HighPoint RocketRAID 2320 - Manual (Page 15)

Each cross-adapter cable has a 3-pin and 4-pin connector, designed for insertion into
JP3 and JP4 respectively.
Example installation:
For a 16-hard disk, 2-card cross-adapter RAID configuration, install a second card
into the next available PCI-Express slot. Insert one end of the cross-adapter cable into
the appropriate jumper on the first adapter (3-pin connector to JP3, 4-pin connector to
JP4), and the remaining connector into the appropriate jumper on the second adapter.
There is no particular connector-to-jumper requirement. Any given connector can be
inserted into the corresponding jumper on either card.
