Separating the 571F/575B card set and moving the cache directory card

To complete this procedure, you will need a T-10 TORX bit or driver.

Attention: To avoid loss of cache data, you must not remove the cache battery during this procedure.

To separate the 571F/575B card set and move the cache directory card, do the following:

Important:
All cards are sensitive to electrostatic discharge.
  1. Label both sides of the card before separating.
  2. Go to the next step if you are not servicing a 571F/575B card set containing a light pipe assembly. If you are servicing a 571F/575B card set that contains a light pipe assembly, you will need to remove the light pipes. To remove the light pipes, do the following:
    1. Place the 571F/575B card set adapter on an ESD protective surface.
    2. Remove the light pipe retaining screw C from the 571F/575B card set.
    3. Slide the light pipe assembly D from between the 571F/575B cards.
    4. Put both the screw and the light pipe assembly in a safe place.

  4. Disconnect battery cable A and SCSI cable B from the 571F storage adapter. Leave the other end of the cables attached to the 575B auxiliary cache adapter.

  5. To prevent possible card damage, first loosen all 5 retaining screws C BEFORE removing them. After all five retaining screws have been loosened, remove the screws C from the 571F storage adapter.

  7. Turn the 571F storage adapter over so the components are facing up and locate the cache directory card D on the 571F storage adapter. It is the small rectangular card mounted on the I/O card.

  8. Unseat the connector on the cache directory card by wiggling the two corners that are farthest from the mounting pegs. To disengage the mounting pegs, pivot the cache directory card back over the mounting peg.

  9. Move the cache directory card to the replacement 571F storage adapter and seat it on the connector and mounting pegs.
  10. To reassemble the cards do the above procedure in reverse order. To prevent possible card damage, insert all 5 screws C before tightening any of them.
    Note:
    If you are installing the 571F/575B card set adapter into a cassette, do the following:
    1. Remove the adapter handle B as shown in the following illustration.
    2. If applicable, remove the light-pipe assembly.
    3. Remove the two plastic covers from the SCSI jumper cable A as shown in the following figure:

    4. Ensure that battery cable A and SCSI cable B are reconnected to the 575B auxiliary cache adapter.
    5. Go to Place an adapter in the PCI adapter double-wide cassette to complete the installation.
  11. If applicable, to replace the light pipes, do the following:
    1. Ensure that the 571F/575B cards are correctly assembled.
    2. If necessary, remove the 571F/575B card handle A from the back of the card set.
      Tip:
      If you misplace the light-pipe retaining screw C, use either of the screws that secure the card handle B to the card.
    3. Slide the light pipe assembly D between the 571F/575B cards. Ensure that the threaded screw hole located on the light pipe assembly is aligned with the screw clearance hole located on the card .
