1: Introduction
The Lantronix EPSs (EPS1 and EPS2) are ethernet print servers that provide shared
network access to printers for a variety of network protocols and operating systems. The
print servers support the TCP/IP, IPX (NetWare), Local Area Transport (LAT),
AppleTalk (EtherTalk), and Microsoft LAN Manager protocols. They can queue
multiple pending jobs and service those jobs in the order in which they are received from
hosts.
Note: In this manual, all EPS servers will be referred to as “the EPS” un-
less a distinction needs to be made between models.
The EPS stores its executable software in Flash (rewritable) ROM, meaning that it does
not have to download software from a host each time it boots. Software must only be
downloaded when a new software version becomes available. See Appendix D for more
information.

2: Installation
This chapter describes the various EPS models and shows how to installthem into a basic
network situation.
2.1 EPS1/2 Product Description
The front panel of the EPS has an RJ45 serial connector and either one (EPS1) or two
(EPS2) DB25 parallel connectors. The port names are Port_1 (serial), Port_2 (top
parallel), and Port_3 (bottom parallel, EPS2 only).
The back panel of the EPS has a power connector, an RJ45 Ethernet connector for
10BASE-T, and an AUI Ethernet connector.
The bottom of the EPS has a label noting the unit’s Ethernet address, needed for
configuration, and 4 DIP switches (explained in the Installation section).
The default name of the EPS is EPS_xxxxxx, where xxxxxx denotes the last 6 digits of
its Ethernet address.

2.2 Installing the EPS
The following diagram shows a properly-installed EPS:
To install the EPS, complete the following steps in order. Refer to the numbers in the figure
for help.
1Set the DIP switches on the bottom of the unit. Their functions are explained in Ta-
ble 2-2.
Note: Switches are only checked at power-up. Changing them while the unit
is operating will have no effect.
2Connect at least one printer to the EPS using an available serial or parallel port.
Table 2-2: DIP Switch Functions
Switch Position 1 Position 0 (default)
1Factory NVR: EPS is restored to
factory defaults at power-up. Normal: Saved EPS settings are used at power-up.
2Silent Boot: The EPS does not print
any status information unless it can-
not boot.
Verbose Boot: The EPS prints boot sta-
tus and PostScript-compatible test jobs
to the serial and parallel ports during
the boot sequence. (Recommended for
first-time setup)

3Attach the EPS to the network using a 10BASE-T cable, transceiver, or AUI cable.
The EPS must have one and only one valid Ethernet connection in order to boot
properly. Use switch 4 to set the correct Ethernet connection type. To boot the EPS
without attaching it to the network, attach a terminated MAU to the AUI port or con-
nect the 10BASE-T port to a disabled hub port.
4Attach one end of the power cable to the EPS; plug the other end into an electrical
outlet. Power will come on automatically.
5Allow 45 seconds for the EPS to fully boot.
❍It will run through a set of power-up diagnostics for approximately 12 seconds.
The 4 LEDs will show varying patterns corresponding to the test being run.
❍It will try to obtain configuration information via DHCP, BOOTP, and RARP.
This step could last approximately 15 seconds if no hosts answer the requests.
The OK LED will blinkapproximately 3 times per second, and the NETWORK
LED will blink occasionally as network requests are transmitted.
❍It will determine if the code in its Flash is valid. If so, it will load the code and
begin normal execution. If not, the EPS will have to download software. See
Appendix D for more information.
6If you have set DIP switch 2 to Verbose (the default), check the status page that
prints when the unit boots.
Note: If the Test page or status page does not print, refer to Appendix B.

3: Getting Started
It is important to consider the following points before logging into and configuring the
EPS:
◆You must configure the EPS IP address before any TCP/IP functionality is
available. (See Setting the IP Address on page 4-1) You cannot use the ThinWeb
Manager until you have configured an IP address.
◆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 pass-
word 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.
3.1 Configuration Methods
3.1.1 EZWebCon
The EZWebCon configuration software is the recommended way to configure the EPS.
EZWebCon’s graphical user interface guides first time users through the initial
configuration process and allows experienced users to update any configurable
parameters.
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 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 website and FTP
server. See Appendix D for more information.
3.1.2 Incoming Logins
You can log in via EZWebCon to configure the EPS. you can also use incoming LAT
and TCP/IP logins.

Services Getting Started
3-2
Incoming Telnet is only possible if your EPS has an IP address configured. 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 the CD-ROM.
Incoming logins do not prompt for a login password, so you may wish to disable them for
security reasons. If it is undesirable to disable incoming logins, the EPS can be configured
to prompt for a password with the Define Server Incoming Password Enabled command.
3.1.3 Console Terminal
To configure the EPS via a console terminal, attach a terminal to the serial port and press
the Return key. You will see a Local> prompt at which you can enter configuration
commands.
3.2 Services
With few exceptions, you must create a service before you can configure print queues 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 offers one login service and one default service per port. The service names are:
EPS_xxxxxx Login service
EPS_xxxxxx_S1 Serial port (Port_1) service
EPS_xxxxxx_P1 Parallel port (Port_2) service
EPS_xxxxxx_P2 Parallel port (Port_2) service, EPS2 only
The default service names are based on the server name; therefore the server name must be
no more than 13 characters. If you change the server name, the service names will change
as well. For example, changing the server name from EPS_xxxxxx to BIOLAB will change
the service names to BIOLAB_TEXTS1 and so on.
The default serial port services 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 EPS 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, see the Server Configuration chapter of the Print
Server Reference Manual located on the CD-ROM.

4-1
4: TCP/IP Configuration
The EZWebCon configuration software is the easiest way to configure the EPS. The fol-
lowing sections cover IP address configuration and print configuration methods for TCP/
IP hosts.
4.1 Setting the IP Address
The EPS IP address must be configured before any TCP/IP functionality is available. Use
one of the following methods to set the IP address: EZWebCon; a directed Ping packet;
a BOOTP, DHCP, or RARP reply; or commands entered via the command line interface.
4.1.1 Using EZWebCon
Use the following steps to assign an IP address using the EZWebCon Expert Shell.
1From the Action menu, select Assign IP Address.
2Enter or change the IP-related settings:
AFor Ethernet Address, enter the number that appears on the bottom label of
your EPS.
BFor IP Address, enter the desired IP address to use for this EPS.
CFor Subnet Mask, change the values provided only if you wish to use a mask
other than the default. The default value should be correct in most cases.
DFor Loadhost, enter the IP address of the loadhost where you intend to store
your operating code and SDK files (if used).
3Click OK.
4Reboot the EPS. EZWebCon will let you know whether the configuration was
successful.
Note: If you have an older version ofEZWebCon, refer to the Readme that
was included with it.
4.1.2 Using a Directed Ping Packet
The ARP/ping method is available underUNIX and Windows-based systems. If the EPS
has no IP address, it will set its address from the first directed IP packet it receives.

Setting the IP Address TCP/IP Configuration
4-2
On a UNIX host, create an entry in the host’s ARP table and substitute the intended IP ad-
dress and the hardware address of the EPS, then ping the EPS. This process typically re-
quires superuser privileges.
Figure 4-1: ARP and Ping on UNIX
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.
Figure 4-2: ARP and Ping on Windows
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 EPS 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 EPS, or allow an ad-
ministrator to Telnet into the EPS. Once logged in, the administrator can enter the Change
IPaddress command to make the address permanent.
Figure 4-3: Configuring Permanent IP Address
Any host wishing to access the EPS will have to be told the EPS’s IP address. This is typ-
ically configured in the unix file /etc/hosts or via a nameserver. Refer to the host’s docu-
mentation for additional information.

4.1.3 Using a BOOTP, DHCP, 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
1Connect to the serial port (Port_1) using a console terminal or a terminal emulation
program, and press Return. The serial port settings are 9600 baud, 8 bits, 1 stop bit,
no parity.
2Become the privileged user.
Figure 4-4: Becoming the Privileged User
3Enter the new IP address.
Figure 4-5: Configuring the IP Address
4.2 LPR Printing
The EPS provides two major methods of printing via TCP/IP: Berkeley remote LPR and
RTEL host software.
Two parameters must be configured for LPR printing:
1The IP address or host name of the EPS.
2The remote output queue (the name of the service on the EPS).
In addition, there are a few important things to note about LPR printing:
◆Windows for Workgroups, Windows 95, and Windows 98 do not support LPR di-
rectly; however, Lantronix has provided a peer-to-peer printing solution on the dis-
tribution CD-ROM.
◆Because of the way the LPR protocol is typically implemented on the host, the pro-
cessing 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.

LPR Printing TCP/IP Configuration
4-4
◆The EPS cannot print multiple copies of the print job when using the “-#n” lpr op-
tion.
◆If two print queues on the host refer to two services on the same EPS, they must use
separate spooling directories.
◆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.
4.2.1 LPR on Windows NT 3.5.1 (and later)
This section assumes that TCP/IP, Simple TCP/IP, and Microsoft TCP/IP printing have
been installed on the Windows NT host.
