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 protocols to run “on top” of them. Some network nodes provide support for only one protocol set—for example, Macintosh® computers typically only speak AppleTalk®.

The EPS supports 4 major protocols:

•NOVELL® NetWare®

•TCP/IP

•Apple Computer’s AppleTalk (EtherTalk™)

•Digital Equipment Corporation’s LAT™

The EPS supports enough of each protocol to provide printer support for nodes of that type. For example, for AppleTalk, the EPS provides PAP (Printer Access Protocol) support, but not AFP (AppleTalk Filing Protocol). The EPS can use and interpret all 4 protocols at once, and can queue print requests from hosts using any of the 4 protocols simultaneously.

NOTE: The EPS does not allow outgoing connections to hosts from the EPS—it solely services requests from network hosts.

2.3 Additional Software You May Need

For NetWare, AppleTalk, and LAT, you can use the EPS as a print server with no additional host software and little or no configuration on the EPS. The EPS will allow printing on the serial and parallel port by default when it begins operating.

For TCP/IP systems, the EPS provides Berkeley remote-LPR support, which needs no EPS configuration or additional host software. If you cannot or choose not to use remote-LPR, you can use your host’s local LP or LPR printing via the RTEL host software. RTEL is discussed later.
