To ensure proper server operation when you install an additional microprocessor,
use microprocessors that have the same cache size and type, and the same
clock speed. Microprocessor internal and external clock frequencies must be
identical.
Complete the following steps to install an additional microprocessor:
1. Read the safety information beginning on page v, and “Installation guidelines” on
page 11.
2. Turn off the server and disconnect all power cords and external cables (see
“Turning off the server” on page 13); then, remove the server cover (see
“Removing the cover and bezel” on page 15).
3. Remove the air baffle covering the microprocessor section of the system board
and set the air baffle aside.
