Replacing the system board
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 https://www-304.ibm.com/systems/x/fod/index.wss 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 so that they do
not get pinched when you reinstall the system board. 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 71, "Updating the Universal Unique
Identifier (UUID)" on page 92, and "Updating the DMI/SMBIOS data" on page
95 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:
1. Read the safety information that begins on page Safety and "Installation
guidelines" on page 30.
2. Slide the system board into the chassis with a small angle toward to the hard
disk bays. Make sure the system board is seated into the chassis flat and the
no standoff is blocking the system board.
