2.1.3 Single-attached Station
A single-attached station (SAS) is an FDDI station that uses only one
connection (an S port) for connection to the FDDI ring.
Figure 2-3 shows the ATX, with a 3F00-01 installed, configured as an
SAS, connected to a master port of a dual-attached concentrator (DAC)
on the main FDDI ring.
