B – Multi-port Mini-SAS Cable Connectors – The backplane includes two pair of multi-port mini-
SAS cable connectors. Each pair contains primary SAS port and second SAS port providing
SGPIO and I/O signals for four SAS/SATA hard drives on the backplane. Cables can be routed
from matching connectors on the server board, installed add-in SAS/SATA RAID cards, or
optionally installed SAS expander cards for drive configurations of greater than eight hard
drives.
D – Power Harness Connector – The backplane includes a 2x2 connector supplying power to
the backplane. Power is routed to each installed backplane via a multi-connector 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.
