0 ABOUT THIS G UIDE This manual describes the DP-300 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 DP-300 to allow it to be used with your network, consult the Print Server Administration User’s Guide included with your DP-300.
DP-300 Multiprotocol Fast Ethernet Print Server User’s Guide 1 1 I NTRODUCTION The DP-300 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.
♦ The DP-300 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-300 without increasing the load of another workstation or server.
DP-300 Multiprotocol Fast Ethernet Print Server User’s Guide Windows-based setup and administration software, PS Admin, is supplied with the DP-300, making configuration and management quick and easy. The DP-300 also supports configuration and management via the telnet protocol for networks without Windows-compatible machines. External Features This section describes the externally visible features of the DP-300 print server. Port Connectors The DP-300’s three printer ports are located on its rear panel.
Network Cable Connector The DP-300’s right side 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. DC Power Connector The DC power input connector is located on the DP-300’s right side panel and is labeled DC 12V.
DP-300 Multiprotocol Fast Ethernet Print Server User’s Guide ◊ Steady or flashing green confirms that the DP-300 is powered on. ◊ The indicator blinks off briefly to indicate that the DP-300 is transmitting to the network. ♦ Link/Rx ◊ Steady or flashing green confirms that the DP-300 has a good connection to the Ethernet or Fast Ethernet network. ◊ The indicator blinks off briefly to indicate that the DP-300 is receiving from the network.
2 2 UNPACKING AND I NSTALLATION This chapter explains how to install your DP-300 print server and connect it to the network. It also describes the print server self test indications, and tells how to wall-mount your print server. Unpacking and Inspecting the Print Server Carefully remove all items from the package.
DP-300 Multiprotocol Fast Ethernet Print Server User’s Guide Installing the DP-300 WARNING: Configuration problems may result if the DP300 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 DP-300.
Power On Self-Test When the DP-300 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 COM LED indicators following the selftest. 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.

443 PP 7 8249 LQ :3 PP 5 627 LQ When setting the screws into the wall or partition, leave about 3 mm (1/8 in) between the head of each screw and the wall surface. Then place the DP300 so that the mounting sockets on the bottom of its case fit over the two screws. Press the case gently toward the wall and slide the case at a 45° angle downward and leftward to engage the screwheads in the slots of the mounting sockets.

B 4 P ORT P INOUTS This appendix shows the pinouts of the DP-300 parallel and serial printer ports. Parallel Ports The following table lists the pinouts of the print server’s 25-pin parallel port connector (identical to the connector used on most personal computers), as well as the 36-pin Centronics connector used on most printers. Signal names beginning with n are active-low signals.
