and two expansion trays. The cable connections on the B-side are reversed (the cable
from the controller A expansion port goes to the In port of expansion tray 1; the

Two more SAS cables are required for each additional tray.

2. Locate In and Out expansion ports at the A-side and B-side back of the
expansion tray (
FIGURE 2-17).
3. Connect one SAS cable between the Controller A expansion port and the A-
side expansion In port of expansion tray 1 (
FIGURE 2-19).
4. Connect one SAS cable between the Controller B expansion Out port and the
B-side expansion In port of expansion tray 2 (
FIGURE 2-19).
