SMP Expansion board replacement
Complete the following steps to replace an SMP board.
Note:
v Read “Installation guidelines” on page 71.
v Read the safety notices at “Safety notices (multi-lingual translations)” on
page 205.
v Read “Handling electrostatic discharge-sensitive devices” on page 204.
1. Turn off the server (see “Turning off the server” on page 11) and disconnect all
power cords and external cables.
2. Open the cover (see “Opening the cover” on page 72).
3. Remove the SMP module(s) and cover from which the SMP board will be
replaced (see “Removing an SMP Expansion Module and cover” on page 87).
4. Set the SMP module on a static-free, clean work surface and remove the
components in the module that will be reused:
v Memory (see “DIMM removal and replacement” on page 93).
v
Microprocessor assemblies and VRMs (see “Microprocessors” on page 95).
5. Install the components that were removed in the preceding step into the new
board.
6. Reinstall the SMP cover, and reinstall the module in the server (see
“Reinstalling an SMP Expansion Module and cover” on page 101).
Note: When you install or remove SMP Expansion Modules, the server
configuration information changes. Therefore, you must change and save
FRU information (service only)
