Figure 32. Hard Disk Drive Interface Rear Connectors
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.

Cypress* CY8C22545 Enclosure Management Controller
The backplanes support enclosure management using a Cypress* CY8C22545 Programmable
System-on-Chip (PSoC*) device. The CY8C22545 drives the hard drive activity/fault LED, hard
drive present signal, and controls hard drive power-up during system power-on.
