• If using Installation Tool A, gently twist the handle clockwise to the closed position and
lift the microprocessor out of the socket.
• If using Installation Tool B, gently twist the handle of the installation tool clockwise until it
locks in the “H” or “L” position, depending on the size of microprocessor; then, lift the
microprocessor out of the socket.

Step 13. If you are instructed to return the microprocessor, follow all packaging instructions, and use any
packaging materials for shipping that are supplied to you. Do not return the microprocessor
installation tool.
Replacing a microprocessor and heat sink
Use this information to replace a microprocessor and heat sink.
• 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 39.
• Be extremely careful when handling the microprocessor, the microprocessor socket contacts are very
fragile.
• Do not use any tools or sharp objects to lift the locking levers on the microprocessor socket. Doing so
might result in permanent damage to the system board.
• Each microprocessor socket must always contain either a socket cover or a microprocessor and heat sink.
• When replacing multiple microprocessors, open one microprocessor socket at a time to avoid damaging
other microprocessor socket contacts.
• Be sure to use only the installation tools provided with the new microprocessor to remove or install
the microprocessor. Do not use any other tool.
• The microprocessor installation tool has the microprocessor installed on the tool, and may have a
protective cover over the microprocessor. Do not use the tool, or remove the cover until you are
instructed to do so.
Notes:
• See “Installing an additional microprocessor and heat sink” on page 91 for notes and other information
that you must consider when you install a microprocessor.
• The server supports up to four Intel Xeon dual-core or quad-core microprocessors (two on the
base system board and two on the optional microprocessor and memory expansion tray). See
http://www.ibm.com/systems/info/x86servers/serverproven/compat/us/ for a list of supported
microprocessors.
• Be sure to only install microprocessors that have the same speed, number of cores, and frequency.
• This procedure for replacing a microprocessor and heat sink also apply when replacing a microprocessor
and heat sink on the microprocessor and memory expansion tray.
