On the backside of each backplane are several connectors. The following illustration identifies each.
A – Power Harness Connector – The backplane includes a 2x2 connector supplying power to the backplane.
Power is routed to the backplane via a power cable harness from the server board.
B – Multi-port Mini-SAS Cable Connectors – The backplane includes two multi-port mini-SAS cable connectors,
each providing I/O signals for four SAS/SATA hard drives on the backplane. Cables can be routed from
matching connectors on the server board, add-in SAS/SATA RAID cards, or optionally installed SAS expander
cards.
C – SMBus Cable Connectors – The backplane includes a 1x5 cable connector used as a management
interface to the server board.
