In Huawei optical transmission boards, SSN4 is equal to SSND00, and generally speaking, the same boards that display different product name have the same feature code, like SSN4SL6402 and SSND00SL6402. But When it comes to Huawei service board SSN4EGS411 and SSND00EGS412, some customers are misguided and some customers are asking that whether we delivered the wrong model of board to them, because In huawei BOQ, it is show as SSND00EGS412, here version code is ND00, feature code is 412; But in board front panel, it show as SSN4EGS411, here verison code is N4, but feature code is 411. Actually they are the same board.
To avoid this confuse, we suggest when ordering a EGS4 board, it better to comment with a optical specification behind like: (1000BASE-LX).
For example, when you are about to order a SSN4EGS411 board, you must select maybe you will choose configuration(slots and transmission range etc.) like as follow:
After you selected the configuration of this board, it will appear message box like this:
The product name shows as SSND00EGS412. But the product name that shows on the board is SSN4EGS411.
So when you buy this model of board later, you won’t be confused again.
