DS8000 Service Documentation Version 7.5

Exchange the CEC enclosure VPD pass-through card

Before you begin

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

Attention:
  • This is not a stand-alone procedure. Customer disruption and damage to the hardware might occur if microcode and power boundaries are not in the proper conditions for this service action.
  • If you were sent here by a serviceable event FRU repair, the microcode and power boundaries have already been set.
  • If you were not sent here by a serviceable event FRU repair, 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 VPD pass-through card

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

    CEC enclosure DC good LEDs

    Are both DC GOOD LEDs flashing?

  3. Use a replacement part with a valid DS8000® part number to ensure the DS8000-unique firmware is already installed and configured.

    Attempting to use a generic part from an eServer™ will fail and complicate the repair.

  4. 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.

Install the CEC enclosure VPD pass-through card

About this task

Note: This procedure shows a VPD pass-through card with two Ethernet ports. Some CEC enclosures have a VPD pass-through card with four Ethernet ports. In this product, they are functionally equivalent, and the exchange procedure is the same.

Procedure

  1. Install the CEC enclosure VPD pass-through card.
    1. Note the metal tab on the top edge of the pass-through card.
    2. Insert the card into the connector on the I/O backplane ensuring that the metal tab engages the slot on the top edge of the shroud for the power supplies.
      Attention: If the tab does not engage the slot in the shroud, the pass-through card will not connect securely and damage to the pins on the connector could occur.
  2. At the rear of the CEC enclosure, carefully slide the I/O backplane assembly into the CEC enclosure.
  3. At the front of the CEC enclosure, tighten the two thumbscrews to fasten the I/O backplane assembly into the CEC enclosure.
  4. Carefully slide the system processor backplane assembly into the CEC enclosure. Press it into place, and then lock it with the locking arm.
  5. Install the system processor voltage cards.
    1. Ensure that the system processor voltage card latch is rotated out to the unlocked position.
    2. Carefully grasp the system processor voltage card and slide it into the enclosure.
    3. When the system processor voltage card is almost all the way into the card enclosure, rotate the latch up into the locked position.
  6. Install the disk drive enclosure.
    1. Carefully slide the CEC disk drive enclosure into the CEC enclosure until you feel it lock into place.
    2. Close the handles to secure it into the proper position.
  7. Push both CEC enclosure fans all the way into the fan slots, and then lift the attached rings up to lock the fans into place.
  8. Install the removable media device enclosure filler.
    1. Pivot the CEC enclosure fan orange pull rings up out of the way.
    2. Gently slide the removable media device enclosure filler into place.
    3. Push the two orange locking knobs into the locked position.
  9. Gently slide the control panel into place and ensure the locking tabs on both sides of the control panel lock into place
  10. At the rear of the CEC enclosure, install both power supplies.
    1. Push the power supply in place.
    2. Close the locking handle.
  11. Install the VPD card with the key oriented to the right and push until fully seated.
  12. Install the service processor card.
    1. Ensure that the service processor card handle is rotated to the down position.
    2. Slide the service processor assembly all the way into the card slot in the system enclosure.
    3. Push the handle toward the service processor assembly until the release tab locks the handle in place. This will secure the service processor assembly into the card slot.
  13. Install the PCIe four port card or filler into slot 9.
    1. With the latch in the down position, slide the card in to the enclosure.
    2. When it stops, raise the latch to the vertical position.
    3. Install the latch screw.
  14. Install the CEC enclosure RIO card into slot 8.
    1. With the latch in the down position, slide the card in to the enclosure.
    2. When it stops, raise the latch to the vertical position.
    3. Install the latch screw.
  15. Install the PCIe cassettes in slots 1 through 5. Ensure that the PCIe cassettes with adapter cards are in their original slots.
    1. Ensure that the lower cassette handle of the FRU is pressed up toward the retainer clip. This places the adapter in the correct position to be docked in the system.
    2. Lift and hold the PCIe adapter EMC shield in the open position.
    3. Slide the cassette into the cassette slot, as shown in Figure 18.
      Figure 18. Installing PCIe adapter cards
      Installing PCIe adapter cards
    4. When the cassette is fully inserted into the system, firmly press downward on the lower cassette handle to lock the adapter in its connector.
    5. Lower the PCIe adapter EMC shield into the closed position and then slide the lift tab down to secure it.
  16. Connect all the cables except the power supply input cables.
  17. Connect the power input cables to both CEC enclosure power supplies.
  18. Ensure that the CEC enclosure is in power off state before continuing. At the CEC enclosure control panel, wait for the green Power Present Icon beneath the white Power button to slow blink.
  19. Exit this service information center parts exchange procedure and return to the procedure that sent you here.
