The installation tool has two settings for installing two different sizes of
microprocessors. The settings that are marked on tool are "L" for smaller low core
microprocessors, and "H" for larger high core microprocessors. Installation tool
supports the following families of microprocessors: E5-26xx, E5-46xx, E5-26xx v2,
E5-46xx v2.
To replace a microprocessor and heat sink, complete the following steps:

removed from the heat sink, do not touch the thermal grease on the bottom of
the heat sink or set down the heat sink. For more information about applying or
working with thermal grease, see "Thermal grease" on page 175.
Note: Removing the heat sink from the microprocessor destroys the even
distribution of the thermal grease and requires replacing the thermal grease.

1. Read the safety information that begins on "Safety" on page vii and
"Installation guidelines" on page 93.
2. Turn off the server and peripheral devices and disconnect the power cords
and all external cables.
Attention: When you handle static-sensitive devices, take precautions to
avoid damage from static electricity. For details about handling these devices,
see "Handling static-sensitive devices" on page 95.
3. Remove the cover (see "Removing the compute node cover" on page 110).
4. Remove the air baffle (see "Removing the air baffle" on page 113).
5. Loosen the four screws on the corners of the microprocessor retainer.
6. Open the microprocessor socket release levers and retainer:
a. Identify which release lever is labeled as the first release lever to open and
open it.
b. Open the second release lever on the microprocessor socket.
c. Open the microprocessor retainer.
Attention: Do not touch the connectors on the microprocessor and the
microprocessor socket.
7. Install the microprocessor in the microprocessor socket:
