Attention: v 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 the server. v 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 114. Installing a microprocessor To install an additional microprocessor, do the following: 1. Review the safety precautions in Statement 1 and Statement 5 in "Safety information" on page 111. 2. Turn off the server and all attached devices, disconnect all power cords and then all external cables; then, remove the cover (see "Removing the side cover" on page 45 for details). 3. Carefully remove the support bracket assembly (see "Removing the support bracket assembly" on page 47). Store the cover and the support bracket assembly it in a safe place. 4. Lift the release lever 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.

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 the

Installing a microprocessor
To install an additional microprocessor, do the following:
1.
Review the safety precautions in Statement 1 and Statement 5 in
“
Safety
information
”
on page 111.
2.
Turn off the server and all attached devices, disconnect all power cords and
then all external cables; then, remove the cover (see
“
Removing the side
cover
”
on page 45 for details).
3.
Carefully remove the support bracket assembly (see
“
Removing the support
bracket assembly
”
on page 47). Store the cover and the support bracket
assembly it in a safe place.
4.
Lift the release lever 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.
