To change the default BMC password on the NVIDIA DGX Station A100, follow these steps:
1. Access the BMC Web Interface:
- Connect to the BMC by entering its IP address in a web browser. If you haven't set a static IP, ensure the BMC is connected to a network that provides DHCP.
- Log in using the default credentials, which are typically `admin` for both the username and password, unless you've already configured custom credentials during initial setup[4][10].
2. Change the BMC Password:
- Once logged in, navigate to the Settings section. This is usually found in the left navigation pane.
- Click on User Management.
- Find the user account you want to modify (e.g., the admin user) and click on it to edit its details.
- Enter a new password. The password must be at least 13 characters long for security reasons[1][2].
3. Alternative Method Using `ipmitool`:
- If you prefer using the command line or if the web interface is inaccessible, you can use `ipmitool`. This method requires direct access to the system.
- First, ensure `ipmitool` is installed on your system.
- To change the BMC password, use the following command. Replace `2` with the user ID of the account you want to modify (e.g., `2` for the admin user), and enter the new password when prompted:
bash
sudo ipmitool user set password 2
- This command will prompt you to enter the new password twice for confirmation[3][7].
4. Resetting to Default Passwords:
- If you need to reset the BMC to its default state (e.g., if you've forgotten the password), you can restore factory defaults without saving changes in the BMC web UI, or use the command:
bash
sudo ipmitool raw 0x32 0x66
- This will reset the admin and Administrator passwords to their defaults (`admin` and `superuser`, respectively), and delete all other users[1].
5. Security Considerations:
- Always ensure that the BMC is configured with strong, unique passwords and is isolated on a management network for security reasons[4][10].
