Today, I'd like to share with you a knowledge point. The details are as follows:
Serial number (SN) is the exclusive identifier of an item. The SN can help after-sales personnel identify the maintenance period, or while a return is necessary, the SN can identify it's model, and return service can find the exactly the same part for you.
Serial number is a string of 12, 16, or 20 characters containing digits and letters, which can be found on a bar code label on device. All Huawei equipment and parts are coming with an bar code, which contents BOM code, factory information, version, and model information of about it.
A board bar code is a scanner-readable representation of data (such as the name, version, and model) relating to the board to which it is attached. For different batch of Huawei devices, it might come with one-dimensional bar codes and two-dimensional bar codes.
If you are looking for SN of a part, but don't know which one is the right label you're looking for, you can find the explaination in device documents.
I hope it will be helpful for you. Thank you!
