Two-port 10-Gb/s optical I/O module LEDs
The two-port 10-Gb/s optical I/O module has three types of status LEDs. Figure 42 shows
the LEDs and Table 26 describes them.

Four-port 6-Gb/s SAS I/O module
The four-port 6-Gb/s SAS I/O module comes with four SAS ports, one power/fault LED, and
a combination link/activity LED for each port (Figure 43 on page 52). 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 connectors (for more information
describing the mini-SAS connector, see Figure 58 on page 70).
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.
The four-port 6-Gb/s SAS I/O module increases the back end capability of the VNX5700
platform. Basically, it adds an additional four back end buses to each SP in the SPE.
