Table 4-17 x3690 X5 hard drive backplanes
As listed in Table 4-17, the backplane option part numbers include the necessary cables to
connect the backplane to the SAS controller. The
short SAS cable is needed when installing a
hard drive backplane for 2.5-inch bays 1 - 8 (the left half of the drive bays in the server, when
looking from the front). The
long SAS cable is used for hard drive backplanes for 2.5-inch
bays 9 - 16 (the right half of the drive bays, when looking from the front).
When configuring an order by using feature codes, for example, with configure-to-order
(CTO), the feature codes for the backplanes do not include the cables. You must order the
cables separately, as listed in Table 4-18.

Using the ServeRAID Expansion Adapter: When using this adapter, the adapter must be
installed in PCIe slot 1. Short SAS cables are used to connect the two ports of the
ServeRAID controller to the two controller I/O ports on the expander. All four backplane
SAS cable connections are connected to the ServeRAID Expander using the long SAS
cables that are shown in Table 4-18 on page 146.
