TIME ESTIMATE: 75 minutes

TASK COMPLEXITY: 3

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: An Oracle Server X5-4 Motherboard needs replacement

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

Shut down system and Power down the server.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1. Positioning the Server for Maintenance

2. Removing the Server Top Cover

3. Remove the SP Card.

4. Remove the Motherboard

•  Remove all PCIe cards from the server taking care to note their slot assignments and cable routing.
•  Remove the air baffle taking care not to damage the fan board ribbon cable if this is a 2 CPU configuration.
  
  • [Caution -the fan board ribbon cable can be damaged if baffle is lifted straight up.]
•  Remove all memory riser cards.
•  Disconnect the fan board power and data cables from the motherboard.
•  Disconnect the SAS/SATA cables and any NVMe cables (if present) from the disk backplane.
•  Remove the ESM Module from its dual lock strip on the chassis.
•  Remove the air divider by lifting it out of the chassis.  Lift ehe disconnected cables (SAS, NVMe, ESM) out of the divider.
•  Lift the air divider out of the system, leaving the cables (SAS, NVMe, ESM).
•  Carefully remove the SAS, NVMe, and ESM cables from the system noting exactly how they were placed between CPU0 heatsink and the power supply side wall.
•  Remove the data and power cables for the disk backplane.
•  Remove the power supply backplane data cable and the power supply backplane.
•  Remove any USB Flash drives attached to the internal USB Ports.
•  Remove the heatsinks and CPUs from the motherboard.
•  Remove the system battery.
•  Loosen the green captive screw that secures the motherbaord to the chassis. [Left fron corner behind FM3].
•  Remove the four bus bar screws securing the motherboard to the power supply backplane.
•  Position the cables off to the side, using the tab on the power supply cover.
•  Grasp the handle on the motherboard and slide it toward the front and then out of the chassis.
  • Note - If the locator indicator light pipe extension detaches during removal, ensure you retrieve it from the server.

5. Install the Motherboard and replace all removed components and cables in reverse order.

6. Return the server to operation by replacing the top cover, returning to the normal rack position and reconnecting the power cords to power supplies.

7. Power On the Server

8. Set the System Serial Number/Fruid if needed.

a. login to the ILOM as root and then enter the restricted shell to check the psnc values. Follow the example below to enter restricted shell and use the showpsnc command-

b. With a motherboard replacement the system should be able to automatically copy the psnc values from the primary and backup1 containers as long as they match.

c. As long as all of the psnc values match and are correct as in the above example this step is done. However if there was an issue during the replacement which caused the psnc values not to propagate automatically the system may need to be prompted to copy the data by either resetting the ILOM or scheduling a power cycle of the system by shutting down and removing the AC. If the SP reset or power cycle of the system does not synchronize the TLI data this will need to be fixed manually from service or escalation mode. These ILOM modes require a dynamic password and an Oracle Engineer for access. If Service mode is needed please contact the TSC and request assistance.

d.For Field Engineers: As long as all of the psnc values match and are correct as in the above example this step is done. However if there was an issue during the replacement which caused the psnc values not to propagate automatically then this will need to be fixed manually by using the copypsnc command from service or escalation mode. If you are unfamiliar with this process and require assistance please reference the steps for using copypsnc to fix the serial number detailed in the "How to update product serial number on systems which implement Top Level Identifier functionality (Doc ID 1280913.1)" and contact the TSC if needed.[This section is not visible to customers.]

OBTAIN CUSTOMER ACCEPTANCE

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

Boot up the server. Monitor and check the messages file under usual load by the server to check
CPU temperatures are normal. Use fmadm/fmdump to check for any faults and clear the ILOM/FMA logs if any old faults relating to the old motherboard unit assembly are found. Refer to the ILOM Supplement for the Oracle Server X5-4 for instructions on clearing faults.

Connect to the ILOM BUI and eventually clear any remaining faulty components (if, of course, they belong to the motherboard unit assembly).

NOTE: Motherboard replacement can lead to to a serial number of '00000000' which will break ASR if the motherboard is not reprogrammed after replacement.

In order to reprogram the serial number you will first need access into 'Service Mode' and this requires a long password which is obtained from our TSC backline. This 'Escalation' password is needed to reprogram the serial number of the system board.

An Escalation password (similar to service password) is valid for 48 hours, and is provided by our TSC backline. The following information is needed in order for the TSC backline to generate your temporary password granting access to Service Mode in order to reprogram the serial number.
You will initially need to provide the following information:

a. ILOM Version? (see "version" output)
b. Serial Number? (-> show /SYS [ or /CH ] product_serial_number )
c. When you will be onsite? (How soon do you need this escalation password?)

Please refer to document "How to update product serial number on systems which implement Top Level Identifier functionality" (Doc ID 1280913.1) for additional scope on reprogramming the serial number of the motherboard.
