ESD Caution:

Circuit boards and drives contain electronic components that are extremely sensitive to static electricity. Ordinary amounts of static electricity from clothing or the work environment can destroy the components located on these boards. Do not touch the components along their connector edges.
Use a Antistatic Wrist strap. Attach one end of the strap to your wrist and the other end to the chassis, depending on what type of strap you use, with the adhesive end or the metal plug.
Use an Antistatic Mat. Place ESD-sensitive components such as motherboards, memory, and other PCBs on an antistatic mat.

Contamination Caution:

Dust particles of packaging material are number one cause of datacenter contamination. Make sure to remove all packaging material, up to the ESD safe packaging material, while still being outside the datacenter.

FIELD ENGINEER INSTRUCTIONS

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? : Clock board must be prepared for removal via ILOM commands.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1. Poweroff the faulty Clock Board (-> stop /SYS/CLOCKx) where x = 0 or 1

if ILOM responds with "stop: Target already stopped" or "Stopping /SYS/CLOCKx" proceed to Step 3
if ILOM responds with any other output the target clock board is the active clock board. Proceed to Step 2.

2. This step is necessary ONLY if the target Clock Board is currently active

stop all PDomains (-> stop /System)

3. Prepare the Clock Board for removal (blue ready to remove LED should light during this step):

set the prepare to remove property (-> set /SYS/CLOCKx prepare_to_remove_action=true) where x = 0 or 1

4. Use a grounding strap to protect the equipment from ESD damage.

5. Locate the Faulty Clock Board at the front of the chassis.

6. Remove the Faulty Clock Board (blue ready to remove LED must be lit to remove the board):

Use a T20 Torx screwdriver to loosen two captive screws.
Open the extraction levers fully to unseat the Clock Board.
Pull the Clock Board out of the cabinet.

7. Unpack the replacement Clock Board from its ESD safe packaging.

8. Pack the faulty Clock Board into its ESD safe packaging.

9. Install the replacement Clock Board:

Open the extraction levers fully.
Insert the replacement Clock Board until the extraction levers start to close.
Close the extraction levers to lock the Clock Board in the slot.
Use a T20 Torx screwdriver to tighten the two captive screws.

10. Verify correct properties on the replacement Clock Board:

-> show -d properties /SYS/CLOCKx where x = 0 or 1

        requested_config_state = Enabled
        current_config_state = Enabled
        disable_reason = None
        fault_state = OK

Properties should match the above. If, for example, current_config_state is Disabled and disable_reason is 'By User', you must re-enable the clock board.

-> set /SYS/CLOCKx requested_config_state=Enabled where x = 0 or 1

11. Start the replaced Clock Board (-> start /SYS/CLOCKx) where x = 0 or 1

12. If the PDomains are stopped, restart them (-> start /System)

13. Prepare the faulted Clock Board outside the datacenter for return to Oracle.

OBTAIN CUSTOMER ACCEPTANCE

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

Restart software applications per applicable administration guides to resume system operation.
