Installing the second microprocessor
Attention: Do not open your server or attempt any repair before reading and understanding "Safety information"
on page iii and "Guidelines" on page 67.
Depending on the model, your server might come with one or two microprocessors. For server 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. You can purchase a microprocessor option kit from Lenovo
and install the second microprocessor to expand system capabilities.
CAUTION:
Turn off the server and wait several minutes to let the server cool before removing the server cover.
Before you begin, print all the related instructions or ensure that you can view the PDF version on another
computer for reference.
Notes:
• Ensure that you install the correct type of microprocessor option your server supports. See "Features" on
page 7. When two microprocessors are installed, both must have the same core voltage and core speed.
• Use any documentation that comes with the microprocessor option kit and follow those instructions in
addition to the instructions in this topic.
• 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. Remove all external media from the drives and turn off all attached devices and the server. Then,
disconnect all power cords from electrical outlets and disconnect all cables that are connected to
the server.
2. Prepare your server. See "Removing or extending the server from the rack cabinet" on page 69.
3. Remove the server cover. See "Removing the server cover" on page 69.
4. Remove the cooling shroud. See "Removing and reinstalling the cooling shroud" on page 72.
5. Locate the microprocessor socket 2 on the system board. See "System board components" on page 44.
