IBM x3650 M3 Installation And User Manual page 99

a. If you are connecting the shorter SAS signal cable to a ServeRAID-BR10i
v2 SAS/SATA Controller, the connectors are reversed. You must connect
the shorter SAS signal cable to the connector that is labeled "Port 4–7",
which is the connector that is not the closest to the edge of the controller.
b. If you are connecting the longer SAS signal cable to a ServeRAID-BR10i v2
SAS/SATA Controller, the connectors are reversed. You must connect the
straight connector end of the longer SAS signal cable to the connector that
is labeled "Port 0–3".
24. Remove the PCI riser-card assembly (see "Removing a PCI riser-card
assembly" on page 46).
25. Orient the SAS controller so that the connectors are on the underside of the
controller. Install the SAS controller in the connector on the PCI riser card.
(See the previous illustration and see "Installing a PCI adapter" on page 53.)
26. Install the PCI riser-card assembly in the server (see "Removing a PCI
riser-card assembly" on page 46).
27. Connect the free end of the remote battery cable to the battery on the remote
battery tray. For more information, see "Installing a ServeRAID SAS controller
battery on the remote battery tray" on page 139.
28. Connect the SAS signal cables to the SAS expander card:
a. Connect the SAS signal cables from hard disk drive backplane 2 to the
right front connectors on the SAS expander card (as facing the front of the
server).
Figure 81. Connecting SAS signal cables
b. Connect the SAS signal cables from hard disk drive backplane 1 to the left
front connectors on the SAS expander card (as facing the front of the
server).
29. Connect the loose end of the SAS signal cables (the cables have straight
connectors and are already connected to the ServRAID controllers) to the rear
connectors on the SAS expander card. Route the cable underneath the cable
retention features on the baffle. See the illustration.
Note: The cables that connect to a ServeRAID-BR10i v2 SAS/SATA Controller
are reversed.
