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.

Warning:

Ensure the replacement SP is of the correct type for the T8 system. The T8 SP can be identified by a black plastic cover, and the label: T8 Only Service Processor (SP). The previous versions of the Service Processor with the grey plastic cover, are NOT compatible with the T8 server and will not function. If the replacement Service Processor is not the correct type, STOP, and do not continue with the replacement procedure.

REMOVAL/REPLACEMENT INSTRUCTIONS:

PROBLEM OVERVIEW: SPARC T8-4 Service Processor Module (SPM) Replacement

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

Note:

A data backup is not a prerequisite but is a wise precaution.
If the system is still up and functioning, the Customer should perform an orderly and graceful shutdown of the applications and operating system.
NOTE: Restoring the SP configuration, after you replace the service processor, will be much simpler if the configuration has been saved using the Oracle ILOM backup utility. If the configuration has not been backed up, do so prior to the SP replacement if possible. Refer to the Oracle Integrated Lights Out Manager (ILOM) 4.0 Documentation for instructions on "Backing up and Restoring the Oracle ILOM configuration".
If you want to retain the same version of the system firmware with the new service processor, note the current version before you remove the service processor.
Then power off the server and remove the AC power cords from the system. For ALL scenarios where an AC power down or AC power cycle is required for a T8-x server, please always use the steps in doc 1571054.1 prior to physically removing AC power cables from the server.

WHAT ACTIONS ARE REQUIRED?:

Damage Alert:

Perform a visual inspection of the replacement part to make sure that there are no damaged components, connectors, bent pins, damaged packages during shipping, etc. If the part is damaged, don't install it into the system, order a new part. Handle with caution and package carefully the return part to avoid any damages during shipping.

Replace the Service Processor Module (SPM)
This component contains the backup tli, for more information look at:

- Top Level Identifier (TLI) locations on T3-x, T4-x, T5-x, T7-x, T8-x, S7-x Systems (Doc ID 2103218.1)

and once this component has been replaced, the backup tli will be automatically overwritten by the primary tli, this can be confirmed on the following way:

- -> set SESSION mode=restricted
       WARNING: The "Restricted Shell" account is provided solely to allow Services to perform diagnostic tasks.
       [(restricted_shell)]# showpsnc or [(restricted_shell)# showpsnc -v
       [(restricted_shell)]# exit

and for more information look at:

- How to use Restricted Shell on ILOM 3.0.10 and later platforms (Doc ID 1302296.1)

1. Prepare the server for service.

a. Power off the server and disconnect the power cords from the power supplies.
b. Attach an anti-static wrist strap.

2. Remove the main module motherboard from the server and remove it's cover.

3. Locate the service processor module (SPM) on the main module motherboard.

4. Grasp the service processor module (SPM) by the two grasp points, and lift up to disengage the SPM from the connectors on the main module motherboard.

5. Lift the service processor module (SPM) up and away from the main module motherboard and place it on an ESD mat.

6. Install the new service processor module (SPM) by lowering the side of the SPM with the Align Tab sticker down on the SPM tab on the main module motherboard.

7. Lower the other side of the service processor module (SPM) down and press down on the SPM to seat it into the connectors on the main module motherboard.

Caution - If the SPM does not slide into the socket with relative ease, do not force it. It may be that the SPM’s pins are not perfectly aligned with the socket. Excessive force could damage the pins, socket, or both.

8. Replace the cover on the main module motherboard and install it back into the server.

9. Return the Server to operation.

a. Remove any anti-static measures that were used.
b. Re-install the AC power cords and any data cables that were removed.

10. Prior to powering on the server, connect a terminal or a terminal emulator (PC or workstation) to the SP SER MGT port. If the SP detects that the new host firmware component is incompatible with SP firmware component, further action will be suspended and the following message will be delivered over the SER MGT port:

Unrecognized Chassis: This module is installed in an unknown or unsupported chassis. You must upgrade the firmware to a newer version that supports this chassis

If you see this message, go on to Step #12.

Note - Whenever you replace the SPM or the main module, update the firmware on the server so the portions of firmware in the two components remain consistent.

11. Download the system firmware.
a. Configure the SP’s network port to enable the firmware image to be downloaded. Refer to the Oracle ILOM documentation for network configuration instructions.
b. Download the system firmware. Follow the firmware download instructions in the Oracle ILOM documentation.

Note - You can load any supported system firmware version, including the firmware revision that had been installed prior to the replacement of the service processor.

c. If a backup file was created, use the Oracle ILOM restore utility to restore the configuration of the replacement service processor. Connect a terminal or a terminal emulator (PC or workstation) to the serial management port.

12. Set the ILOM time/date (-> set /SP/clock datetime=MMDDhhmmYYYY.ss)

13. Power on server. Verify that the Power/OK indicator led lights steady on.

14. Verify that the SP Status LED is illuminated green.

Note - The LED will flash green while the SPM initializes the Oracle ILOM firmware.

Important - Prior to booting your system the Solaris fallback image (miniroot) must be reloaded. This step can be performed when connected to the Service Processor using the Web Browser-Based Network Management Connection.
How to obtain the fallback image (miniroot):
http://docs.oracle.com/cd/E53394_01/html/E54742/gplct.html

Note -
For step "c" the entry for product field would be "SPARC T8-1.....or T8-2, T8-4"

For step "d" select from the drop down...."SPARC T8-1 Fallback Boot 11.3" <------------- or whatever the correct version needs to be

For step "e" hit search and select correct version of fallback version and download file to a location available to the browser that will be used for the loading
