How Upgrade an IPC Using Commands ?

Applicable Models

This fault may occur on IPC6100 series box network cameras.

Solution

NOTICE:

• Before      the upgrade, disable the firewall of the PC from which you want to upgrade      the IPC.
• Ensure      that the network connection between the IPC and the Secure File Transfer      Protocol (SFTP) server is normal. Do not disable the SSH tool, or power      off or restart the IPC during the upgrade.
• The      directory for storing the upgrade file cannot contain more than one .bin      file, otherwise, the upgrade will fail.
• The      upgrade file cannot exceed 35 MB, otherwise, the IPC may be faulty after      the upgrade file is uploaded.

1. Create      an SFTP server, and configure the user name, password, and file path.
2. Place      the upgrade file in the specified directory on the SFTP server or in a new      folder in the specified directory.
3. Use SSH to login to the IPC as the admin      user.
4. Run      the su - root      command to switch to the root      user.

NOTE:

For details about the default passwords of the admin and root users, see theIPC Online Help.

5. Run      the cd      /usr/app/bin/ command to go to the bin      directory.
6. Run      the ./update sftp      [IPAddr] [FilePath] [Mode] command to start the upgrade.

NOTE:

• [IPAddr]: IP address of the SFTP server.
• [FilePath]: path where the upgrade file is       stored on the SFTP server. Assume that the specified directory for       storing the upgrade file on the SFTP server is D:\update,       the path where the upgrade file is stored is D:\update\file,       and the upgrade file name is updatefile.       The value of this parameter is file/updatefile.       If the upgrade file is directly stored in the specified directory on the       SFTP server, you do not need to set this parameter.
• [Mode]: When this parameter is set to -f, the upgrade is performed forcibly. The       parameter can be left blank.

For example, if you run the ./update sftp 192.168.40.254 IPC6112_V100R001C10.bin command, the following information is displayed.

root@Huawei:/usr/app/bin# ./update sftp 192.168.40.254 IPC6112_V100R001C10.bin
