CHAPTER 2: Introduction
2. Introduction
The Ethernet Print Server High Speed (LE3810A-R2, LE3810AE-R2) provides
a high-speed parallel port for your parallel printer and a connection for your
twisted-pair Ethernet interface. It also provides support for Novell NetWare
and UNIX protocols.
The Ethernet Print Server (LE3820A, LE3820AE) provides a high-speed
parallel port for your parallel printer, and connections for an RJ-45 Uniport
and your Ethernet interface (thin or twisted-pair). It also provides support
for Novell NetWare, UNIX, and Apple protocols.
The Ethernet Print Server 4-Port (LE3840A, LE3840AE) provides three
high speed parallel ports and an RJ-45 Uniport to let you connect up to 4
printers, and a connection for your Ethernet interface (thin or twisted pair).
It supports the Novell protocol only.
The Ethernet Print Server 4-Port (LE3845A, LE3845AE) provides three
high speed parallel ports and an RJ-45 Uniport to let you connect up to 4
printers, and a connection for your Ethernet interface (thin or twisted pair).
It supports Novell NetWare, UNIX, and Apple protocols.
NOTE
The Uniport is serial by default. To use the Uniport as a parallel port, you
need a parallel port adapter (LT310A).
Both models of the Ethernet Print Server support Novell NetWare®versions
2.15 or 3.10 and higher and 4.00, AppleTalk®, and TCP/IP for Sun (Solaris®
1.1, 2.1), BSD System V Rel. 4, and DEC™ (ULTRIX™ 4.3) and HP®UNIX®
systems.
2.1 How to Configure Networks
• For Novell, use NetWare PCONSOLE to do the configuration.
• For AppleTalk, if you connect a PostScript®printer to parallel port #1, you
do not even need to configure. But if you have different requirements,
you can use the AppleTalk Administration program to configure the
Ethernet Print Server.
• For TCP/IP, use the Install script to set up your UNIX version to work
with Etherent Print Server printers.

ETHERNET PRINT SERVERS HIGH SPEED AND 4-PORT
2.2 Benefits
With each network protocol, the Ethernet Print Servers give you these
benefits:
• High performance—send data as fast as your printer can receive the data.
• Easy installation—install the Ethernet Print Server quickly in three easy
steps: configure and activate each network protocol, plug in the devices,
and plug in the power supply.
• Full print-server support—supports all print-server features defined for
Novell, AppleTalk, and TCP/IP.
• Put printers anywhere—Directly connect up to four printers, or three
printers and one input device.
• Versatility—The Ethernet Print Server incorporates Streams, a UNIX
technology, to provide a common interface for error handling, operating
system and hardware interfacing normally done differently by each NOS.
So printing can be performed simultaneously and concurrently using
different protocols on the same or different printers.
2.3 About the Ethernet Print Server Troubleshooting Software for
Workstations
The Ethernet Print Server provides the following troubleshooting tools for
each NOS:
• For Novell, NIMANAGE lets users troubleshoot problems by sending test
prints or viewing status reports or error logs on the Ethernet Print Server,
check or modify any configuration option not directly tied to the print
server, and change the print server name, the printer ports it uses, and
the password it uses to log in.
• For AppleTalk, the AppleTalk Administration Program provides functions
that let you reset the Ethernet Print Server, view the Ethernet Print Server
configuration or an error log, and change the printer setup.
• For TCP/IP, the software provides error messages and a status page to
alert you to data that was incorrectly input.
2.4 What’s in Your Package
The Print Server package contains the following:
• (1) Ethernet Print Server High Speed or Ethernet Print Server 4-Port
• Power adapter

• (3) Utility and diagnostics diskettes
2.5 Hardware/NetWare Requirements
The Ethernet Print Server hardware, software, and installation programs
require the following:
• NOS Version Supported: Novell NetWare version 2.15, 3.10, or 4.0
and above, any AppleTalk version (EtherTalk Phase II only), TCP/IP
compatible with Sun (Solaris 1.1, 2.1), BSD System V Rel. 4, DEC
(ULTRIX 4.3) and HP UNIX systems.
• Software requirements: NIMANAGE requires any IBM PC or compatible
with 512 KB of available random-access memory (RAM), one floppy drive
(for the Ethernet Print Server software), PC-DOS or MS-DOS®version
3.3x or later; AppleTalk Administration Program requires any Macintosh
computer with a disk drive; TCP/IP requires that the Ethernet Print
Server host software be installed on every host that spools directly to the
Print Server.
• Hardware connections: The Ethernet Print Server parallel ports connect
to any printer that has a Centronics parallel port, requiring a Centronics
male to Centronics female or DB25 male cable; the Ethernet Print Server
network connection supports 10-Mbps Ethernet networks that use either
ThinNet (10BASE2) or 10BASE-T hardware; the Ethernet Print Server
Uniport is compatible with the RS-232C standard supporting baud rates
of up to 19.2 kbps for input devices, and up to 115 kbps for output devices
using the UNIPORT-OUT adapter. (If you don’t use the adapter, output
devices will support baud rates of up to 19.2 kbps.)

3. Installation
3.1 Hardware Description
The Ethernet Print Server High Speed or 4-Port is a small unit that you can
attach to the side of your printer, or let it stand freely next to the printer.
The hardware allows users on an Ethernet network running Novell NetWare
versions 2.15 or 3.10 and above and 4.00 to access a parallel printer located
anywhere on the network.
3.2 Status Light Indicator
The status light indicator (the green LED) on the front of the Ethernet
Print Server unit lets you see the power-on status or diagnose problems.
See Chapter 7, Troubleshooting, for details.
3.3 Ethernet Print Server Back Panel
The back panel of the Ethernet Print Server High Speed has three connectors
and the Ethernet Print Server 4-Port has seven connectors. One connector is
for the power supply, and the remaining connectors are for the network or

3.4 Hardware Installation
Use the following steps to connect the network and devices, such as printers,
plotters, or minicomputers, to the Ethernet Print Server.
1. Connect the Ethernet Print Server to the network.
2. Connect the parallel printer(s).
3. Connect devices to the Uniport.
Do not connect the Ethernet Print Server’s power supply until ALL
hardware installation and software configuration steps are completed.
S TEP 1: C ONNECT THE N ETWORK TO THE E THERNET P RINT S ERVER
You can connect the network in one of two ways:
• Using the 10BASE-T Ethernet interface. The 10BASE-T network
connection uses a
4-wire twisted pair RJ cable to plug into the RJ-45 network connector
(marked 10BASE-T on the back panel) on the Ethernet Print Server.
Once you make the connection, you are finished with this step.
Go to Step 2.

CHAPTER 3: Installation
ThinNet Interface: Change Jumper First
You need to change a jumper inside the Ethernet Print Server unit before
you can print using the ThinNet Ethernet interface.
How to Change the Ethernet Print Server Jumper
The Ethernet Print Server is designed to withstand minor bumps and bangs
without accidentally opening. Follow the steps in this section to open the
plastic unit if you need to change the jumpers from the Ethernet 10BASE-T
interface to the ThinNet interface. The default is the 10BASE-T interface.
1. Make sure you do not have the Ethernet Print Server unit plugged into a
wall outlet. If it is, unplug the power cord before you open the unit.
2. Hold the side of the unit against your body. Grab the side that is the
farthest away from your body and press the bottom half of the unit inward
toward you. Pull the two halves apart, as shown in Fig. 3-2.
Fig. 3-3. Opening the Unit.
Press the top
cover inward
toward you,
and, pull the
two halves
apart.
Push the
bottom
cover in
and lift up.

16
ETHERNET PRINT SERVERS HIGH SPEED AND 4-PORT
3. Locate the jumper on the component side of the board.
Fig. 3-4. Jumper Location.
4. To change the default jumper from 10BASE-T to ThinNet, move the
jumper from its present setting TP (on one side of the jumper) to the
jumper setting marked THIN.
Jumper is located
here to the front of
the unit. The
default setting
shown here is for
10BASE-T.
Rear panel is
shown here.

17
CHAPTER 3: Installation

This is the default setting for the
Ethernet Print Server. Move the
jumper from the pins labled TP
to the pins labled THIN. Always
cover the middle row of pins for
either setting.
Once you change the jumper, it
should look like the illustration
above. You can then use your
Thinnet interface for your
network connection.

18
ETHERNET PRINT SERVERS HIGH SPEED AND 4-PORT
• Using a ThinNet Ethernet interface. The ThinNet Ethernet wires use
a BNC T-connector (not included) to plug into the BNC port on the
Ethernet Print Server (marked ThinNet on the back panel). Thin
Ethernet cable is a quarter-inch coaxial cable (usually RG-58/U) that
uses the cylindrical BNC T-connector to attach to the BNC port.
Fig. 3-6. ThinNet Interface.
Connect a BNC T-connector
directly to the Ethernet Print
Server BNC port as shown in
the picture to the left. Any
other type of connection will
not work with the Ethernet
Print Server.

CHAPTER 3: Installation
Wrong BNC Connections to the Ethernet Print Server
Fig. 3-6 shows two incorrect ways to make the BNC connection. You
must always make your BNC connection using a T-connector (which is
not provided with your Ethernet Print Server) directly connected to the
port marked ThinNet.
Fig. 3-7. Wrong Connections.
This connection is wrong because
the T-connector is not directly
connected to the Ethernet Print
Server. The cable between the
T-connector and the Ethernet
Print Server BNC connector forms
another branch on the network
—which is not allowed with the
Ethernet Print Server.
Ethernet Print Server
Ethernet Print Server
This connection is wrong because
a T-connector is not used.
