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 on the rear:
◆ Two 6-Gb/s by four-lane SAS 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 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 58 shows an example of the port connector (socket) and cable connector (plug)
with pull tab.
