TrungDV The issue is due to the backplane having improper jumper setting on the expander from the factory.  To correct this remove J15 from the C2100 3.5" backplane, or  J7 from the C2100 2.5"  backplane.  Refer to the below images for help in locating the jumpers.  3.5" [IMAGE] 2.5" [IMAGE] Let me know if this helps resolve the issue.
