Lenovo ThinkServer TD340 - Manual (Page 179)

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 the new microprocessor is the correct type your server supports. See “Memory module
installation rules” on page 93. 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 replace the microprocessor, do the following:
1. Remove all 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. Remove the server cover. See “Removing the server cover” on page 85.
3. Lay the server on its side for easier operation.
4. Remove the heat sink and fan assembly. See “Replacing the heat sink and fan assembly 1” on page 193.
5. Locate the microprocessor socket, press down the small handle on the microprocessor socket, and
then pull the handle a little bit outward to release it from the secured position. Then, gently press
the microprocessor retainer to open it. Ensure that the small handle and the microprocessor retainer
are in the fully open position.
