Hello everyone, today we're going to learn

2

00:00:02,300 --> 00:00:05,533

how to identify the board number of Huaqin Telecom

3

00:00:07,233 --> 00:00:10,266

The mainboards produced by Huaqin Telecom usually have a

4

00:00:10,266 --> 00:00:13,000

board number ending with "MB" printed on them

5

00:00:15,866 --> 00:00:17,366

When we read the board number

6

00:00:17,366 --> 00:00:20,200

we just read the 5 numbers and letters before MB,

7

00:00:20,966 --> 00:00:22,100

which is its board number,

8

00:00:22,300 --> 00:00:25,633

like NB2757

9

00:00:27,033 --> 00:00:28,800

For example, like this mainboard

10

00:00:30,133 --> 00:00:36,933

NB2500_PCB before MB is the board number of this mainboard

11

00:00:38,300 --> 00:00:41,833

When we are looking for the maintenance information about this mainboard,

12

00:00:41,833 --> 00:00:43,500

we can just search the board number

13

00:00:48,433 --> 00:00:52,766

The latter REV refers to the version number of this mainboard

14

00:00:53,766 --> 00:00:58,433

So, this is the board number identification method for Huaqin Telecom
