A – 7-pin SATA I/O Connectors – The backplane has four 7-pin SATA/SAS I/O connectors, one
for each hard drive. A single multi-connector cable is routed from the backplane to a four port
mini-SAS connector on the server board or other optionally installed SATA/SAS host bus
adapter.
B – SMBus* Cable Connectors – The backplane includes a 1x5 cable connector used as a
management interface to the server board.
C – SGPIO Cable Connector – The SGPIO connector is a management interface used to
control the hard drive fault LEDs on the backplane. The SGPIO signals are routed through a
multi-connectors cable that is routed to a four port mini-SAS connector on the server board or
other optionally installed SATA/SAS host bus adapter.
D – Power Harness Connector - The backplane includes a 2x2 connector supplying power to
the backplane. Power is routed to the backplane through a power cable harness from the server
board.
