Installing a microprocessor

IBM® xSeries 220: Installation Guide
Your server comes with one microprocessor, which is installed in microprocessor
connector U12 (the microprocessor connector that is closer to the power supply). This
is the startup (boot) microprocessor. If you install a microprocessor in microprocessor
connector U11, that one becomes the startup microprocessor, and the microprocessor
that is installed in microprocessor connector U12 is the application microprocessor.
You must also install a VRM when you install a microprocessor.
Notes:
1. The illustrations in this document might differ slightly from your server.
2. If necessary, see "System board option connectors" on page 4 for connector
locations.
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 clock frequencies
and external clock frequencies must be identical. See the ServerProven list at
http://www.ibm.com/pc/compat for a list of microprocessors for use with
your server.
• When you handle electrostatic discharge (ESD) sensitive devices, take
precautions to avoid damage from static electricity. For details on handling these
devices, see "Handling static sensitive devices" on page xi.
To install an additional microprocessor, do the following:
1. Review the safety precautions in "Safety" on page v.
2. Turn off the server and peripheral devices and disconnect all external cables and
power cords; then, remove the cover (see "Removing the side cover" on page 10
for details).
3. Carefully remove the support bracket assembly from the server (see "Removing
the support bracket assembly" on page 10). Store the cover and the support
bracket assembly in a safe place.
4. Lift the release lever on the microprocessor connector, and remove the terminator
card from the microprocessor connector.
5. Install the microprocessor:
a. Touch the static-protective package containing the new microprocessor to any
unpainted metal surface on the server; then, remove the microprocessor from
the package.
b. Orient the microprocessor over the microprocessor connector, as shown in the
following illustration. Carefully press the microprocessor into the connector.
