Install a Processor

  • Use an antistatic wrist strap and a work space with an antistatic mat.

    See Electrostatic Discharge Safety.

  • Use ESD gloves, if possible, when handling the processor (not latex or vinyl).

  • Be careful not to touch the processor socket pins.

    Caution:

    The processor socket pins are very fragile. A light touch can bend the processor socket pins beyond repair.

  • Obtain a preset or adjustable torque driver set to 8 in-lbf (inch-pound force) with a T30 Torx bit.

    Caution:

    Using an incorrect torque setting or driver can damage a processor-heatsink module.

  • If you are replacing a processor, ensure that the replacement processor is identical to the processor that was removed. For a list of supported processors, see Product Description.

  1. Use the syringe supplied with the new or replacement processor [1] to apply all of thermal interface material (TIM) in an "X" pattern to the processor contact area of the heatsink [2].

    Figure showing thermal grease being applied to the heatsink.

    Note:

    Do not distribute the TIM; the pressure of the heatsink will do so for you when you install the heatsink.
  2. Install the new processor.
    1. Open the box that contains the new processor but do not remove it from its ESD-safe packaging tray.

      Note:

      The processor carrier has latching tabs at each corner that attach to the edge of the heatsink.
    2. Place the heatsink (TIM adhesive side down) onto the processor carrier until the latch tabs at each corner of the processor carrier attach to the heatsink [1].

      Note:

      There is a die-cut triangle in the processor carrier that points to the pin 1 corner of the processor.

      Figure showing the heatsink being attached to processor/processor carrier.
    3. Lift the assembled processor-heatsink module out of the packaging tray.

      Figure showing the processor-heatsink module being lifted from packaging tray.
    4. Align the processor-heatsink module with the processor socket bolster plate on the motherboard by matching up the pin 1 corner of the processor (indicated by a gold triangle on the underside of the processor [2]) with the pin 1 corner (indicated by an etched triangle) of the bolster plate [1].

      Figure showing the socket with callout to Pin 1.
    5. Carefully, place the processor-heatsink module on the socket bolster plate on the motherboard. The bolster plate has four threaded posts at each corner to ensure correct alignment.

      Figure showing the processor-heatsink module being lowered onto the socket.
    6. Pivot the anti-tilt wire around each of the four captive heatsink load nuts to the locked position [1] (away from the heatsink), engaging the wire with the lock tab on the bolster plate [2].

      Figure showing the processor-heatsink module anti-tilt wires set to the locked position.
    7. Using a torque driver adjusted to 8 in-lbf with a Torx T30 bit, tighten the four processor heatsink captive load nuts. The nuts can be tightened in any order.
  3. Return the server to operation.
    1. Install the air baffle.
    2. Install the server top cover.
    3. Return the server to the normal rack position.
    4. Reconnect the power cords to the power supplies, and power on the server.
    5. Verify that the power supply AC OK LED is lit.
  4. Use Oracle ILOM to clear server processor faults.
    1. To show server faults, log in to Oracle ILOM as root. Using the Oracle ILOM CLI, type the following command to list all known faults on the server:

      -> show /SP/faultmgmt

      The server lists all known faults, for example:

      -> show /SP/faultmgmt
  Targets:
      shell
      0 (/SYS/MB/P0)
  Properties:
  Commands:
      cd
      show

      Alternatively, log in to the Oracle ILOM service processor from the Oracle ILOM Fault Management Shell and issue the fmadm faulty command. For more information about how to use the Oracle ILOM Fault Management Shell and supported commands, see the Oracle ILOM User's Guide for System Monitoring and Diagnostics in the Oracle Integrated Lights Out Manager (ILOM) 5.1 documentation at Servers Documentation - Systems Management.

    2. To clear the fault, type the following command:

      -> set /SYS/MB/P0 clear_fault_action=true

      For example:

      -> set /SYS/MB/P0 clear_fault_action=true
Are you sure you want to clear /SYS/MB/P0 (y/n)? y
Set ‘clear_fault_action’ to ‘true’

      For more information about how to use the Oracle ILOM Fault Management Shell and supported commands, see the Oracle ILOM User's Guide for System Monitoring and Diagnostics in the Oracle Integrated Lights Out Manager (ILOM) 5.1 documentation at Servers Documentation - Systems Management.
