| 2025-11-21|Back

OptiXOSN1500Bis a double-layer structure, the upper layer is the outlet board and power supply board slot area, with a total of 6 slots, and the lower layer is the processing board and auxiliary class single board slot area, with a total of 11 slots when the slots are not split; after splitting, there are 14 slots. The slots are distributed with corresponding relationships, including the corresponding relationship between the slots of the outlet board and the slots of the processing board, and the corresponding relationship of the pairwise slots. The device supports different types of single boards.
