Notes:
v If you have one PCIe3 x8 SAS RAID internal adapter (CCIN 57D7) in slot P1-C14 (base-storage
feature), one SAS cable connects the lower disk drive backplane connector (J1) to the P1 connector
on the adapter. A SAS cable connects the upper disk drive backplane connector (J2) to the P2
connector on the same adapter. See Figure 54.

Figure 54. Reconnecting the SAS cable in a base-storage configuration
v If you have two PCIe3 x8 SAS RAID internal adapters (CCIN 57D7) (split-disk feature), the short
SAS cable connects the upper disk drive backplane connector (J2) to the P2 connector on the
adapter in slot P1-C14. The long SAS cable connects the lower disk drive backplane connector (J1)
to the P1 connector on the adapter in slot P1-C15. See Figure 55.

38. Replace the SAS cable cover. Place the cover slots onto the pins on the side of the chassis. The
triangle symbol on the SAS cable cover lines up with the triangle symbol on the side of the chassis
when the cover slots and pins are aligned correctly. Push the cover forward toward the front of the
system until the handle latches in place. See Figure 56 on page 51.
