processor boards, as shown in the following illustration. Your
server comes with a microprocessor preinstalled in the primary
socket. Therefore, you will install the new microprocessor in the
secondary socket (also known as an upgrade socket).
Note: Both microprocessors on a processor board must have the
same speed to ensure proper server operation.
