Note: This procedure should be performed only by trained service technicians.
Before you install the system-board assembly, complete the following steps:
1. Read “Safety” on page iii and “Installation guidelines” on page 637.
2. If the compute node is installed in an Flex System chassis, remove it (see “Removing a compute node
from a chassis” on page 639 for instructions).
3. Carefully lay the compute node on a flat, static-protective surface, orienting the compute node with
the bezel pointing toward you.
4. Obtain the following for use during the replacement procedure (see Chapter 5 “Parts listing, Types
2585 and 7906” on page 55).
• Alcohol wipes
• Bezel
• RFID tag (required only if the compute node came with a RFID tag attached to the bezel)
• Thermal grease
Important: When you replace the system board, you must update the compute node with the latest firmware
or restore the preexisting firmware. Make sure that you have the latest firmware or a copy of the preexisting
firmware before you proceed. See “Updating firmware and device drivers” on page 21 for more information.
To install the system-board assembly, complete the following

System-board
assembly
Step 1. Install all of the components in the following list that you removed from the old system-board
assembly onto the new system-board assembly:
• DIMMs and air baffles (see “Installing a DIMM” on page 654).
• I/O expansion adapters (see “Installing an I/O expansion adapter” on page 667).
• Fabric connector. (see “Installing a fabric connector” on page 660).
• ServeRAID controller. (see “Installing a ServeRAID controller” on page 665).
• Hard disk drives and hard disk drive fillers (see “Installing a hot-swap hard disk drive” on page
663).
• Microprocessors, heat sinks, and microprocessor heat-sink fillers. Use the microprocessor
installation tool that comes with the replacement microprocessor to remove each microprocessor
from the system-board assembly and install each one immediately in the new system-board
assembly (see “Removing a microprocessor and heat sink” on page 675 and “Installing a
microprocessor and heat sink” on page 678).
• Hard disk drive backplane (see “Installing the hard disk drive backplane” on page 662).
Step 2. If you are installing a new system-board assembly and did not install the old bezel on the new
system-board assembly, carefully remove the bezel from the old system-board assembly and install
it on the new system-board assembly (see “Removing the bezel” on page 648 and “Installing the
bezel” on page 649). If the old bezel will not attach securely to the new system-board assembly,
