Removing the microprocessor: 2145-DH8

Edit online

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)
Multiple plugs: first set
 or
Multiple plugs: second set
 or
Multiple plugs: third set

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.

  1. Open the heat sink retention module release lever to the fully open position.

  2. 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.

Opening the release levers
  •  1  microprocessor release lever
  •  2  microprocessor release lever
  •  3  microprocessor retainer

  1. Open the first release lever ( 1 ) on the microprocessor socket.
  2. Open the second release lever ( 2 ) on the microprocessor socket.
  3. 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.

Removing the microprocessor with the installation tool

  1. Twist the microprocessor installation tool handle counterclockwise to the open position.
  2. 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.
  3. 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.
  4. If you are instructed to return the microprocessor, follow all packaging instructions, and use any packaging materials for shipping that are supplied to you.
