The 3U, 15 (3.5-inch) DAE LCC input/output ports and connectors
The 3U, 15 (3.5-inch) DAE LCC supports the following I/O ports and connector on the rear:
◆ Two 6-Gb/s SAS x4 ports
◆ One management (RJ-45) connector to the SPS (not used)
6-Gb/s SAS x4 ports
The 3U, DAE LCC supports two (one input and one output) 6-Gb/s SAS x4 ports (labeled 
6GB SAS 0 x4 and 1 x4) on the rear of each LCC (A and B). This port provides an interface 
for SAS and NL-SAS drives on the DAE. This port is a 26-circuit SAS small form-factor 8088 
(SFF-8088) specification (socket or receptacle) using an SFF-8088 specification mini-SAS 
26-circuit cable (plug) with a pull tab.
Note: Each SAS cable is keyed with an 
in
 and 
out
 connection to prevent incorrect cabling.
Figure 67 shows an example of the port connector (socket) and cable connector (plug) 
with pull tab.
