Lenovo Flex System x480 X6 Compute Node Installation And Service Manual page 1047

1. This procedure should be performed only by trained service technicians.
2. The base assembly includes the chassis and system board.
Before you install the system-board components, complete the following steps:
1. Read "Safety" on page v and "Installation guidelines" on page 973.
2. If the compute node is installed in a Lenovo Flex System chassis, remove it (see "Removing a compute
node from a chassis" on page 975 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 items for use during the replacement procedure (see Chapter 5 "Parts listing,
Types 7196 and 4258" on page 57):
• Alcohol wipes
• Bezel
• Thermal grease
Important: When you replace the base assembly, 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 27 for
more information.
To install the components on the system-board assembly, complete the following steps.
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.
• Center partition (see "Installing the center partition" on page 982).
• DIMMs and air baffles (see "Installing a DIMM " on page 991).
• eXFlash DIMMs, (see "Installing an eXFlash DIMM" on page 1000).
• Fabric connectors (see "Installing a fabric connector" on page 1005).
• Hard disk drives and hard disk drive fillers (see "Installing a hot-swap hard disk drive" on page
1010).
• Hard disk drive cage and backplane assemblies (see "Installing the hard disk drive cage and
backplane assembly" on page 1008).
• I/O expansion adapters (see "Installing an I/O expansion adapter" on page 1011).
• Microprocessors and heat sinks. Use the microprocessor installation tool that comes with the
CRU kit to remove each microprocessor from the system board and install each one immediately
.
