topology you will use and the cables and connector needed. The most
common topologies are shown on the following pages.
Figure 2-1 Single Attach Station - Single Attach Concentrator
• You can attach the adapter as SAS (Single Attach Station) to a
SAC (Single Attach Concentrator). Connect the B or A port on
the adapter to an M port on the concentrator.
Figure 2-2 Dual-Homed Station
• Or, you can attach the adapter as a dual-homed station to two
concentrators for additional fault tolerance. Connect the B port ofthe
adapter to an M port on the first concentrator. Connect the A port of
the adapter to an M port on the second concentrator.
