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 services print requests in the order they are received from the hosts. The serial port can also provide an outgoing modem service instead of a print service.

Each Ethernet Print Server has a unique name and network address, printed on the rear of the unit. This name is important for configuring print queues later; make a note of it before you install the unit.

There are 4 DIP switches on the rear of the Ethernet Print Server that are used for power-up options. As shipped, all switches are in the Off position. They function as follows (On = 1):

Sw1:	Off:	EPS will use the 10BASE-T network port.
	On:	EPS will use the AUI network port.
Sw2:	Off:	EPS will print status information to the serial port at boot
		time. It will send a PostScript compatible print job to the
		serial and parallel ports after loading code to test the physical
		ports. It will also send several broadcast network packets to
		check the network connection. You can also use the serial
		port as a login device (DYNAMIC access, see Section 6.3).
	On:	The serial port will be usable only via network connections
		(REMOTE access) and the EPS will not print any status
		information to the serial port at boot time, unless it cannot
		boot.
Sw3:	Currently unused.
Sw4:	Off:	Saved EPS settings are used.
	On:	EPS is restored to factory defaults at power-up time.

The EPS checks switches only at power-up time, so changing them while the unit is operating will not have any effect. After you connect the serial port to a print device and you configure the EPS, move Sw2 to the On position. Otherwise, the EPS may interpret any data from the printer

as a login attempt and you won’t be able to use the serial port.
