Cascading Configuration, Backplane to Internal SAS Controllers

A server configures two internal RAID controller cards with zoning utility enabled (Flexible
Zoning). The 1st RAID controller card can be assigned to the first X number of drives. The
2nd RAID controller card can be assigned to the rest of the drives (45 - X).
Connecting Backplane in a Server to Internal RAID Controller Cards
1. Power down the system and remove the power cords from the rear of the power
supplies. Open the chassis cover and access the backplane as described in your
system manual.
2. Locate connectors CN1 and CN2 on the underside of the backplane in a server.
3. Plug the cables into connectors CN1 and CN2, then route them to connectors CN1 and
CN2 on the underside of the AOM-S3108M-H8L-P RAID controller card located within
the same server as the backplane, as illustrated in Figure C-7.
