Changing the Initial Password for the iBMC U-Boot

Changing the Initial Password for the iBMC U-Boot

Scenarios

Log in to the Server Node over a serial port and change the initial password for the iBMC U-Boot to improve operation and maintenance (O&M) security.

NOTE:
  • The system enables the password complexity check function by default.
  • A simple password is easy to crack and makes the system vulnerable. You are advised to use a password that meets complexity requirements or to enable the password complexity check function.
  • To ensure system security, change the initial password at the first login and change the password periodically.

The iBMC U-Boot is a piece of underlying software that is used to configure basic settings, for example, initializing hardware devices and setting up memory space mapping, to prepare for commissioning the OS.
