Adding below the controller enclosure

1. Power down the array and existing disk enclosures.

Figure 12 (page 13) shows the cabling for an array with one P6500 EVA controller enclosure

and four disk enclosures. With the P6500 EVA, disk enclosure are balanced as evenly as possible

above and below the controller enclosures. Additionally, the controller enclosure and disk

enclosures are connected using Y-cables. The Y-cables enable each controller port to act as two

ports. For example, the DP-A port has both a DP-1 cable and a DP-2 cable.
