That is the correct cable for the expander backplane. If you have the 1:1 backplane then it is a different cable.
1:1 backplane:
JXNPP Cable H200/H700 to 3.5" 1:1 BP Port A1
W2HX5 Cable H200/H700 to 3.5" 1:1 BP Port A2
CNVF0 Cable H200/H700 to 3.5" 1:1 BP Port B1
3.5 expander backplane:
5X8NH Cable H200/H700 to 3.5” Exp BP(same cable for Port 0 and 1)
2.5 expander backplane:
Not compatible with the H200. Only compatible with H700 and LSI 9260-8i
Thanks
