DP-301 Print Server DP-301 Print Server Hardware Guide Service Features
DP-301 print servers improve network printing services in three ways:
â™¦ The DP-301 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 DP-301 without increasing the load of another workstation or server.
â™¦ The DP-301's IEEE 1284 compliant high-speed bidirectional parallel
printer port can transmit to high-speed laser printers much faster than a PC's parallel printer port. A high-speed laser printer can be driven at its full capacity.
â™¦ Because the DP-301 is very portable and inexpensive compared to a PC-
based print server, and because the DP-301 connects to your file servers through the network, the printer can be stationed at the location of maximum convenience to users.
The DP-301 offers extraordinary flexibility, operating with all major network operating systems and protocols:
Novell NetWare 3.x, 4.x (Using either bindery emulation or native NDS)
UNIX lpr/lpd (HP-UX, SunOS, Solaris, SCO, UnixWare, IBM AIX)
Windows NT, Windows 95, Windows for Workgroups, Microsoft LAN Manager, IBM LAN Server
MacOS EtherTalk 2 Introduction DP-301 Print Server Hardware Guide
Your D-Link DP-301 package includes PS Admin, a Windows-based setup and administration program, which makes configu-ration and management of your D-Link print servers quick and easy in a Windows environment. The DP-301 also has a Telnet interface for management communications. If Windows is not available on the station you choose for print server administration, then all configuration and management commands may be issued to the DP-301, and all console messages and management report information will be returned, via Telnet. External Features
This section describes the external features of the DP-301 print server. Rear Panel
The DP-301â€™s printer port, network port, and power input socket are all located on the rear panel
DP-301 Rear Panel Printer Port
The printer port, labeled LPT, is configurable by commands in the PS Admin program, or by commands issued to the DP-301 via Telnet. See the PS Admin Userâ€™s Guide for configuration procedures. Introduction 3 DP-301 Print Server Hardware Guide Network Port
The network port (RJ-45 receptacle) provides for connection to the network through 10Base-T Ethernet cabling, or Category 5 twisted-pair cable for 100Base-TX Fast Ethernet. This port has autonegotiation (NWay) functionality, which enables the DP-301 to automatically negotiate and set its data rate to the highest rate allowed by its network. DC Power Input
The DC power input socket has the label: The power supply included in your DP-301 package is correct for the DP-301. Substitution of other equipment may void warranty. LED Indicators
The front panel of the DP-301 comprises three LED indicators. See "Power-up and Self-Test," Chapter 2, for LED indications upon starting up the DP-301.
Pw / Tx
During operations following a normal startup, the LED indicators provide the following status signals:
Lin k / R x
Steady or flashing green confirms power on.
This indicator blinks (briefly dark) when the DP-301 is transmitting to the network.
Steady or flashing green confirms that the DP-301 has a good connection to the Ethernet or Fast Ethernet network.
This indicator blinks (briefly dark) when the DP-301 is receiving from the network.

â™¦ One DP-301 print server â™¦ One DC power adapter suitable for your electric power service â™¦ Two PS Admin for Windows software diskettes â™¦ One PS Admin Userâ€™s Guide â™¦ One lpr software diskette â™¦ One lpr user's guide â™¦ Velcro strips for optional mounting If any item is missing, or if you find any damage or mismatch, promptly contact your dealer for assistance. DP-301 Print Server Hardware Guide Installing the DP-301
Follow these steps for a trouble-free start of print-server operations with your DP-301. Please take particular notice of the warning in step 4: the network connection should be made before supplying power to the DP-301. 1. Confirm proper operation of the printer to be connected to the DP-301. 2. When you have confirmed proper operation of the printer, switch its
power off. 3. Confirm that your network is operating normally. 4. Connect the DP-301 to the network (through the RJ-45 receptacle on the
print serverâ€™s rear panel). WARNING:
Configuration problems may result if the DP-301 is powered up without first establishing its network connection. Follow this procedure to avoid complications at the configuration stage. 5. While the printer is power off, install a printer cable to connect its
parallel port to the printer port of the DP-301. 6. Switch printer power on. 7. Plug the DC power adapterâ€™s output plug into the DC power input socket
on the rear panel of the DP-301. 8. Plug the DC power adapter into an electric service outlet. This will
supply power to the DP-301. (The DP-301 has no power switch.) The DP-301â€™s self-test routines will proceed automatically.
Unpacking and Installation 7 DP-301 Print Server Hardware Guide Power-up and Self-Test
Whenever the DP-301 is powered up, two kinds of testing procedures follow automatically. The first procedure is just a programmed series of LED flashes, to confirm proper operation of the three LED indicators. The second procedure comprises programmed tests of each of the DP-301's major components. If any fault is found during the component test series, testing is halted and a continuous pattern of LED flashes signals the nature of the fault. LED Test Series
Immediately upon power-up, all three of the LED indicators will show steady green for several seconds. Then the LPT indicator will flash three times while Pw/Tx and Link/Rx remain steady. Irregularity of any of the LEDs during this LED test series indicates that there is a problem with the LEDs themselves. Contact your dealer for correction of any LED problems before proceeding. Component Test Series
The actual component tests immediately follow the LED tests. A normal (no fault) result is signaled by three flashes of the LPT indicator and the start of normal print server operation.
If any error condition is found during the component test series, then the test will halt with the LPT LED continuously signaling the particular error according to the following table. LPT Flash Pattern Error Type 8 Unpacking and Installation DP-301 Print Server Hardware Guide

In the event that any of the other listed error conditions is encountered on startup, contact your dealer for correction of the fault. Operational Test
The PS Admin software includes a Print Test function for confirmation of connections and functions. That operational test can be performed after you have completed installation of the PS Admin software, and the PS Admin procedures for configuring the DP-301. See instructions given in the PS Admin Userâ€™s Guide ("Getting Started Setting up Your Print Server" section, under the heading "Testing your Print Server"). Velcro-mounting the DP-301
The DP-301 can stand on the printer's tabletop, or may be Velcro-mounted to a side panel of the printer or another suitable surface next to the printer. To prepare for Velcro-mounting, separate the two parts of the supplied Unpacking and Installation 9 DP-301 Print Server Hardware Guide
Velcro tape (pull the "hook" tape apart from the "loop" tape -- the hook tape has stiff little plastic hooks, which give its surface a rough feel, and the loop tape has a mat of soft plastic filaments which gives it a smooth, soft feel).
The bottom housing of the DP-301 case features two corner markers which indicate the best location for applying the Velcro loop tape. Peel the white backing off of the loop tape, to expose its adhesive surface, and press it onto the bottom of the DP-301, between the corner markers.
Choose a mounting surface, and mounting attitude, which will afford convenient visual access to the DP-301's LED indicators, without cramping any of the wiring connected to the DP-301's rear panel. Peel the white backing off of the hook tape. Align the hook tape to match the alignment of the loop tape when the DP-301 is in the attitude you have chosen, and press the loop tape's adhesive back onto the mounting surface.
Mount the DP-301 by pressing its case firmly against the mounting surface to engage the hooks and loops of the Velcro tapes. 10 Unpacking and Installation A 3 PRODUCT SPECIFICATIONS Printer Connection Printer Port: IEEE 1284 standard bidirectional parallel interface with 25- pin connector.
