DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:
Netra T4-2 Server product training.

TIME ESTIMATE: 90 minutes

TASK COMPLEXITY: 1

FIELD ENGINEER INSTRUCTIONS

PROBLEM OVERVIEW: Netra T4-2 Motherboard replacement.

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

Flash memory on the motherboard stores this information:
■ OBP NVRAM configuration variables
■ POST configuration variables
■ SC configuration variables (IO reconfig, power mgmt, boot mode)
■ ASR database
■ Saved Oracle VM Server for SPARC logical domains configuration
■ Console log
■ System error report log
■ Time of day data (tod-offset)
If you are removing the motherboard for replacement, this information will be lost.  Record the information as necessary before powering off the server. Refer to the Oracle Solaris documentation for more information.

NOTE: The LDOM configuration data (if any exists) needs to be saved before motherboard replacement to avoid loss of LDOM configuration, refer to doc 1019720.1 for details.

1. Prepare for servicing:
a. Attach an antistatic wrist strap.
b. Power off the server and unplug power cords from the power supplies.
c. Extend the server to maintenance position.
d. Remove the top cover.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Removing the MotherBoard.
1. Remove the front fan modules.

2. Remove the PCIe cards.

3. Remove the SP.

4. Remove the NVRAM.

5. Remove the memory risers.

6. Remove the subchassis.

7. Disconnect all cables from the motherboard.

8. Loosen the four captive screws of the bus bar blocks.

9. Remove the two bus bar blocks.

10. Loosen the 4 captive screws at the rear panel of the chassis.

11. Loosen the four captive screws at the front edge of the motherboard.

12. Slide the motherboard forward and lift it slightly.

13. Raise the right side of the motherboard up and lift the motherboard out of the chassis, toward the right.

14. Remove the service processor from the motherboard so you can reinstall it on the new motherboard


Installing the Motherboard

1. Install the removed service processor onto the new system board

2. Collect the cables to the left of the chassis.

3. Align the motherboard to the location where it installs into the chassis.  The components point up, and the connectors are at the rear of the chassis.

4. Lower the left side of the motherboard, so that the edge rests in the left corner.

5. Lower the motherboard completely into the chassis, and slide it back toward the rear of the chassis.

6. Secure the 4 captive screws at the rear panel of the chassis.

7. Secure the four captive screws at the front edge of the motherboard.

8. Install the two bus bar blocks.

9. Tighten the four captive screws of the bus bar blocks

10. Connect all cables to the motherboard.

11. Install the subchassis.

12. Install the memory risers.

13. Install the NVRAM.

14. Install the SP.

15. Install the PCIe cards.

16. Install the front fan modules.

17. Complete reinstallation - attach front cover, slide into rack, & power on the ILOM.

18. Connect a terminal or a terminal emulator (PC or workstation) to the SP SER MGT port & connect power to the system without powering on the host.

NOTE: Re-activate any RAID volumes that existed prior to replacing the motherboard. Only perform this task if your system had RAID volumes prior to replacing the motherboard. For details refer to doc 1387771.1.

NOTE: If you do not see the message below, then skip Step 19.

  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.

19. If a FW mismatch, Download the system firmware.

If needed, configure the SP network port to enable the firmware image to be downloaded.

Refer to the Oracle ILOM documentation for network configuration instructions.
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 motherboard.

CAUTION: In case the FW upgrade via ILOM BUI fails, please use the CLI method (see example in doc 2019500.1). You may need a source of TFTP in order to upgrade firmware via CLI commands, for details refer to: Solaris[TM] Operating System: How to set-up a TFTP server. (Doc ID 1004474.1). See also doc 2076315.1

ALERT: In some cases when updating the SysFW via CLI (and during CLI execution), it may fail with the following error:

If that happens, refer to doc 1517032.1 for the workaround steps (confirmed by FSEs to be a successful workaround in resolving the issue). 

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

21. Power on the host.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE FE/CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:
Boot system and monitor boot sequence for errors. Test functionality of system:
1. Run the Solaris "fmadm faulty" and SP/ILOM "show faulty" command (if only ALOM is supported run "showfaults -v" command) to verify that the fault has been cleared.
2. Perform one of the following tasks based on your verification results:
   * If the previous steps did not clear the fault, refer to doc 1004229.1 for information about the tools and methods you can use to diagnose and clear
     component faults.
   * If the previous steps indicate that no faults have been detected, the component has been replaced successfully. No further action is required
3. Restart software applications per applicable administration guides to resume system operation.
