Support for AppleTalk on Earth Sciences network ends April 7, 2008



Last revision March 14, 2008

This page primarily applies to people using Apple Macintosh computers, or managing networked printers. Windows PCs and Linux systems are not affected, unless you specifically installed third-party AppleTalk software, or have configured your system to print via pangea.

AppleTalk is a networking protocol invented by Apple Computer in the 1980s to provide simple printer and file sharing on local area networks. Because it was never really adopted by other computer manufacturers, and does not scale well to large networks, Apple began providing alternative networking support in the 1990s using the Internet standard TCP/IP protocols. Although all Macs and most printers still ship with AppleTalk support, it is no longer enabled by default and not recommended for general use.

We have always supported AppleTalk on the Earth Sciences network, primarily to access printers, but also to access an AppleShare file server installed on pangea, which is also being discontinued. In order to support a large number of devices on AppleTalk in an organized way, we have used an AppleTalk router to create "zones", mostly named geographically, for example, ES-Mitchell-B or ES-Green-West.

On April 7, support for AppleTalk on the Earth Sciences network will end. Our AppleTalk router will be permanently disabled. This will collapse all zones into a single, unnamed one, which will disrupt any existing uses. At the same time, the AppleShare server and most printer queues on pangea will be disabled, as they are configured to use AppleTalk. Neither our CRC desktop consultants nor the School's network support staff will provide any help with further use of AppleTalk, except to transition you to the more modern TCP/IP protocols.

Here is what you should do to prepare for the end of AppleTalk support. Or put in a request to have our CRC consultants help you via the web form at
