Connecting the SAS cables
The following table provides information for connecting the SAS cables to the
drive backplanes (BP) based on the backplane slot and supported drive backplane
configurations:

backplane
v
Connect two
SAS cables
from BP 1 to
the two SAS
signal
connectors on
the system
board.
v
Connect two
SAS cables
from BP 2 to
the connectors
on the PCIe
adapter.
v
Connect two
SAS cables
from BP 3 to
the connectors
on the PCIe
adapter.
v
Connect two
SAS cables
from BP 4 to
the connectors
on the PCIe
adapter.
Note: Follow this general rule for connecting the SAS signal cables to the drive backplanes
and adapters:
v
Port 0 on the drive backplane to Port 0 on the adapter
v
Port 1 on the drive backplane to Port 1 on the adapter
