U-Boot Commands

Logging In to U-Boot

Scenarios

Log in to U-Boot of the iBMC over a serial port.

U-Boot commands are used to load underlying software and debug underlying devices. Only qualified maintenance engineers can use U-Boot commands.
Prerequisites
  • User name and password for logging in to the iBMC

    The default user name is root, and the default password is on the product nameplate.

  • Password for logging in to U-Boot

    The default password is Huawei12#$.

For security purposes, change the initial password after the first login and change your password periodically.
Procedure
  1. Log in to the iBMC CLI over the serial port.
  2. Restart the iBMC.

    iBMC:/->ipmcset –d reset
    This operation will reboot iBMC system. Continue? [Y/N]:

  3. Type Y and press Enter.
