(Optional) Device Serial Number Configuration

When installing MEF Edge, you need to obtain the device serial number (SN) in either of the following ways.

By default, the Atlas 500 Pro AI edge server (model 3000) uses the SN automatically generated by the system. Skip this section.

Method 1: Manually configure the SN in the SN configuration file. If you write the specified SN into the SN configuration file before the installation, the software obtains the configured SN during the installation.
Method 2: The software automatically generates a random SN. If you do not write the specified SN into the SN configuration file before the installation, a random SN is generated during the software installation.

If you write the specified SN into the SN configuration file before the installation, the software obtains the configured SN during the installation.

Go to the path where the SN configuration file is stored directory where the software package is decompressed/config/edge_installer/.
Open the configuration file and write the value of the serialNumber field in the following position:
```
{
  "serialNumber": ""
}
```
- The value of serialNumber contains lowercase letters, uppercase letters, digits, underscores (_), and hyphens (-), and cannot start or end with an underscore (_) or hyphen (-). The maximum length is 64 bytes. Otherwise, MEF Center cannot deliver batch requirements through serialNumber.
- The value must be the same as the actual SN of the device. Otherwise, unknown problems may occur during MEF Center management through serialNumber.
- The value cannot be the same as the SN of a managed device. Otherwise, the management fails.
