Refer to the following images when cabling multiple compatible drive chassis together with the RAID
chassis with dual-controller I/O modules connected using straight-through cabling.
Caution:
Using the straight-through cabling method, if a drive expansion chassis fails, the chassis that
follow the failed chassis in the chain are no longer accessible until the failed chassis is repaired or
replaced. Reverse cabling allows any drive expansion chassis to fail—or be removed—while
maintaining access to other expansion chassis.
Note:
For clarity, the images show only relevant details such as face-plate outlines and expansion
ports.
Note:
For 56 drive chassis, Controller A is located on the right, and Controller B is located of the left
side of the RAID chassis, as viewed from the back.
Example Dual-controller RAID Chassis with 1 Expansion Chassis
The following figure shows a dual-controller chassis cabled to an expansion chassis featuring dual-
expansion I/O modules. Controller I/O module 0A is connected to expansion module 1A (blue). Controller
I/O module 0B is connected to expansion module 1B (green).
