DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:
Netra T5220 Product Experience or Training

TASK COMPLEXITY: 2

TIME ESTIMATE: 90 Minutes

FIELD ENGINEER INSTRUCTIONS

PROBLEM OVERVIEW:  Defective system board

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :
A data backup is not a pre-requisite but is a wise precaution. System needs to be shutdown by customer

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Replacing the Motherboard Assembly

Caution – The SCC module contains system host ID, MAC addresses, and configuration variable settings for ILOM. If you are replacing a motherboard, you must move the SCC module from the old motherboard to the new one. You must also backup OpenBoot PROM variables for restoring after motherboard replacement since some variables such as the boot-device ARE NOT STORED ON THE SCC MODULE.


Removing the Motherboard Assembly

1. Back up OpenBoot PROM variables with one of the following procedures:
For ILOM 3.0 Web Interface – Back up per the Oracle Integrated Lights Out Manager (ILOM) 3.0 Web Interface Procedure Guide (820-0052). Use a passphrase to backup the OpenBoot PROM variables.
For ILOM 3.0 CLI – Back up per the Oracle Integrated Lights Out Manager (ILOM) 3.0 CLI Procedure Guide (821-1611). Use a passphrase to backup the OpenBoot PROM variables.
For ILOM 2.0 – The ILOM Back up/Restore feature is absent. Record output from the OpenBoot PROM printenv command or the Oracle Solaris eeprom command for use after motherboard replacement.

2. Prepare the server for motherboard assembly removal
See Section 4.1, “Powering Off and Powering On the Server” in the Service Manual

3. Remove the following components:
Air duct, System fan assembly, FB-DIMMs, Alarm board, SCC module (also known as IDPROM chip)

4. Disconnect the cables connected to the motherboard
a. Disconnect the cable connected to the PDB.
b. Disconnect the two cables connected to the media bay assembly.

5. Loosen or remove the screws that secure the motherboard assembly to the chassis

6. Loosen the two captive screws at the center of the motherboard assembly

7. Lift slighty and slide the motherboard assembly forward approximately one inch (25.4 mm)

8. Lift up on the right edge to approximately a 45 degree angle

9. Remove the motherboard assembly from the chassis

10. Set the motherboard assembly aside on an antistatic mat.


Installing the Motherboard Assembly

1. Remove the replacement motherboard assembly from its packaging and place it on an antistatic mat.

2. Lower the left edge of the motherboard assembly into the chassis, then the entire board, and while slightly elevated, slide the motherboard assembly to the back of the chassis

3. Align the motherboard assembly screw holes over the chassis standoffs

4. Tighten the two captive screws at the center of the motherboard assembly

5. Install the two power screws and four other screws that secure the motherboard assembly to the chassis

6. Reconnect the cables to the following connectors on the motherboard assembly

7. Install the following components: SCC module (also known as IDPROM chip), Alarm board, FB-DIMMs, Fan assembly, FB-DIMM/CPU

8. Bring the server back online

9. Restore OpenBoot PROM variables with one of the following procedures:
For ILOM 3.0 Web Interface – Restore OpenBoot PROM variables per the Oracle Integrated Lights Out Manager (ILOM) 3.0 Web Interface Procedure Guide (820-0052). Use the same passphrase used during the back up to restore the OpenBoot PROM variables.
For ILOM 3.0 CLI – Restore OpenBoot PROM variables per the Oracle Integrated Lights Out Manager (ILOM) 3.0 CLI Procedure Guide (821-1611). Use the same passphrase used during the back up to restore the OpenBoot PROM variables.
For ILOM 2.0 – Use the data collected during Step 1 of Section 4.10.1, “Removing the Motherboard Assembly” in the Service Manual to restore the OpenBoot PROM variables with the OpenBoot PROM setenv command.

10. Plug in power & power up system to return the server to operation line

NOTE: When replacing motherboard or service processor in LDOM environment, follow the steps and guidelines in Document 1019720.1 to prevent loss of LDOM configuration data and to recover LDOM configuration after replacement.
After replacing the RAID controller (system board), any existing HW RAID volumes (and member disks) may not be seen and need to be re-activated. If the Disk Volumes (including boot volume/disk) become inaccessible, consult: Unable to see a pre-existing RAID volume on Sun Fire[TM] T1000/T2000 Sun Sparc Enterprise T5120/T5140/T5220/T5240/T5440 (Doc ID 1009723.1)


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, then the component has been replaced successfully. No further action is required
3. Restart software applications per applicable administration guides to resume system operation.
