2.9.2 SATA/SAS backplane connections
A SATA/SAS backplane comes pre-installed in the TS300-E5/PA4 and TS300-
E5/PX4 model. 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 “1.6 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.
Each SATA/SAS connector is labeled
(SAS PORT0, SAS PORT1, SAS
PORT2, SAS PORT3) so you can easily
determine their counterpart connectors
at the back side of the backplane. Refer
to the table for reference.
