Cascading Configuration, Backplanes to External Controller
Connecting Backplanes in JBODs to External Controller
1. Power down the system and remove the power cords from the rear of the power
supplies. Open the chassis cover and access the backplanes as described in your
system manual.
2. To connect the 1st backplane connectors CN1 and CN2 to the controller located in
a server, plug the External MiniSAS HD to External MiniSAS HD 1m cables (CBL-
SAST-0573) into the JBOD in upstream port of the JBOD where the 1st backplane is
located and into connectors CN1 and CN2 on the underside of the AOM-S3108M-H8L-P
SAS controller or AOM-S3008-L8-SB HBA, as illustrated in Figure C-5.
