Introduction
1 - Introduction
The Lantronix multi-port Fast Ethernet Print Servers (EPS2-100 and EPS4-100) are multiprotocol
print servers that provide shared network access to printers for a variety of network protocols and
operating systems. The EPS2-100 and EPS4-100 support the AppleTalk (EtherTalk), LAN
Manager, Local Area Transport (LAT), IPX (NetWare), and TCP/IP protocols. Both servers queue
multiple pending jobs and service those jobs in the order that they are received from the hosts.
NOTE: In this manual, both the EPS2-100 and the EPS4-100 servers will be
referred to as the EPS or as the Server unless a distinction needs to be
made between the models.

help.
2 - 4
Installation
1. Connect at least one printer to the EPS using an available serial or parallel port.
2. If desired, connect a terminal to port 1 (the console port) to receive diagnostic and initial
configuration messages.
3. Connect the EPS to the 10/100BASE-T network.
NOTE: The default serial port settings are 9600 baud, 8 bit characters, and no parity.
4. Attach one end of the power cable to the EPS; plug the other end into an electrical outlet.
Power will come on automatically.
5. Allow 45 seconds for the unit to fully boot. The OK LED should be lit to show the unit is
functioning properly.
If you have connected a 10BASE-T cable to the Server, the Link LED should be solid
green. If you have connected a 100BASE-T cable, The Link and 100MBit LEDs should
both be solid green. If not, check your network connection.
6. Print a Test page by pressing the Test/Reset button.
NOTE: If the Power LED does not light or the Test page does not print, refer to
Appendix I, Troubleshooting.
7. Install EZWebCon on your 32-bit Windows PC to configure your Server. The EZWebCon
software is located on the CD-ROM. See EZWebCon Configuration on page 3-2 for more
information.

Getting Started
3 - Getting Started
It is important to consider the following points before logging into and configuring the EPS:
The EPS IP address must be configured before any TCP/IP functionality is available.
(See Setting the IP Address on page 4-2.)
There are two important passwords on the EPS: the privileged password and the login
password.
Changing any server, service, or port setting requires privileged user status. The default privileged password is system.
The login password is required for remote console logins.
The default login password is access.
NOTE: If you would like to change either the privileged or login password,
either use EZWebCon or refer to the Print Server Reference Manual
located on the CD-ROM.

Getting Started
3.1 EZWebCon Configuration
The EZWebCon configuration software is the recommended way to configure the EPS.
EZWebCon is a graphical user interface that guides first time users through the initial
configuration process and allows experienced users to update and change any configurable
parameters. There are two important things to note about EZWebCon:
Your Server must have an IP address before EZWebCon can log into it for configura-
tion purposes. See Setting the IP Address on page 4-2 for instructions.
EZWebCon requires a Java Virtual Machine (JVM) on the client. Lantronix provides
JVM installers for Solaris and 32-bit Windows users, as well as source code and
instructions for compiling it for use on other systems.
The EZWebCon software is located on the distribution CD-ROM. All instructions for installing
EZWebCon are provided in the README file. For assistance once EZWebCon is running, refer to
the EZWebCon on-line help.
NOTE: EZWebCon is also available from the Lantronix FTP and BBS servers.
See Appendix D for more information about logging into the FTP and
BBS servers.

Getting Started
3.2 Incoming Logins
Incoming logins made via EZWebCon can be used to configure the server. Incoming LAT and
TCP/IP logins can also be used.
Incoming Telnet is enabled by default to allow TCP/IP connections. To change this setting, use
the Define Server Incoming command described in the Command Reference chapter of the Print
Server Reference Manual located on CD-ROM.
Incoming logins do not prompt for a login password; therefore, you may wish to disable them. If
it is undesirable to disable incoming logins, the Server can be configured to prompt for a
password with the Define Server Incoming Password Enabled command.
3.3 Services
With few exceptions, a service must be created before print queues can be configured on the EPS.
A service is a resource accessible to network hosts. A Lantronix service is also known as a remote
printer name or remote queue name on many operating systems.
The EPS
xxxxxx represents the last six numbers of the unit’s Ethernet address and yy is the port name, for
example EPS_xxxxxx_S1 (serial port) or EPS_xxxxxx_P1 (parallel port).
offers a default service on each port. The service names are EPS_xxxxxx_yy where
NOTE: The default service names are based on the server name; therefore the
server name must be no more than 13 characters.
3 - 3
Getting Started
The default services on the serial ports have the TCP/IP, NetWare, LAN Manager, and AppleTalk
protocols enabled. Parallel port services have TCP/IP, NetWare, and LAN Manager enabled. LAT
is disabled by default on all services provided by the Server
because many network managers
object to the frequent LAT service announcements. AppleTalk is disabled on parallel port services
because AppleTalk requires Bitronics mode, which is disabled by default.
If you need to modify a default service, use EZWebCon or see the Server Configuration chapter of
the Print Server Reference Manual located on the CD-ROM.

TCP/IP Configuration
4 - TCP/IP Configuration
The EZWebCon configuration software is the easiest way to configure the EPS. The following
sections cover IP address configuration and print configuration methods for TCP/IP hosts.
NOTE: The Server needs an IP address before you can use EZWebCon. See
page 4-2 for instructions.
The EPS provides two major methods of printing via TCP/IP: Berkeley remote LPR and RTEL
host software.
Neither Windows for Workgroups nor Windows 95 support LPR directly; however, there are third
party solutions available. For more information about recommended peer-to-peer printing
solutions, see the Lantronix Windows 95 FAQ on the CD-ROM or the Lantronix web site.

TCP/IP Configuration
4.1 Setting the IP Address
The EPS IP address must be configured before any TCP/IP functionality is available.
To set the IP address, use one of the following methods: EZWebCon; a directed Ping packet; a
DHCP, BOOTP, or RARP reply; or commands entered at the command line (Local>) interface.
4.1.1 Using EZWebCon
The EPS must have an IP address before you can log into it using EZWebCon. To assign the IP
address from EZWebCon:
1. Start EZWebCon. Instructions for installing, running, and using EZWebCon can be found
on the distribution CD-ROM.
2. Click on the Lantronix logo menu in the bottom left corner of the EZWebCon window,
then select Assign IP Address to Server.
3. Fill in the following information:
A. The last three bytes of the EPS’s hardware address. The hardware address is printed
on the bottom of the Server.
B. The desired IP address.
C. The subnet, if you wish to use a subnet other than the default.
4 - 2
TCP/IP Configuration
D. The IP address of the TFTP server you wish to use, if desired.
4. Click OK.
5. Cycle power on the server. EZWebCon will let you know whether the configuration was
successful.
4.1.2 Using a Directed Ping Packet
The ARP/ping method is available under UNIX, Windows 95, and Windows NT. If the EPS has
no IP address, it will set its address from the first directed IP packet it receives.
NOTE: The ARP/ping method only works during the first two minutes of EPS
operation. After two minutes, an alternate method must be used or the
EPS must be rebooted.
On a UNIX host, create an entry in the host’s ARP table and substitute the intended IP address
and the hardware address of the server, then ping the server. This process typically requires
superuser privileges.
# arp -s 192.0.1.228 00:80:a3:xx:xx:xx
% ping 192.0.1.228
4 - 3
TCP/IP Configuration
In order for the ARP command to work on Windows, the ARP table on the PC must have at least
one IP address defined other than its own. If the ARP table is empty, the command will return an
error message. Type ARP -A at the DOS command prompt to verify that there is at least one entry
in the ARP table.
If there is no other entry beside the local machine, ping another IP machine on your network to
build the ARP table. This has to be a host other than the machine that you're working on. Once
there is at least one entry in the ARP table, use the following commands to ARP the IP address to
the EPS and make the EPS acknowledge the IP assignment.
C:\ ARP -S 192.0.1.228 00-80-A3-XX-XXXX
C:\ PING 192.0.1.228
NOTE: There should be replies from the IP address if the ARP command
worked.
When the EPS receives the ping packet, it will notice that its IP address is not set and will send out
broadcasts to see if another node is using the specified address. If no duplicate is found, the server
will use the IP address and will respond to the ping packet.
The EPS will not save the learned IP address permanently; this procedure is intended as a
temporary measure to enable EZWebCon to communicate with the server, or allow an

administrator to Telnet into the EPS. Once logged in, the administrator can enter the Change
IPaddress command to make the address permanent.
% telnet 192.0.1.228

Local> SET PRIVILEGED
Password> system (not echoed)
Local>> DEFINE IPADDRESS 192.0.1.228
Any host wishing to access the EPS will have to be told the EPS’s IP address. This is typically
configured in the unix file /etc/hosts or via a nameserver. Refer to the host’s documentation for
additional information.
4 - 5
TCP/IP Configuration
4.1.3 Using a DHCP, BOOTP, or RARP Reply
At boot time a host-based DHCP, BOOTP, or RARP server can respond to an EPS request for an
available IP address. For information about configuring the DHCP, BOOTP, or RARP server, see
your host documentation.
4.1.4 Using the Command Line Interface
1. Connect to the serial port (Port 1) using a terminal emulation program. The serial settings
should be 9600 baud, 8 bits, 1 stop bit, no parity.
2. Become the privileged user and enter the new IP address.
Local> SET PRIVILEGED
Password> system (not echoed)
Local>> DEFINE SERVER IPADDRESS 192.0.1.201

TCP/IP Configuration
4.2 Notes About LPR
There are four important things to note about the LPR printing method:
1. Because of the way the LPR protocol is typically implemented on the host, the processing
options and banner page are sent after the job data itself. The EPS will print a banner
page at the end of a job, and cannot support most of the LPR options. If it is necessary
to have the banner page at the beginning of the printout, install and use the RTEL software. If banners are not needed, they can be disabled.
2. The EPS cannot print multiple copies of the print job when using the -#n lpr option.
3. If two print queues on the host refer to two services on the same EPS, they must use separate spooling directories.
4. No special purpose input or output filters can be used when printing via LPR. If this functionality is necessary, use the named pipe interface program in the RTEL print queue configuration software.
