WHAT SKILLS DOES ENGINEER NEED:
Sun X86 Servers

Task Complexity: 3

TIME ESTIMATE: 180 minutes



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

- Write down serial number of original board.
- Be aware the MB FRU ships with non-netra BIOS and must be flashed with the netra specific BIOS as mentioned below in step 15.
- If needed, the netra specific BIOS FWs are here: http://www.oracle.com/technetwork/systems/patches/firmware/release-history-jsp-138416.html#NX4200
- Confirm the customer has a copy of original BIOS and ILOM configuration parameters.
- Power-off the server.
- Disconnect cables from the server.
- Remove the server from the rack.
- Perform antistatic measures.

WHAT ACTION DOES ENGINEER NEED TO TAKE:

Step I: Remove Faulty Motherboard

1. Remove the top cover.
2. Remove the PCI Tray and PCI-E Ribbon cables.
- Disconnect the PCI tray cable at location J2 and loosen the thumbscrew adjacent to it.
  Note: The thumbscrew is captive and cannot be fully removed from the PCI tray.
- Slide the PCI tray back about 1 inch (25 mm) and lift up on the back edge.
3. Remove the PCI-E cable hold-down bracket.
- Loosen the three captive screws that hold the PCI-E cable hold-down bracket in position, and lift the U-plate up and off of the motherboard.
4. Remove the PCI-E cables.
5. Remove the DIMM/CPU duct.
- Raise the DIMM/CPU duct into the vertical position.
- Unhook the duct from the pins of the chassis.
- Lift the duct out of the chassis, and set it aside on an antistatic mat.
6. Remove the system fan assembly.
- Undo the thumbscrew at location J2 and slide the PCI tray back to the fully open position.
- Reach down behind the flex circuit.
- Disconnect the fan assembly cable at connector J3 on the power board by depressing the connector retention latch while pulling the connector housing straight up.
- Remove the fan assembly cable from the cable guides.
- Insert your forefinger and thumb into the holes at the top of the fan assembly, squeeze your fingers together, and lift the fan assembly from the chassis.
7. Remove DIMM(s).
- Identify the DIMM to remove and press the ejector levers open, releasing the DIMM.
Note – To push the DIMM SW2 button, the PCI Tray must be removed and the button must be pushed through the hole in the PCI-E cable hold-down bracket.
8. Remove the Alarm Board.
- Disconnect all three cables from the alarm board at their connectors.
- Push down on the green tab, pivot the alarm board inward, and lift the alarm board out of the chassis.
9. Remove the GRASP board.
- Squeeze the plastic standoff that protrudes through the GRASP board to press the standoff’s locking tabs. If you have difficulty pressing the locking tabs with your fingers, you can use a pair of long-nosed pliers.
- Raise the corner of the GRASP board until it is clear of the locking tab.
- Pivot the front edge of the GRASP board upward to disengage it from the rear plastic bracket and to disengage its connector from the motherboard.
10. Disconnect the cables from the following connectors on the motherboard assembly:
- Flex Circuit (J7)
- Front I/O (J23)
11. Use an 8mm nut-driver to remove the two bus-bar nuts and six other screws that secure the motherboard assembly to the chassis.
12. Use the lifting handle to raise the forward edge of the board until it has cleared the bus-bar studs.

Caution – When lifting the board, use caution to avoid damaging the light pipes and connectors on the rear edge of the motherboard.

13. Slide the board toward the front of the chassis until the connectors and light pipes are clear of the chassis back panel gasketing. Then raise the motherboard and remove it from the chassis.
14. Set the motherboard assembly aside on an antistatic mat.
15. Installing the motherboard assembly.
Note – After you replace the motherboard FRU, you must use the servicetool command to update FRU information about the motherboard.

Step II: Install New Motherboard

1. Remove the replacement motherboard assembly from its packaging and place the assembly 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, carefully seating the rear I/O connectors into the rear gasketing.
3. Align the motherboard assembly screw holes over the chassis standoffs.
4. Install the two bus bar screws and five other screws.
5. Reconnect the cables to the following connectors on the motherboard assembly:
- Flex Circuit (J7)
- Front I/O (J23)
6. Install the GRASP Board.
To install the GRASP board, reverse the steps you used to remove the GRASP board.
Push firmly on the center of the board to avoid bowing and ensure full mating of the motherboard connector.
7. Replace the Alarm Board.
- Align the tabs of the alarm board with the slots in the chassis wall.
- Swing the alarm board up to the chassis wall until it clicks into place.
- Reconnect all three cables to the alarm board at their connectors.
- Route the cables into the cable guides.
8. Installing DIMM(s).
- Ensure that the DIMM slot ejectors at each end of the memory socket are fully open (rotated outward) to accept the new DIMM.
- Align the notch in the bottom edge of the DIMM with the key in the DIMM socket.
- Press down evenly on both top corners of the DIMM until the ejectors snap over the cutouts in the left and right edges of the DIMM.
Note: Install DIMMs in pairs into alternate slots.
9. Install the System Fan Assembly.
- Insert your forefinger and thumb into the holes at the top of the fan assembly, squeeze your fingers together, and lower the fan assembly into the chassis.
- Reconnect the system fan assembly cable to connector J3 on the power board.
Note: The connector is not easy to see because it is positioned under the flex circuit.
- Route the fan assembly cable back into the cable guides.
10. Install the DIMM/CPU Duct.
- Position the duct vertically over the pins of the chassis and hook the duct to the pins of the chassis.
- Lower the duct down to the horizontal position.
11. Reconnect cables for PCI-E.
12. Install cable hold-down bracket.
13. Install PCI Tray.
14. Perform the following tasks to bring the server back online:
- Install the Top Cover.
- Reinstall the Server Chassis in the Rack.
- Reconnect Cables to the Server.
- Power-on the Server.
15. Once installed:
- Flash the netra specific BIOS.  One method to check the BIOS revision is via CLI to the service processor.
- Netra specific BIOS will either have 0ABLGnnn or 0ABRMnnn for the version, whereas the non-netra BIOS versions will identified as 0ABJXnnn.
  For example:
  -> show /SYS/MB/BIOS fru_version
       fru_version = 0ABRM002

- After the netra specific BIOS has been installed, the new motherboard needs to have chassis/system dynamic serial number/part number information programmed using the servicetool update procedure as shown below in Step III.

Step III: Servicetool FRU Update Procedure

Caution – The sunservice account is for the use of Sun service representatives only. Do not use the sunservice account unless you are instructed to do so in a procedure developed by Sun Microsystems.

1. Use SSH to log into the sunservice account. The default password is changeme.
# ssh <SP IP address> -l sunservice
# <SP IP Address>'s password: changeme
2. At the prompt, enter the servicetool command with options. The options are defined in the table below.
# servicetool --fru_update=mainboard <Other Options>=<value>

3. Watch the output from the command and respond to the confirmation prompts to continue the update and to reboot the server:
Servicetool is going to update the mainboard FRU with product and chassis information collected from the removed mainboard.
The following preconditions must be true for this to work:
    * The new mainboard must be installed.
    * The service processor must not have been replaced with
the motherboard.
    * The service processor firmware must not have been upgraded
      prior to the motherboard replacement; do firmware upgrades
      after component swaps!
Do you want to continue (y|n)? y
Mainboard FRU configuration has been updated.

WHAT ACTION DOES CUSTOMER NEED TO TAKE TO RETURN SYSTEM TO AN OPERATIONAL STATE:
1. Boot up server.
2. Monitor and check messages file (if Solaris or Linux) under usual load by server to check for normal CPU temperatures and operation.
3. Use fmadm/fmdump to clear previous faults affecting old system board.
4. Connect to BUI and eventually clear any remaining faulty component, if applicable to system board assembly, clear SEL log and reset SP.
