Exchange the CEC enclosure system processor backplane assembly

Before you begin

Icon for electrostatic discharge wrist strapUse approved ESD procedures to prevent damage.

Attention:
  • This procedure is not a stand-alone procedure. Customer disruption and damage to the hardware might occur when microcode and power boundaries are not in the proper conditions for this service action.
  • If a serviceable event FRU repair directed you to this procedure, the microcode and power boundaries are already set.
  • If a serviceable event FRU repair did not direct you to this procedure, see MAP1230 Replace a FRU without using a serviceable event.
Notes:
  • All the cables and FRUs to be removed must be uniquely identified so they can be reinstalled correctly.
  • If an installed earthquake resistance kit prevents you from accessing this FRU, refer to MAP1600.

Remove the CEC enclosure system processor backplane assembly

Procedure

  1. Verify that the CEC enclosure is in the "power off" state before you continue. (The CEC enclosure should already be in the power off state.)
    Note: If this FRU has a FRU identify indicator LED, it is no longer lit.

    If you have not already located the FRU to be replaced, use the location code listed in the serviceable event FRU list. See MAP1245 Finding FRUs by using location codes.

  2. At the rear of the storage facility, view both CEC enclosure power supplies.
    Figure 1. CEC enclosure DC good LEDs

    Are both DC GOOD LEDs flashing?

  3. Remove all power from the CEC enclosure.
    • At the rear of the CEC enclosure, disconnect the power input cables Callout label A to both CEC enclosure power supplies.
    • At the CEC enclosure control panel, observe the green Power® Present icon, beneath the white Power button.
      • If it is slow flashing, the CEC enclosure is still in the power-off state. DO NOT CONTINUE. Ensure that you have unplugged the power cables.
      • If it is off, go to the next step.

  4. At the front of the CEC enclosure, remove the control panel by pressing the locking tabs Callout label A located on either side of the panel, grasping the edges of the panel, and pulling it out of its bay Callout label A.

  5. Remove all the system processor voltage cards:
    1. Squeeze the top of the latch to release it.
    2. Rotate the latch out and then down.
    3. Grasp the pull ring and slowly pull the system processor voltage card out of the enclosure.
    Attention: Pulling the system processor voltage card out of the card enclosure requires a large amount of force. The system processor voltage card is of substantial weight, so grasp it firmly when it is free of the card enclosure.

  6. Unlock the system processor backplane assembly Callout label A, and then pull it out of the CEC enclosure Callout label B using both hands.
    Attention: The system backplane assembly weighs 35 lb and should not be pulled out using the blue lever. Grasp the backplane assembly firmly with both hands when it is free of the system.

  7. Remove the service processor card assembly.
    1. Unscrew the two blue thumbscrews, pivot the processor alignment face plate out, and then remove it.

    2. Pull the locking knobs Callout label A out to the unlocked position.
    3. Push the locking arms Callout label B down and out to unlock the processor card assembly.
    4. Lift the processor card assembly Callout label C out of the system backplane assembly.

Install the CEC enclosure system processor backplane assembly

Procedure

  1. Place the system processor card assemblies into the system processor backplane assembly.
    1. Place the processor assembly into the system backplane assembly, and then lock it into place with the locking arms.
    2. Press the blue locking knobs in to the locked position.
    3. Install the processor alignment face plate, and then tighten the two blue thumbscrews.
  2. Carefully slide the system processor backplane assembly into the processor enclosure. Press it into place, and then lock it with the locking arm.
  3. Replace the system processor voltage cards:
    1. Ensure that the system processor voltage cards latch is rotated out to the unlocked position.
    2. Carefully grasp the system processor voltage cards and slide it into the enclosure.
    3. When the system processor voltage cards is almost all the way into the card enclosure, rotate the latch up into the locked position.
  4. Carefully slide the control panel into the control panel bay until you feel the locking tabs lock in place.
  5. At the rear of the CEC enclosure, connect the power input cables to both CEC enclosure power supplies.
  6. Ensure that the CEC enclosure is in the power-off state before you continue. At the CEC enclosure control panel, wait for the green Power Present icon, beneath the white Power button to slow blink, and then continue the repair.
  7. Exit this service information center parts exchange procedure and return to the procedure that sent you here.
