Before you begin
Notes:
1. This procedure should be performed only by trained service technicians.
2. The base assembly includes the chassis and system board.
Before you remove the base assembly, complete the following steps:
1. Read “Safety” on page v and “Installation guidelines” on page 487.
2. If the compute node is installed in an IBM Flex System chassis, remove it (see
“Removing a compute node from a chassis” on page 489 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 7917 and 2584,” on page 51):
v Alcohol wipes
v Bezel
v Thermal grease
About this task
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 23 for more
information.
See “System-board layouts” on page 16 for more information about the locations of
the connectors, jumpers, and LEDs on the system board.
Procedure
To remove the components from the system board, complete the following steps:
System-board
assembly
1. Remove the cover (see “Removing the compute node cover” on page 498).
2. Remove all of the installed components in the following list from the
system-board assembly; then, place them on a static-protective surface or install
them on the new system-board assembly.
v DIMMs and air baffles (see “Removing a DIMM” on page 501).
v I/O expansion adapters (see “Removing an I/O expansion adapter” on page
524).
