Replacing the system board
Use this information to replace the system board.
About this task
Note:
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 IBM
ToolsCenter or IBM Systems Director, see the IBM Features on Demand User's
Guide at /http://www.ibm.com/systems/x/fod/ 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 164 and “System-board internal connectors” on page 26 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 87, “Updating the Universal Unique
Identifier (UUID)” on page 108, and “Updating the DMI/SMBIOS data” on
page 110 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
To install the system board, complete the following steps:
Procedure
1. Read the safety information that begins on page “Safety” on page vii and
“Installation guidelines” on page 32.
2. Grasp two holders and lower the system board into the chassis.
