2. Obtain an SMP-capable operating system (optional). For a list of supported
operating systems, see http://www.ibm.com/pc/us/compat/ on the World Wide
Web.
3. If two microprocessors are installed, the microprocessor installed in connector
U69 is the startup processor, and the microprocessor installed in U68 is the
application processor.
Attention: To avoid damage and ensure proper server operation when you install a
new or 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.
Note: Mixing stepping levels in a system can result in intermittent misbehavior such
as various system stalls, blue screens, and boot failure.
To install an additional microprocessor:
1. Review the information in “Before you begin” on page 35, “Safety information” on
page 37, and “Handling static-sensitive devices” on page 36.
2. Turn off the server and peripheral devices and disconnect all external cables and
power cords; then, remove the cover (see “Removing the cover and bezel” on
page 43).
3. Remove the fan 3 assembly by lifting the orange handle on top of the fan
assembly and pulling the fan assembly away from the server.
