TCP/IP CONFIGURATION
12-9
Using BOOTP to Configure the IP
Address
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.
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:
BRN_310107 1  00:80:77:31:01:07 192.189.207.3
and:
BRN_310107:ht=ethernet:ha=008077310107:\
ip=192.189.207.3:
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.

Configuring the IP Address with DEC NCP
or BRCONFIG
Users of DEC and Novell networks have additional alternatives for configuring the
IP address of Brother print servers by using the remote console facility. On VMS
systems, you will need to have DECNET running in order to use the remote console.
The procedure of DEC Network is as follows:
Connect to the remote console, if you are using the remote console with VMS or
LTRIX, you will need to know the circuit ID *QNA-0 for Q-BUS systems, SVA-0
for DEC workstations, UNA-0 for UNIBUS systems, BNA-0 for BI systems, and
MNA-0 for XMI systems; you can get the circuit ID by executing the VMS NCP
command SHOW KNOWN CIRCUITS) and the Ethernet address of the print server
(which you can get either from the label on the print server or via the printer
configuration page).
To do this on a printer that has an LCD panel: take the printer off-line by pressing the
SEL button, press and hold down the SHIFT button then press the UP arrow button
until PRINT CONFIG is displayed, press the SET button. The printer will then print
out a configuration sheet, the sheet labeled Print Configuration contains all Print
Server configuration information. Put the printer back on-line again by pressing the
SEL button.
For internal Print Servers that are connected to a Brother printer which do not have
an LCD panel, refer to your printer user guide for instructions on how to print out a
configuration page.
Brothers external interfaces, which connect to the parallel interface, have a black
button recessed into the rear of the unit. Press this button to print out a configuration
sheet.
On VMS systems, the connection is made as shown in the following example:
$ MCR NCP
NCP>CONNECT VIA QNA-0 PHY ADD 00-80-77-31-01-07
On ULTRIX systems, you would execute commands similar to the following
example:
# addnode BR -c qna-0 -h 00-80-77-31-01-07
# ccr BR 
						

							CHAPTER 12 TCP/IP CONFIGURATION
12-11
On a NetWare networks, you can use the BRCONFIG utility which are included with
every print server.
If you are using the remote console, you will get the message Console connected
(VMS) or Connection established (BRCONFIG) or Remote console reserved
(ULTRIX). Press RETURN and enter the default password access in response to
the # prompt (it will not echo).
You will be prompted for a user name. Enter anything in response to this prompt.
You will then get the Local> prompt. Type SET IP ADDRESS ipaddress, where
ipaddress is the desired IP address you wish to assign to the print server (check with
your network manager for the IP address to use). For example:
Local> SET IP ADDRESS 192.189.207.3
You will now need to set the subnet mask by typing SET IP SUBNET subnet mask,
where subnet mask is the desired subnet mask you wish to assign to the print server
(check with your network manager for the subnet mask to use). For example:
Local> SET IP SUBNET 255.255.255.0
If you do not have any subnets, use one of the following default subnet masks:
255.255.255.0  for class C networks
255.255.0.0  for class B networks
255.0.0.0  for class A networks 
						

							CHAPTER 12 TCP/IP CONFIGURATION
12-12
The leftmost group of digits in your IP address can identify the type of network you
have. The value of this group ranges from 192 through 255 for Class C networks
(e.g., 192.189.207.3), 128 through 191 for Class B networks (e.g.,128.10.1.30), and 1
through 127 for Class A networks (e.g., 13.27.7.1).
If you have a gateway (router), enter its address with the command SET IP ROUTER
routeraddress, where routeraddress is the desired IP address of the gateway you wish
to assign to the print server. For example:
Local> SET IP ROUTER 192.189.207.1
To verify that you have entered the IP information correctly, type SHOW IP.
Type EXIT or CTR-D (i.e., hold down the control key and type D) to end the
remote console session. 
						

							CHAPTER 12 TCP/IP CONFIGURATION
12-13
Changing the IP Address settings with
the TELNET Console
You can also use the TELNET command to change the IP address.
Using TELNET is effective way, when you change the IP address. But a valid IP
address must already be programmed into the print server.
If you are using the TELNET, you will be expected to enter the password of the print
server. Press RETURN and enter the default password of access in response to the
# prompt (it will not echo).
You will be prompted for a user name. Enter anything in response to this prompt.
You will then get the Local> prompt. Type SET IP ADDRESS ipaddress, where
ipaddress is the desired IP address you wish to assign to the print server (check with
your network manager for the IP address to use). For example:
Local> SET IP ADDRESS 192.189.207.3
You will now need to set the subnet mask by typing SET IP SUBNET subnet mask,
where subnet mask is the desired subnet mask you wish to assign to the print server
(check with your network manager for the subnet mask to use). For example:
Local> SET IP SUBNET 255.255.255.0
If you do not have any subnets, use one of the following default subnet masks:
255.255.255.0  for class C networks
255.255.0.0  for class B networks
255.0.0.0  for class A networks
The leftmost group of digits in your IP address can identify the type of network you
have. The value of this group ranges from 192 through 255 for Class C networks
(e.g., 192.189.207.3), 128 through 191 for Class B networks (e.g.,128.10.1.30), and 1
through 127 for Class A networks (e.g., 13.27.7.1).
If you have a gateway (router), enter its address with the command SET IP ROUTER
routeraddress, where routeraddress is the desired IP address of the gateway you wish
to assign to the print server. For example:
Local> SET IP ROUTER 192.189.207.1
To verify that you have entered the IP information correctly, type SHOW IP.
Type EXIT or CTR-D (i.e., hold down the control key and type D) to end the
remote console session.

CHAPTER THIRTEEN
Troubleshooting
Overview
This chapter describes procedures for troubleshooting problems you may encounter
with a Brother Print Server, it is divided into the following sections:
1. Installation Problems
2. Intermittent Problems
3. Protocol-Specific Troubleshooting 
						

							CHAPTER 13 TROUBLESHOOTING
13-2
Installation problems
If you cannot print over the network, check the following:
1.
 Make sure that the printer is powered on, is on-line and ready to print.
Verify that the printer and the configuration are good by printing the
configuration page. Refer to the Quick Setup Guide for information on how
to print the configuration page on your print server. If the test fails, check:
a.
 If the Alarm LED on the printer front panel is ON or blinking and all of
the LEDs on the back panel - near the UTP (Ethernet) connector - are
OFF, or the Orange (F) LED is blinking, then the network firmware
settings may be corrupted. (NC-2000 series print server users, please
consult the troubleshooting section of the NC-2000 series user guide).
b.
 In this event, try to restore the factory default settings of the print server
by pressing the TEST switch on the back panel of the printer for longer
than 5 seconds. Once you have done that, switch the printer off and then
on again, and try to print out the configuration page.
2.
 If the configuration page prints but you cannot print documents, try the
following
If none of the following steps are successful, there is almost certainly a hardware or
network problem! 
						

							CHAPTER 13 TROUBLESHOOTING
13-3
a. If you are using TCP/IP:
Try pinging the print server from  the host operating system command
prompt with the command:
ping ipaddress
Where ipaddress is the print server IP address (note that in some
instances it can take up to two minutes for the print server load its IP
address (after setting the IP address). If a successful response is
received, then proceed to the UNIX, TCP/IP Windows NT/LAN Server,
Windows98/95/Me Peer to Peer (LPR), Internet Printing or Web
Browser troubleshooting section. Otherwise, proceed to step 3, and then
go to TCP/IP Trouble shooting section.
b. If you are using Novell system:
Verify that the print server can be seen on the network. To do this, login
as the SUPERVISOR (not as someone with supervisor privileges) or
ADMIN (for Netware 4 or later servers), go into PCONSOLE or
NWADMIN, select PRINT SERVER INFORMATION, and select the
name of the print server (make sure that you have entered the print
server name). If you can see Print Server Status and Control in the
menu, then the Brother print server is visible to the network, proceed to
the Novel NetWare Installation Troubleshooting Section. Otherwise, go
to step 3.
c. If you are running AppleTalk for Macintosh:
Make sure that you can see the print server name under the LaserWriter
8 icon in the Chooser. If it is visible, then the connection is good, so
proceed to the AppleTalk for Macintosh Section. Otherwise, go to
step 3. 
						

							CHAPTER 13 TROUBLESHOOTING
13-4
3.
 If you cannot make any of the connections in step 2, check the following:
a.
 Make sure the printer is powered on and on-line.
b.
 Verify that the cabling, network connection, and print out a
configuration page in the Network STATISTICS information to see if
bytes are being transmitted and received.
c.
 Check to see if there is any LED activity.
The NC-3000/4000 series print servers have three LEDs. These can be used
to diagnose problems.
·
 L- LED (green): Link activity
This LED is on if there is a valid connection to the network (either
10BaseT or 100BaseTX). It is off if no network is detected.
·
 F-LED (orange): Fast Ethernet
This LED will be on if the print server is connected to a 100BaseTX
Fast Ethernet network. It is off if the print server is connected to a
10BaseT network.
·
 A-LED (green): Transmission Activity
This LED will blink synchronized to the transmission or receive status.
NC-2000 series print servers have a different set of LEDs. For further
information refer to the NC-2000 series network user guide.
4.
 If you are using a repeater or hub, make sure that SQE (heartbeat) is turned
off at the hub (if applicable). Also, if you have a hub or multi-port repeater,
verify that the hub or repeater port is good by trying the print server on a
different port or on the other hub or multi-port repeater.
5.
 If you have a bridge or router located between the print server and host
computer, make sure that the device is set up to allow the print server to
send and receive data from the host. For example, a bridge can be set up to
only allow certain types of Ethernet addresses to pass through (a process
known as filtering); therefore, such a bridge must be configured to allow
Brother print server addresses. Likewise, a router can be set up to pass only
certain protocols, so be sure that the desired protocol can be passed through
to the print server.
6.
 If the job exits the queue but does not print, make sure that you are not
trying to print a text job to a PostScript printer. If you have a printer that is
capable of automatic language switching, make sure that the printer is not
forced into PostScript mode.
