Overview
6-Gb/s SAS x4 ports — The 2U, DAE LCC supports two 6-Gb/s SAS x4 ports (labeled 6GB
SAS x4) on the rear of each LCC (A and B). This port is a 26-circuit SAS small form-factor
8088 (SFF-8088) specification connector (socket or receptacle) using an SFF-8088
specification mini-SAS 26-circuit cable (plug) with a pull tab.
Figure 27 shows an example of the port connector (socket) and cable connector (plug)
with pull tab.

out
(or one black
diamond, ) connection to prevent incorrect cabling.
