6-Gb/s SAS port LED and port direction (input or output)
Figure 68 shows the LCC 6-Gb/s SAS port LED—a bi-color (blue/green) LED next to the
connector, either left or right—that indicates the link/activity of the SAS port. Figure 68
also shows a double circle (or dot) symbol
(for input) or a double diamond symbol
(for output).
Note: Looking from the rear of the DAE, LCC B is located on the top and LCC A is located on
the bottom (Figure 68).
