The rear panel features the host interface connectors to the printer. They include
the following connectors:
■

Ethernet AAUI
About the Ethernet AAUI connector
Activating the Ethernet AAUI connector is optional as indicated by “not
installed” printed above the connector. Installing the Ethernet card on the image
controller board activates the Ethernet connector. The Ethernet card contains the
hardware and code to support the EtherTalk, TCP-IP and Novell network
protocols. The Ethernet card also comes with an “installed” sticker to place over
the rear panel text “not installed.”
The TCP/IP protocol is activated by a printer-specific authorization code, sold as
a separate option. Simply installing the Ethernet card does not activate TCP/IP.
Refer to the Section 2 topic “About installing an Ethernet card” on page 1-8.
DIP switches
The rear panel features a bank of DIP switches to control certain aspects of the
printer's imaging. You can also use the DIP switches to control the self-tests of
the printer’s image processor board. Refer to the Chapter 6 topic “Image
processor self-diagnostics.”
