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.
