Removing the SAN Volume Controller 2145-CF8 system board

You must remove the system board if you are instructed to replace the SAN Volume Controller 2145-CF8 system board FRU.

DANGER
Multiple power cords. The product might be equipped with multiple power cords. To remove all hazardous voltages, disconnect all power cords.

You must remove and replace the microprocessor when you replace the system board. Ensure that you have alcohol wipes and thermal grease available to correctly perform this task.

Before you proceed with the system board removal, ensure that you do the following:
  • Have a static-protected surface available to hold the components that you remove from the old system board.
  • Follow all standard safety and handling instructions. The components that you will be handling are electrostatic-discharge sensitive. Take precautions to avoid damage from static electricity. Wear an anti-static wrist strap and use a static-protected mat or surface. For more information, see Handling static-sensitive devices.
This service action requires you to remove the cover and:
  • Turn the node off.
  • Disconnect the power cables.
  • Disconnect the data cables.
Notes:
  • You must remove a number of components before you can remove and replace the system board. You will reuse all the components with the new system board. Therefore, take care when you remove and store these components.
  • Each connector on the system board has its use printed next to it on the board.
  • All left or right observations are when you are looking at the front of the unit.

To remove the system board, perform the following steps:

  1. Read the safety information to which Preparing to remove and replace parts refers.
  2. Follow the procedure in MAP 5350: Powering off a SAN Volume Controller node to verify that the node data is mirrored and synchronized, and that there are no dependent virtual disks (VDisks) before turning off the node.
  3. Slide the node out on its slide rails to the fully extended position.
  4. When the node is completely turned off, remove the cable-retention brackets and disconnect the power cables, as described in Removing the cable-retention bracket.
  5. To make sure that you can replace all cables in the same ports from which they were removed, label the port position of each fibre-channel and Ethernet cable; then remove all cables from the back of the node.
  6. Optional: Remove the node from the rack and place it on a flat, static-protective surface. See Removing the SAN Volume Controller from a rack.

    You can perform most service actions when the node is fully extended from the rack on its slide rails. If the location of the node in the rack is too high or too low to work comfortably, you can remove the node from the rack.

  7. Remove the top cover. See Removing the top cover.
  8. Remove the fibre-channel adapter and riser-card assembly from slot 1. Set the adapter and riser card aside on the static-protected surface. See Removing the fibre-channel adapter assembly.
  9. Remove the high-speed SAS adapter and riser card assembly, if it is present, as described in Removing the SAN Volume Controller 2145-CF8 high-speed SAS adapter assembly.
  10. Remove the disk-controller and USB riser-card assembly, as described in Removing the SAN Volume Controller 2145-CF8 disk-controller and USB riser-card assembly.
  11. Remove the power supplies, as described in Removing a SAN Volume Controller 2145-CF8 power supply.
  12. Remove the microprocessor in slot 1, as described in Removing the SAN Volume Controller 2145-CF8 microprocessor; then remove the white plastic air baffles by lifting them straight up.
  13. Remove the memory modules and set them aside on a static-protective surface, as described in Removing the memory modules (DIMM).
    Note: Make a note of the location of each DIMM as you remove it, so that you can later reinstall it in the same connector.
  14. Disconnect all cables from the system board. Make a list of each cable as you disconnect it; you can then use this as a checklist when you install the new system board.
  15. Remove the hot-swap fans, as described in Removing the SAN Volume Controller 2145-CF8 fans.
  16. Press the fan bracket release latches (one is to the left of fan 6 and one is to the right of fan 1) inward toward the fans and rotate the fan assembly brackets up toward the front of the node.
  17. Grasp the system board handle ( 1  in Figure 1) and slide the system board away from the back of the node. Lift the side of the system board that is nearer to the power supply units slightly so that it disengages from the locator pin; then, slide the system board slightly toward the left of the node, as shown in Figure 1.

    Removing the system board from the SAN Volume Controller 2145-CF8 node
    •  1  System-board handle
    •  2  Fan-assembly bracket
  18. Lift up the system board and carefully remove it from the node, being careful not to damage any surrounding components.
  19. If you are instructed to return the system board, follow all packaging instructions, and use any packaging materials for shipping that are supplied to you.
