Replacing the system board

Use this information to replace the system board.

Note

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.
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 and System-board internal connectors for more information). In addition, make sure the cables are inserted into the relevant cable clips.
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, Updating the Universal Unique Identifier (UUID), and Updating the DMI/SMBIOS data 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:

Read the safety information that begins on page Safety and Installation guidelines.
Grasp two holders and lower the system board into the chassis.
Figure 1. System board installation
Gently push the system board by holders to insert the external input/output connectors into their respective holes in the chassis.
Figure 2. System board installation
Install the screws to secure the system board to the chassis.
Figure 3. 9 screws
Install the USB embedded hypervisor flash device (see Replacing a USB embedded hypervisor flash device).
Install the system battery (see Replacing the system battery).
Install the DIMMs (see Replacing a memory module).
Install each microprocessor with its matching heat sink (see Replacing a microprocessor and heat sink).
Install the socket covers that you removed from the microprocessor sockets on the new system board and place them on the microprocessor sockets of the old system board, if you have not done so.
Reconnect to the system board the cables that you disconnected in step 12 of Removing the system board (see Internal cable routing and System-board internal connectors for more information).
Install the air baffle (see Replacing the air baffle), making sure that all cables are out of the way.
Install any removed adapters into the particular PCI riser-card assemblies (see Replacing an adapter on the PCI riser-card assembly and Replacing a ServeRAID adapter on the PCI riser-card assembly).
Install the PCI riser-card assemblies (see Replacing a PCI riser-card assembly).
Install the hot-swap rear hard disk drive cage (see Replacing the hot-swap rear hard disk drive cage).
Install the server top cover (see Replacing the server top cover).
Push the power supplies back into the server.
Reconnect the external cables; then, reconnect the power cords and turn on the peripheral devices and the server.
Start the Setup utility and reset the configuration.
- Set the system date and time.
- Set the power-on password.
- Reconfigure the server.
See Using the Setup utility.
Either update the server with the latest RAID firmware or restore the pre-existing firmware from a diskette or CD image (see Updating the firmware).
Update the UUID (see Updating the Universal Unique Identifier (UUID)).
Update the DMI/SMBIOS (see Updating the DMI/SMBIOS data).
