As shown in Figure 69 on page
Each LCC also includes a bus (back-end port) identification indicator. The SP initializes
the bus ID when the operating system is loaded.
Note: An LCC might be in either the A slot, as shown, or the B slot above it, depending on
the DAE placement within a system. For example, the front DAE in some systems is in slot
A; the rear enclosure LCC is inverted, and in slot B.
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
◆
6-Gb/s mini-SAS x4 ports
The 3U DAE LCC supports two (one input and one output) 6-Gb/s mini-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

Note: The first half of the video shows an example of how to connect a mini-SAS HD cable
to a mini-SAS HD port while the second half shows how to connect a mini-SAS cable to a
DAE LCC port.
