Decoding the Barcode and Serial Number (SN) on OSN 8800 Boards

Huawei's OSN 8800 boards feature a barcode including serial number on the front panel that encodes key information, but what do the characters represent? In this blog, we'll break down the barcode and serial number (SN) naming conventions for the OSN 8800 board.

What Is a Board Barcode?

A board bar code is a scanner-readable representation of data (board name, version, and model) relating to the board to which it is attached.

There are one-dimensional bar codes and two-dimensional bar codes. Compared with a one-dimensional bar code, a two-dimensional bar code has a different form and adds the country of origin and item revision information.

One-dimensional Bar Code of a Board 

One-dimensional bar code of a board represents basic information about the board, including the BOM code, factory information, version, and model. For some boards, the bar codes also include the board characteristic codes. Each board characteristic code comprises information about frequency of signals, type of the optical module, wavelength, and so on.

Example: One-dimensional Bar Code of a Board

 

Two-dimensional Bar Code Label of a Board

Two-dimensional barcode label of a board represents board information, including the serial number, one-dimensional code, item number (BOM), item revision, board model, RoHS, country of origin, and two-dimensional code.

Serial Number Conventions 

Serial number (SN) is the exclusive identifier of the Huawei board. We can easily know the manufacturer date/month from board's SN characters. The value is a string of 12, 16, or 20 characters containing digits and letters.

Each 12-character serial number consists of a 2-character manufacturer code, a 3-character date code(year+month) and a 7-character sequence number.

    NOTE: The 3-character date code consists of the last two digits of the year (for example, "12" from 2012) and a character ranging from 1 to 9 and A to C which indicates the months from January to December respectively.

    Each 16-character serial number consists of the last 6 characters of an item number, a 2-character manufacturer code, a 2-character date code, and a 6-code sequence number.

      NOTE: In a 2-character date code, the first character is the last digit of the year ranging from 2000 to 2009 (for example, "4" represents 2004) or a character ranging from A to Z that indicates the year from 2010 to 2035 (for example, "B" represents 2011), and the second character is ranging from 1 to 9 and A to C which indicates the months from January to December respectively.

      Each 20-character serial number consists of the character string "21", an 8-character item number, a 2-character manufacturer code, a 2-character date code, and a 6-character sequence number.

        NOTE: The 2-character date code in a 20-character serial number is the same as that in a 16-character serial number.

        Example: Decoding the TN19LSC Serial Number

        After mastering the above BarCode rules, we can easily know OSN 8800 board's manufacturing information.

        Take the example of TN19LSC with a barcode of "1019C0014590" belonging to 12-character serial number:

        • 10: Manufacturer – Huawei
        • 19: Year – 2019
        • C: Month – December
        • 0014590: Sequence number

        By decoding the barcode, we can quickly gather crucial information about the OSN 8800 board without needing to access deeper technical documentation.  If you need more information about OSN 8800 board, please email us at sales@xponshop.com.
