What Can I Do If the System Displays a Message Indicating that the Device Is Busy When I Attempt to Log In to the Web Page?

Applicable Models

This fault may occur on the following IPC models:

IPC2811-WD-Z20

IPC5811-WD-Z20

Symptom

Users fail to log in to the IPC. The messageThe device is busy. Try again. is displayed, and the device connection is unstable.

Possible Causes

This is a known issue in V200R001C01SPC100: The system time restores to the year of 1970 when the RTC battery runs out of power. When the system time is the year of 1970, the RTC interface fails to be set during device startup, which causes the failure to start the main program.

Solution

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.
   NOTE:

   How to obtain the upgrade package, see theObtaining Upgrade Packages.

3. Use SSH to log in 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 the User Guide corresponding to the faulty device.

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, the following information is displayed.

   root@Huawei:/usr/app/bin# ./update sftp 192.168.40.254 IPC6112_V100R001C10.bin 
    Update: Update Process Start! 
    Update: Update Sftp Start! 
    Update: Enter Function: UploadUpdateFile(sftp,192.168.40.254)

    admin@192.168.40.254's password:      
   

7. Enter the user name and password set in 1 as prompted.
   NOTE:

   Enter yes when the system asks you whether to continue.

   The following information is displayed:
