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 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.
Before you remove the system board from the server, take the following steps to save data, firmware,
and configuration data:
• Record all system configuration information, such as IMM IP addresses, vital product data, and the
machine type, model number, serial number, Universally Unique Identifier, and asset tag of the server.
• Using the Advanced Settings Utility (ASU), save the system configuration to external media.
• Save the system-event log to external media.
Note: 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.
To remove the system board, complete the following steps:
Step 1. Read the safety information that begins in “Safety” on page v and “Installation guidelines” on
page 36.
Step 2. Turn off the server (see “Turning off the server” on page 26) and all attached peripheral devices.
Disconnect all power cords; then, disconnect all external cables as necessary to replace the device.
Step 3. Pull the power supplies out of the rear of the server, just enough to disengage them from the server.
Step 4. Remove the server top cover (see “Removing the server top cover” on page 320).
Step 5. If you have the optional hot-swap rear hard disk drive cage installed, remove it from the server (see
“Removing an optional hot-swap rear hard disk drive cage” on page 182).
Step 6. Remove all PCI riser-card assemblies and adapters (see “Removing a PCI riser-card assembly” on
page 235, “Removing an adapter from the PCI riser-card assembly” on page 190 and “Removing a
ServeRAID adapter from the PCI riser-card assembly” on page 215).
Step 7. Remove the air baffle (see “Removing the air baffle” on page 322).
Step 8. Remove all heat sinks and microprocessors, and set them aside on a static-protective surface for
reinstallation (see “Removing a microprocessor and heat sink” on page 305).
Notes:
1. Be sure to keep the heat sink and microprocessor from each microprocessor socket of the old
system board together so that you can install them on the new system board together. For
example, when you remove the heat sink and microprocessor from microprocessor socket 1 of
the old system board , install them both on the same socket on the new system board.
2. Use an alcohol wipe to remove any thermal grease from the tabs on the microprocessor
bracket frame on the old system board.
Step 9. Remove all DIMMs, and place them on a static-protective surface for reinstallation (see “Removing
a memory module” on page 212).
Important: Make a note of the location of each DIMM as you remove it, so that you can later
reinstall it in the same connector.
