The four-port 6-Gb/s SAS I/O module (labeled 6 Gb SAS on the latch handle) comes with
four SAS ports, one power/fault LED, and a combination link/activity LED for each port, as
shown in Figure 48. The SAS ports on this I/O module can interface at speeds of 6 Gb/s
for supporting serial SCSI protocol (SSP), serial management protocol (SMP), and SATA
tunneling protocol (STP) networks. The four-port 6-Gb/s SAS I/O module uses the
mini-SAS HD connectors (for more information describing the mini-SAS connector, see
Figure 67 on page 78).
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.
