Description of the problem

1.Why can't N2SL64 be used on OSN7500 and why can't N1SLH1 be used on GXCSA and EXCSA and UXCSA of OSN3500?

2、We know that the motherboard bus of OptiX OSN has two specifications: 622M and 2.5G. OSN 1500 and OSN 2500 only support 622M bus structure; SSN1GXCSA, SSN1EXCSA, SSN1UXCSA/B of OSN 3500 only support 622M bus structure; the rest of OSN 3500 and OSN 7500 The crossover boards can adapt themselves to 622M and 2.5G bus structures, so what is the bus rate of each single board?

Processing

1. The bus rate of N2SL64 single board is 622M, while all the slots of OSN7500 only have 8 buses at most, so it can't be used on OSN7500, while the bus rate of N1SL64 single board is 622M and 2.5G adaptive, which is inserted into OSN3500 with 622M rate, while inserted into OSN7500 with 2.5G rate.

2, N1SLH1 single board bus rate is 2.5G, while OSN3500 GXCSA and EXCSA, UXCSA cross board bus is 622M, even if the slot bandwidth is enough, it can not be used together.

3. How many buses are there in each slot of OSN3500 and OSN7500? In fact, OSN3500 can be calculated by dividing the access capacity of EXCSA in each slot by 622M, which can be calculated to support up to 16 buses, while OSN7500 can be calculated by dividing the access capacity of SXCSA in each slot by 2.5G, which can be calculated to support up to 8 buses.

4. The bus rates of various single boards are shown in the table.
