Notes:
1. Before you replace the system board, make sure that you backup any features on demand (FoD) keys
that were enabled. Remember to re-enable the features on demand (FoD) keys after installing the new
system board. For more information on Features on Demand (FoD), including instructions for automating
the activation and installation of the activation key by using ToolsCenter or Systems Director, see the
Features on Demand User's Guide at https://fod.lenovo.com/lkms under the Help section.
2. When you reassemble the components in the server, be sure to route all cables carefully so that they
are not exposed to excessive pressure and that they do not get pinched when you reinstall the system
board (see “Internal cable routing” on page 173 and “System-board internal connectors” on page 30 for
more information). In addition, make sure the cables are inserted into the relevant cable clips.
3. When you replace the system board, you must either update the server with the latest firmware or
restore the pre-existing firmware that the customer provides on a diskette or CD image. Make sure
that you have the latest firmware or a copy of the pre-existing firmware before you proceed. See
“Updating the firmware ” on page 95, “Updating the Universal Unique Identifier (UUID)” on page 114,
and “Updating the DMI/SMBIOS data” on page 116 for more information.
Important: Some cluster solutions require specific code levels or coordinated code updates. If the device is
part of a cluster solution, verify that the latest level of code is supported for the cluster solution before you
update the code
