19. Complete the mode 2 connection of one enclosure (A) by using X cables (B) to two SAS adapter pairs
(C and D) as shown in Figure 28 on page 31, and then continue with “Connecting cables, power
cords, and installing covers” on page 33.
Notes:
• Each adapter in the SAS adapter pair 1 (C) has access to the other adapter and to drive bays D1 -
D12.
• Each adapter in the SAS adapter pair 2 (D) has access to the other adapter and to drive bays D13 -
D24.
• If 6 Gb SAS adapters are being used, they must be cabled by using 6 Gb SAS cables.
• For SAS adapter pairs, you can attach the cables to any adapter port when you use the same port in
both adapters.
