 LAN Switch family of

Token-Ring LAN switches. The Model 600 joins the Model 800, providing a smaller
entry configuration (six slots). Both models allow flexible configuration with rich
functionality provided by the common set of Universal Feature Cards (UFCs) they
share. Similar to the Model 800, a typical network would benefit from the Model 600
by having each of its high-volume servers on dedicated full-duplex segments and
have client workstations on shared segments using standard Token-Ring concen-
trators, such as the IBM 8239 StackableToken-Ring Hub.
