How to Replace the Power Supply Backplane in an Oracle Exalytics X2-4 or X3-4 system

Solution

CAP PROBLEM OVERVIEW: Power Supply Backplane replacement

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:
Oracle Exalytics Server Training.

TIME ESTIMATE: 90 minutes

TASK COMPLEXITY: 4-FRU

FIELD ENGINEER INSTRUCTIONS

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :

If the system is still up and functioning, the customer should perform an orderly and graceful shutdown of applications and OS.

A data backup is not a prerequisite but is a wise precaution.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1. Prepare the server for service.

1. Power off the server and disconnect the power cords from the power supplies.
2. Extend the server to the maintenance position in the rack.
3. Attach an anti-static wrist strap.
4. Remove the top cover.

2. Remove Power Supplies

1. Press down on the release latch and rotate it forward/down to disengage the power supply from the server.
2. Pull both power supplies at least part way out of the chassis, to disconnect them from the power supply backplane.

3. Remove all memory risers

1. For each of the memory risers lift them straight up to remove them from the memory module socket.
2. set each memory riser aside on an antistatic mat. Attention to the removal order should be taken so that the modules can be replaced in the same locations from which they were removed.

4. Remove the installed PCIe cards.

1. The server has ten PCIe slots.They are numbered 0 through 9 from left to right when you view the server from the rear (the onboard ports/connectors are located between slots 4 and 5)
2. Make a note of the slots where the PCIe cards are installed so that they can be re-installed in the same locations.
3. Unplug any data cables from the PCIe cards making note of the locations so that they can be re-installed in the same configuration (label if needed).
4. Disengage the PCIe slot crossbar from it's locked position and rotate it into it's upright position.
5. Carefully remove the PCIe cards from their slots by lifting straight up from the connectors.
6. Place each of the PCIe cards aside on an antistatic mat.

Note: The Exalytics X2-4 and X3-4 systems use a very specific PCIe configuration and the cards must be populated correctly to operate properly. Care should be taken to make sure that PCIe cards are replaced back into their original/correct slots when any service is performed.

5. Remove the Motherboard then the Power Supply Backplane

1. Remove the air divider by pulling it up and out of the chassis.
2. Remove the ribbon cable connecting the power supply backplane to the motherboard.
3. Remove the screw holding the power supply cover in place and remove the power supply cover.
4. Remove the motherboard, Loosen the green captive screw in the corner near the fans that secures the motherboard to the chassis.
5. Disconnect all cables that connect the power supply backplane, disk drive backplane, and fan board to the motherboard.
6. Remove the four bus bar screws securing the motherboard to the power supply backplane.
7. Position the cables off to the side.
8. Grasp the handle on the motherboard and slide it toward the front and then out of the chassis.
9. place the motherboard aside on an antistatic mat.
10. Disconnect the AC cables from power supply backplane.
11. Lift the power supply backplane out of the chassis
12. place the power supply backplane aside on an antistatic mat.

6. Install the new Power Supply Backplane and re-install the motherboard

1. Unpack the replacement power supply backplane and place it on an antistatic mat.
2. Hold the power supply backplane at the end of the power supply cage and connect the AC cables to the AC connectors on the power supply backplane. Ensure that each AC cable is connected to the appropriate connector. The AC cable on the right must be connected to the AC connector on the right and the AC cable on the left must be connected to the AC connector on the left.
3. Insert the power supply backplane into position by ensuring that the tabs on the power board slide onto the hooks on the power supply cage.
4. Re-install the motherboard. Grasp the motherboard by the handle and hold the cables off to the side while sliding the motherboard toward the back of the chassis.
5. Align the rear Locate button with its corresponding hole in the back of the chassis, and ensure that the Locate button is not jammed in the down position.
6. Tighten the captive screw in the corner near the fans that secures the motherboard to the chassis.
7. Reinsert and tighten the four bus bar screws that secure the motherboard to the power supply backplane.
8. Reinstall the air divider by sliding it into the chassis.
9. Reconnect all cables from the power supply backplane, disk drive backplane, and fan board to the motherboard.
10. Reinstall the power supply cover plate that secures the SAS cables.

7. Reinstall the Power Supplies

1. Slide each of the power supplies back into their bays until fully seated.
2. Move the release latch up to secure the power supplies in place.

7. Reinstall all memory risers.

1. Align each memory riser with it's riser slot on the motherboard.
2. Push each memory riser module into it's associated CPU memory riser slot until the riser module locks in place.

8. Reinstall all PCIe cards.

1. Make sure to re-install the cards into the exact same locations from which they were removed.
2. For each of the cards return the PCIe card slot crossbars to their closed and locked position to secure the PCIe cards in place.
3. Reconnect any cables to the PCIe cards that were unplugged during the removal procedure making sure to connect them in the same configuration as when they were disconnected.

9. Return the Server to operation

1. Replace the top cover
2. Remove any anti-static measures that were used.
3. Return the server to it's normal operating position within the rack.
4. Re-install the AC power cords and any data cables that were removed.
5. Power on server. Verify that the Power/OK indicator led lights steady on.
6. Allow the system to power up and confirm it functions properly.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

Boot up system and verify full functionality
