If you are instructed to return the defective system-board assembly, follow all packaging instructions, and
use any packaging materials for shipping that are supplied to you.

Important:

Make sure that both heat-sink fillers are installed on the defective system-board assembly that

you are returning, prior to shipment. Use the heat-sink fillers that were removed from the replacement
system-board assembly when you installed the processors. Do

not

install the processor socket dust covers

in the defective system-board assembly that you are returning.

Update the Universal Unique Identifier (UUID)

The Universal Unique Identifier (UUID) must be updated when the system board is replaced. Use the Lenovo
XClarity Essentials OneCLI to update the UUID in the UEFI-based server. Lenovo XClarity Essentials OneCLI
is an online tool that supports several operating systems; make sure that you download the version for your
operating system.

Notes:

You can use Lenovo XClarity Provisioning Manager to update the UUID for the server:

1. Start the server and press F1 to display the Lenovo XClarity Provisioning Manager system setup

interface.

2. From the System Summary page, click

Update VPD

3. Update the UUID.

To download Lenovo XClarity Essentials OneCLI, go to the following site:

https://datacentersupport.lenovo.com/us/en/solutions/HT116433

Lenovo XClarity Essentials OneCLI sets the UUID in the Lenovo XClarity Controller. Select one of the
following methods to access the Lenovo XClarity Controller and set the UUID:

• Online from the target system, such as LAN or keyboard console style (KCS) access

• Remote access to the target system (LAN based)

Step 1. Copy and unpack the OneCLI package, which also includes other required files, to the server. Make

sure that you unpack the OneCLI and the required files to the same directory.
