What is the board number?
Answer
It is a number for identifying each board when using multiple boards of the same model number in one rack.
Since it is the identification of boards of the same model number, if boards in the rack are all boards with different model numbers, they can be the same board number.
Example: When using three PEV boards in one rack
1st PEV board → board number 1
2nd PEV board → board number 2
3rd PEV board → board number 3
When there are two PEV boards and one AD board in one rack
1st PEV board → board number 1
2nd PEV board → board number 2
AD board → board number 1
