This topic provides instructions on how to install the second microprocessor.
Depending on the model, your computer might come with one or two microprocessors. For computer
models with one microprocessor, the microprocessor is installed in the microprocessor socket 1 and the
microprocessor socket 2 is protected by a plastic socket cover.
CAUTION:
The heat sink and microprocessor might be very hot. Before you open the computer cover, turn off
the computer and wait several minutes until the computer is cool.
Notes:
• Ensure that you install the correct type of microprocessor option your computer supports. When two
microprocessors are installed, both must be identical.
• For E5-1600 v4 series microprocessors, the computer can support only one installed. If you want to install
two microprocessors into your computer, use the E5-2600 v4 series microprocessors.
• A second heat sink and fan assembly is also required. Ensure that you have this assembly available
before you start the installation.
• Your microprocessor, socket, and socket cover might look slightly different from the illustrations in this
topic.
To install the second microprocessor, do the following:
1. Prepare your computer. See "Preparing your computer and removing the computer cover" on page 101.
2. Remove the direct cooling air baffle. See "Direct cooling air baffle" on page 105.
3. Lay the computer on its side for easier access to the system board.
4. Locate the microprocessor socket 2 on the system board. See "Parts on the system board" on page 35.
