This manual describes the 3 Parallel Port Ethernet/Fast Ethernet
Multiprotocol Print Server, including a description of the print
server’s features, as well as the print server installation procedures
and troubleshooting self-test results.
For information about software configuration of the Print Server to
allow it to be used with your network, consult the PS Admin User’s
Guide included with your Print Server.

3 Parallel Port Multiprotocol Fast Ethernet Print Server User’s Guide
Introduction 1
1
1 INTRODUCTION
The Print Server is a compact print server which connects to your
Ethernet or Fast Ethernet network anywhere you wish to locate
printer services. It manages the flow of print files from your
workstations or file servers to its connected printers, delivering print
jobs to high-performance printers much faster than a file server or a
PC acting as a print server can.
Print Server Features
The Print Server improve network printing services in three ways:
♦The Print Server picks up the workload of managing print file
traffic to its connected printers. This provides workload relief
to your file servers, and allows the file servers' full capacity to
be used for file access or other direct services to network users.
On peer-to-peer networks, workstations can print directly to
the Print Server without increasing the load of another
workstation or server.

2Introduction
♦The Print Server's parallel printer ports are IEEE 1284
compliant high-speed bidirectional ports, which can transmit
to high-speed laser printers much faster than a PC's parallel
printer port. High-speed laser printers connected to the Print
Server's parallel ports can be operated at their full capacity.
♦Because the Print Server is very portable and inexpensive
compared to a PC-based print server, and because the Print
Server connects to your file servers through the network,
printers can be deployed to locations of maximum convenience
to users.
The Print Server offers extraordinary flexibility, operating with all
major network operating systems and protocols:
♦IPX/SPX
Novell NetWare 3.x, 4.x, 5.x (Using either bindery emulation or
native NDS)
♦TCP/IP
UNIX lpr/lpd (HP-UX, SunOS, Solaris, SCO, UnixWare, IBM AIX)
Windows NT, Windows 2000/98/95
♦NetBEUI
Windows NT, Windows 2000/98/95, Windows for Workgroups,
Microsoft LAN Manager, IBM LAN Server
♦AppleTalk
MacOS EtherTalk
Windows-based setup and administration software, PS Admin, is
supplied with the Print Server, making configuration and
management quick and easy. The Print Server also supports
configuration and management via the telnet protocol for networks
without Windows-compatible machines.

3 Parallel Port Multiprotocol Fast Ethernet Print Server User’s Guide
Introduction 3
External Features
This section describes the externally visible features of the Print
Server.
Port Connectors
The Print Server’s three printer ports are located on its rear panel.
Three identical parallel ports are labeled LPT1, LPT2 and LPT3.
These printer ports are independently configurable using the PS
Admin program or the print server’s telnet interface. (See the PS
Admin User’s Guide for information about configuring the print
server’s ports.)
Rear Panel Connectors
Network Cable Connector
The Print Server’s rear panel features an RJ-45 connector for
connection to 10Base-T Ethernet cabling or 100Base-TX Fast
Ethernet cabling (which should be Category 5 twisted-pair cable).
The port supports the NWay protocol, allowing the print server to
automatically detect or negotiate the transmission speed of the
network.

4Introduction
DC Power Connector
The DC power input connector is located on the Print Server’s rear
panel and is labeled DC 5V.
LED Indicators
The front panel of the Print Server features five LED indicators:
Front Panel LED Indicators
♦Power/Tx
◊Steady or flashing green confirms that the Print Server is
powered on.
◊The indicator blinks off briefly to indicate that the Print
Server is transmitting to the network.
♦Link/Rx
◊Steady or flashing green confirms that the Print Server has
a good connection to the Ethernet or Fast Ethernet network.
◊The indicator blinks off briefly to indicate that the Print
Server is receiving from the network.
♦LPT1, LPT2, LPT3
◊These LED indicators light to show that the Print Server is
transferring print data through the appropriate parallel
port.

3 Parallel Port Multiprotocol Fast Ethernet Print Server User’s Guide
Introduction 5
These three indicators are also used by the print server’s
power-on self test (POST) to indicate any hardware failures.

2 UNPACKING AND
INSTALLATION
This chapter explains how to install your Print Server and connect it
to the network. It also describes the print server self test indications.
Unpacking and Inspecting the Print
Server
Carefully remove all items from the package. In addition to this
Hardware User’s Guide, be certain that you have:
♦One 3 Parallel Port print server
♦One AC power adapter suitable for your country’s electric
power
♦One Print Server Installation CD
♦One Quick Installation Guide
If any item is missing, or if you find any damage or mismatch,
promptly contact your dealer for assistance.

Installing the Print Server
WARNING: Configuration problems may result if the Print
Server is powered up without first
establishing its network connection. Follow
this procedure to avoid complications at the
configuration stage.
1. Confirm proper operation of each of the printers to be connected
to the Print Server.
2. When you have confirmed proper operation of each printer,
switch its power off.
3. Confirm that your network is operating normally.
4. Connect the Print Server to the network, using the RJ-45
(10Base-T/100Base-TX) connector on the print server’s rear
panel.
5. While each printer is powered off, install a printer cable to
connect its parallel port to the printer port of the Print Server.
6. Switch on each connected printer.
7. Plug the AC power adapter’s DC output plug into the DC 5V
power socket on the rear panel of the Print Server.
8. Plug the power adapter into an electric service outlet. This
will supply power to the Print Server, as it has no external
power switch. The Power/Tx LED on the Print Server’s front
panel should light steady green, and the Print Server’s self-test
will proceed.

8Unpacking and Installation
Power On Self-Test
When the Print Server is powered on, it automatically performs a
self-test on each of its major components. The final result of the self-
test is signaled by the state of the LPT1, LPT2, and LPT3 LED
indicators following the self-test. Preliminary to the actual
component tests, the three LED indicators are tested to confirm their
steady and flashing operation.
Immediately after power-up, all five of the LED’s should show steady
green for several seconds. Then the LPT1, LPT2, and LPT3 LEDs
should flash on simultaneously three times. Irregularity of any of
the three LEDs during these LED tests may mean there is a problem
with the LEDs themselves. Contact your dealer for correction of any
LED problems before proceeding.
The actual component tests immediately follow the LED tests. A
normal (no fault) result is signaled by a series of three cycles of
sequential flashing of the three LEDs, followed by a quiescent state
with all three LEDs dark.
If the self-test routine traps any component error, then following the
LED tests the self-test will halt and the LED’s will continuously
signal the error according to the following table. In the event of any
such error signal, contact your dealer for correction of the faulty unit.

Testing Your Print Server
The PS Admin software includes a Print Test function for
confirmation of printer cable connections and functions. That
operational test can be completed after you have installed the PS
Admin software, and have configured your Print Server and its ports.
See the Testing Your Print Server section of the PS Admin User’s
Guide.
