Use this information to replace a microprocessor.
The following notes describe the type of microprocessor
that the server supports and other information that you must consider
when you install a microprocessor and water loop:
Attention:
- Microprocessors are to be installed only by trained technicians.
- Do not allow the thermal grease on the microprocessor and water
loop to come in contact with anything. Contact with any surface can
compromise the thermal grease and the microprocessor socket.
- Dropping the microprocessor during installation or removal can
damage the contacts.
- Do not touch the microprocessor contacts; handle the microprocessor
by the edges only. Contaminants on the microprocessor contacts, such
as oil from your skin, can cause connection failures between the contacts
and the socket.
- The pins on the sockets are fragile. Any damage to the pins might
require replacing the system board.
Read the safety information in Safety and Installation guidelines.
If you are replacing a server component in the water-cooled technology tray, you need to remove the water-cooled technology tray from the chassis enclosure and refer to the Removing a water-cooled technology tray from a chassis and Installing a water-cooled technology tray in a chassis sections.
To install a microprocessor and water loop, complete the
following steps.
- Turn off the server and peripheral devices.
Attention: When you handle static-sensitive devices,
take precautions to avoid damage from static electricity.
- Remove the cover (see Removing the cover).
- Open the microprocessor socket release levers and retainer:
Figure 1. Microprocessor socket levers and retainer disengagement
- Identify which release lever is labeled as the first
release lever to open and open it.
- Open the second release lever on the microprocessor
socket.
- Open the microprocessor retainer.
Attention: Do not touch the connectors on the microprocessor
and the microprocessor socket.
- Remove the microprocessor socket cover,
tape, or label from the surface of the microprocessor socket, if one
is present. Store the socket cover in a safe place.

Attention: When you handle static-sensitive devices,
take precautions to avoid damage from static electricity.
- Close the microprocessor socket release levers and retainer:
Figure 3. Microprocessor socket levers and retainer engagement
- Close the microprocessor retainer on the microprocessor
socket.
- Identify which release lever is labeled as the first
release lever to close and close it.
- Close the second release lever on the microprocessor
socket.
Attention:
- If you are installing a new water loop, do not set down the water
loop after you remove the plastic covers.
- Do not touch the thermal grease on the bottom of the water loop.
Touching the thermal grease will contaminate it.
- Install the water loop on the planar tray
(see Replacing a copper water loop).
- Install the cross brace using M4 screw.
- Install the cover (see Replacing the cover).
- Slide the server into the rack.
- Reconnect any cables that you removed.
- Turn on the peripheral devices and the server.
