Removing a CPU

Removing a CPU

Procedure

  1. Power off the G560 V5. For details, see Powering Off the Compute Node.
  2. Remove the G560 V5. For details, see Removing the G560 V5.
  3. Place the G560 V5 on the ESD floor.
  4. Remove the cover. For details, see Removing the Cover of the G560 V5.
  5. Determine the CPU to be removed. Figure 5-56 shows the numbering and locations of CPUs.

    Figure 5-56 Numbering and locations of CPUs

  6. Remove a heat sink.

    Use a T20 Torx screwdriver to loosen the two middle screws (corresponding to 2 on the heat sink label) on the heat sink. See (1) in Figure 5-57. Then loosen the two diagonal screws (corresponding to 1 on the heat sink label). See (2) in Figure 5-57.

  7. Lift the heat sink away and place it upside down on a desk.
  8. Insert a flat-head screwdriver into the release slot of the CPU carrier and twist the screwdriver to raise one edge of the carrier. See (3) in Figure 5-58.

  9. Pinch the retain clip on the other edge. See (4) in Figure 5-58. Lift the carrier with the CPU inside upwards in the direction of the arrow. See (5) in Figure 5-58.
  10. Bend the installation tool edge with a triangular hole to release the CPU from the installation tool. See Figure 5-59.

    NOTE:

    When removing the CPU, hold the CPU and CPU installation tool to prevent them from falling.

    Figure 5-59 Removing a CPU (1)

  11. Holding both sides of the CPU, lift it upwards. See Figure 5-60.

  12. Clean up the thermal compound on the CPU surface and place it in an ESD bag.

    NOTE:

    Ensure that CPU sockets are populated with CPUs or CPU socket covers during transportation and storage.

  13. (Optional) If you do not install a CPU immediately, install a CPU protective cover in the socket. The cover is installed successfully when you hear a click.
