Installing the System Board

change the settings if necessary. See "System Board Jumpers" on page 115.

being careful to install the memory modules in the same locations.
See "Installing Memory Modules" on page 76.
4 Remove the processor from the original system board. See "Removing the Processor" on page 79.
5 Reinstall the processor and heat sink on the new system board. See "Installing a Processor" on page 81.

the chassis.
