You need to remove the microprocessor before you replace
it.
Before you begin
DANGER
Multiple power cords. The product might be equipped with multiple
power cords. To remove all hazardous voltages, disconnect all power cords. (L003)
About this task
This procedure is based on the following assumptions:
- You are a trained IBM® service technician.
- You removed all power from the node.
- You removed the node from the rack.
- You removed the top cover of the node.
Attention: Removing the heat sink from the microprocessor
also removes the even distribution of the thermal grease and requires
removing the thermal grease.
If the thermal-grease protective cover (for example,
a plastic cap or tape liner) is removed from the heat sink, do not
touch the thermal grease on the bottom of the heat sink or set down
the heat sink.
Procedure
Remove the heat sink, as shown in Figure 1.
- Open the heat sink retention module release lever to the
fully open position.
Figure 1. Removing the heat sink
- Lift the heat sink out of the server. After removal, place
the heat sink (with the thermal grease side up) on a clean, flat surface.
Open the microprocessor socket release levers and retainer,
as shown in Figure 2.
Figure 2. Opening the release
levers
- 1 microprocessor release lever
- 2 microprocessor release lever
- 3 microprocessor retainer
- Open the first release lever ( 1 ) on the microprocessor socket.
- Open the second release lever ( 2 ) on the microprocessor socket.
- Open the microprocessor retainer ( 3 ).
Attention: Do not touch the microprocessor
contacts. Contaminants on the microprocessor contacts, such as oil
from your skin, can cause connection failures between the contacts
and the socket.
Remove the microprocessor from the socket, as shown in Figure 3.
Figure 3. Removing the microprocessor with the installation tool
- Twist the microprocessor installation tool handle counterclockwise
to the open position.
- Align the installation tool with the alignment pins on
the microprocessor, and lower the installation tool on the microprocessor.
The installation tool rests flush on the socket only when it is aligned
correctly.
- Gently twist the handle clockwise to the closed position
and lift the microprocessor out of the socket.
Note: The
pins on the socket are fragile. Any damage to the pins might require
replacing the system board.
- If you are instructed to return the microprocessor, follow
all packaging instructions, and use any packaging materials for shipping
that are supplied to you.
