Intel Server Board STL2 Motherboard

Processors

WARNING

If the server has been running, any installed processor and heat sink on the processor board(s) will be hot. To avoid the possibility of a burn, be careful when removing or installing server board components that are located near processors.

CAUTIONS

Processor must be appropriate:

You may damage the server if you install a processor that is inappropriate for your server. Make sure your server can handle a newer, faster processor (thermal and power considerations). For exact information about processor interchangeability, contact your customer service representative or visit the Intel Customer

Support website:

http://support.intel.com/support/motherboards/server/STL2

ESD and handling processors:

Reduce the risk of electrostatic discharge (ESD) damage to the processor by doing the following: (1) Touch the metal chassis before touching the processor or server board. Keep part of your body in contact with the metal chassis to dissipate the static charge while handling the processor. (2) Avoid moving around unnecessarily.

Adding or Replacing a Processor

If you are adding a second processor to your system, you must first remove the terminator from the secondary processor socket. The second processor must be compatible with the first processor

(within one stepping, same voltage, same speed, see the Intel support website for specifics).

1.

Observe the safety and ESD precautions at the beginning of this chapter and the additional cautions given here.

2.

Remove the side cover (see your system or chassis documentation for instructions).

3.

Raise the locking bar on the socket.

4.

Aligning the pins of the processor with the socket, insert the processor into the socket. Note what the processor speed is so you can set the jumpers correctly.

Removing a Processor

1.

Observe the safety and ESD precautions at the beginning of this chapter and the additional cautions given here.

2.

Unplug the heatsink fan.

3.

Detach the heatsink clip from the processor socket. See the documentation that shipped with your processor for more detail.

4.

Remove the heatsink from the processor.

5.

Raise the locking bar on the socket.

6.

Remove the processor from the socket.

7.

If you removed the processor from the secondary socket and are not replacing it, you must install a terminator in its place.

Installing or Removing a Terminator

1.

Observe the safety and ESD precautions at the beginning of this chapter and the additional cautions given here.

2.

Raise the locking bar on the socket.

3.

Aligning the pins of the processor terminator with the socket, insert the terminator into the socket.

4.

Lower the locking bar completely.

Do these steps in reverse to remove the terminator.
