1. When you reassemble the components in the server, be sure to route all cables carefully so that they are
not exposed to excessive pressure.
2. When you replace the system board, you must either update the server with the latest firmware or
restore the pre-existing firmware from 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 85, "Updating the Universal Unique Identifier (UUID)" on page 102, and "Updating the
DMI/SMBIOS data" on page 104.

(IMM2) Advanced Upgrade and place it on the new system board. For information about the Advanced
Upgrade, see "Using the remote presence and blue-screen capture features" on page 97
4. Reactivate any Features on Demand features after replacing the system board. Instructions for
automating the activation of features and installing activation keys is in the Features on Demand User's
Guide. To download the document, go to http://www.ibm.com/systems/x/fod/, log in, and click Help.
5. 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.
Read the safety information in "Safety" on page v and "Installation guidelines" on page 31.
If you are replacing a server component in the server, you need to slide the server out from the rack
enclosure, turn off the server and peripheral devices, and disconnect the power cords and all external cables.
To replace the system board, complete the following steps.
Step 1. Touch the static-protective package that contains the system board to any unpainted metal surface
on the server; then, remove the system board from the package.
Note: When you are holding or replacing the system board in the server, avoid touching the cable
clips on the side of the chassis and the connectors on the system board. Be careful not to damage
any surrounding components inside the chassis.
Step 2. Align the system board with the chassis and replace the nine screws that you removed.
