ETHERNET PRINT SERVER 2. Introduction 2.1 Description The Ethernet Print Server (EPS) is a multiprotocol print server. It provides network access to printers for a variety of network protocols and operating systems. It has an AUI port for connection to an external Ethernet transceiver, and an RJ-45 connector for use with 10BASE-T. It provides one serial port and one parallel port to which network nodes can spool print jobs. The Ethernet Print Server queues multiple pending jobs, and servi

CHAPTER 2: Introduction If you cannot move a switch by hand, use a small screwdriver or pen to gently flip the switch. Make sure each switch is fully in the On or Off position; inconsistent operation may result if the switch is between settings. 2.2 Protocols Supported A network protocol is a method of communicating over the Ethernet—each protocol specifies a certain arrangement of data in the Ethernet packets, and provides different services for its users. Many protocols also allow other pr

ETHERNET PRINT SERVER 2.4 EPS Configuration Depending on your network, the EPS might work properly right out of the box with no additional configuration. If your network installation will use the AUI port instead of 10BASE-T, you will need to change one of the DIP switches before you install the unit. Remember, you need no configuration if you’re using NetWare, AppleTalk, and LAT. For TCP/IP, the unit needs an IP address and may use a specific IP gateway host. There are several ways to conf

CHAPTER 2: Introduction In all three cases, the EPS is transparent to the user and uses normal print syntax from the host—simply specify the file and queue name in the print command. 11

ETHERNET PRINT SERVER 3. Installation This chapter covers only the installation of the EPS in the network and attaching the print devices. For details on installing the optional RTEL software or installing a new download image (to re-load the EPS’s code in the Flash-ROMs) see Appendix E. This section assumes a basic understanding of network installations, and host setup in NetWare, TCP/IP, AppleTalk, or LAT environments. We strongly recommend reading this entire section completely before star

CHAPTER 3: Installation 4. If Sw2 is off, the EPS will print status information to the serial port as it boots. Attach a console device (we recommend using a terminal) to the serial port of the server. The default serial port settings are 9600 baud, 8 bit characters, and no parity. You can also attach the parallel port to a print device at this time. NOTE: You can change the console device to a printer once you boot the EPS, but we recommend using a terminal the first time in case the EPS nee

ETHERNET PRINT SERVER After the EPS loads the Flash code and the unit is running normally, the OK LED will blink once each 2 seconds. Depending on SW2’s position, the EPS will print a greeting to the serial port when the unit is operational: Ethernet Address: xx-xx-xx-xx-xx-xx IP Address: undefined Lantronix EPS1 Print Server Diagnostics Report: Interface: 10BASE-T Memory: 256KB Gate Array: Vers 3 Errors Reported: None Attempting BOOTP: no reply received. Attempting RARP: no reply received.

CHAPTER 3: Installation 3.1 How Do I Know It’s Working? If the EPS appears to be working (OK LED is blinking slowly) and the unit is connected to the network, there are various ways to confirm that the unit is visible to network hosts: • If the EPS has an IP address, you can PING it from a TCP/IP host— the EPS should respond correctly. • From a NetWare host, the EPSCON utility (provided on the enclosed NetWare utilities disk) will show available print servers (including the EPS) if you enter EP

ETHERNET PRINT SERVER If a terminal is not attached to the serial port, you can still detect a boot error (typically network-related) via the LEDs. If the OK and network LEDs are blinking rapidly (2-3 times per second) in unison, a boot failure occurred. Once the EPS boots and is running normally, the OK LED will blink once every 2 seconds. 3. If all the tests pass successfully, but the code in the Flash-ROMs is corrupt, the EPS will attempt to download new code from a network host. Both the

CHAPTER 4: Host Configuration 4. Host Configuration Host configuration is broken down by protocol, since none of the procedures are common to any of the protocols. You must enable the protocol on the EPS service before clients will be able to see and use that service. You should be familiar with the protocol and host setup; refer to the documentation that came with your operating system software for more details. You must remember 3 resource names as you configure the EPS and host(s). Each EP

ETHERNET PRINT SERVER You must perform these steps on each file sever that will need access to the EPS queues. Users on each file server wishing to print will specify the file server’s queue name; the file server and EPS will decide which, if any, of the EPS’s queues can service the requests. Note the name of the EPS from the back label. The following steps refer to NetWare v3.11, but are similar for v2.x: 1.
