SATA/SAS backplane cabling
The system comes with a pre-installed SATA/SAS backplane. The SATA/SAS backplane
has four 22-pin SATA/SAS connectors to support Serial ATA hard disk drives and SAS hard
disk drives. The backplane design incorporates a hot-swap feature to allow easy connection
or removal of SATA/SAS hard disks. The LEDs on the backplane connect to the front panel
LEDs to indicate HDD status. See section 1.7 LED information for details.
Front side
The front side of the SATA/SAS backplane faces the front panel when installed. This side
includes four SATA/SAS connectors for the hot-swap drive trays.
