There are two methods available to enable UEFI Secure Boot:
• From Lenovo XClarity Provisioning Manager
To enable UEFI Secure Boot from Lenovo XClarity Provisioning Manager:
1. Start the server and press the key specified in the on-screen instructions to display the Lenovo
XClarity Provisioning Manager interface. For more information, see the “Startup” section in the LXPM
documentation compatible with your server at
https://sysmgt.lenovofiles.com/help/topic/lxpm_frontend/
lxpm_product_page.html
.
2. If the power-on Administrator password is required, enter the password.
3. From the UEFI Setup page, click System Settings ➙ Security ➙ Secure Boot.
4. Enable Secure Boot and save the settings.
Note: If disabling UEFI secure boot is needed, select Disable in step 4.
• From Lenovo XClarity Essentials OneCLI
To enable UEFI Secure Boot from Lenovo XClarity Essentials OneCLI:
1. Download and install Lenovo XClarity Essentials OneCLI.
To download Lenovo XClarity Essentials OneCLI, go to the following site:
https://datacentersupport.lenovo.com/solutions/HT116433
2. Run the following command to enable Secure Boot:
OneCli.exe config set SecureBootConfiguration.SecureBootSetting Enabled --bmc <userid>:<password>@<ip_
address>
where:
– <userid>:<password> are the credentials used to access the BMC (Lenovo XClarity Controller
interface) of your server. The default user ID is USERID, and the default password is PASSW0RD
(zero, not an uppercase o)
– <ip_address> is the IP address of the BMC.
For more information about the Lenovo XClarity Essentials OneCLI set command, see:
http://sysmgt.lenovofiles.com/help/topic/toolsctr_cli_lenovo/onecli_r_set_command.html
Note: If disabling UEFI secure boot is needed, run the following command:
OneCli.exe config set SecureBootConfiguration.SecureBootSetting Disabled --bmc <userid>:<password>@<ip_
address>
System I/O board replacement (trained technicians only)
Use this section to remove and install the system I/O board from the system board assembly.
Note: When the server has a Liquid Assisted Cooling Module (LACM) installed, you must apply for a LACM
module handle (LACM heat sink bracket) first if you need to install or remove the system board assembly or
processor. However, while replacing the old LACM with a new one, you do not need to apply for a module
handle (LACM heat sink bracket) as the new LACM package contains it.
Remove the system I/O board
Follow the instructions to remove the system I/O board.
