FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: A Sun Fire X4800, Sun Server X2-8 (Sun Fire X4800 M2) Centerplane Assembly needs replacement

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

If the system is still up and functioning, customer should perform an orderly and graceful shutdown of applications and OS. Then power off the server and remove the AC power cords from the system. A data backup is not a prerequisite but is a wise precaution.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

How to Remove the Subassembly Module

1.Before replacing this component, backup the motherboard FRUID information.

How to Backup Motherboard FRUID Information

The server supports TLI and stores the TLI records in the motherboard (MB) FRUID container, called PRIMARY and in a file on the service processor (SP) filesystem, called BACKUP1. After adding or replacing a component in your server, you can initiate a backup of the latest TLI record information in the MB FRUID PRIMARY container to BACKUP1 on the SP filesystem using this procedure.

1.1 Enter Service mode.
How to access service mode and escalation mode on ILOM 3.x and later platforms (Doc ID 1019946.1)

1.2 To backup the PRIMARY container to the SP filesystem, enter the following command:

2. Prepare the server for service - shutdown OS and power off server.

3. Disconnect the AC power cables from the AC rear of the server.

4. Disengage the power supplies.
Partially remove the power supplies. This action ensures that the power supplies are disconnected from the midplane connectors.

5. Label and remove the CMODs and CPU filler modules.
CMODs and CPU filler modules must be returned to their original slots.

6. Disconnect the three hard drive backplane cables from the server midplane.

7. Label and disconnect the cables connected to the rear of the server.

8. Remove the four Fan modules.

9. Remove the fan controller boards.

10. Remove the Network Express modules or Network Express module Ffillers.
If you are not replacing the SAM, removal of this component is optional but recommended.

11. Remove the PCIe Express modules or PCIe Express module fillers.
If you are not replacing the SAM, removal of this component is optional but recommended.

12.Remove the SP module.

13.Use a long No. 2 screwdriver to loosen the five green captive screws that secure the SAM to the server chassis.
Two of the captive screws are accessible through the airflow vanes of Fan module bays FM 0 and FM 2. To access the screws lift open the top and bottom air flow vanes.

14.To remove the SAM, carefully slide it out of the chassis.


How to Install the Subassembly Module

1. From the back of the server, ensure that the hard drive backplane cables are correctly routed.

2. Position the SAM with the Fan module drive bay on the left.

3. Insert the SAM into rear of the server chassis.

4. Carefully slide the SAM into the chassis until it stops.
In this position the screws that secure the SAM to the interior chassis might not be touching their corresponding screw holes.

5. To ensure that the SAM mounting screws touch the interior screw holes on the chassis, firmly push the SAM inward until you can engage the screws.

6. To partially secure the SAM in the server, use a long No. 2 screwdriver to tighten the three right most green captive screws.
Two of the captive screws are accessible through the airflow vanes of Fan module bays FM 0 and FM 2. To access the screws lift open the top and bottom airflow vanes.

7. To fully secure the SAM in the server, carefully open the air vanes of the two left FMs and tighten the two green captive screws.

8. From the front of the server, connect the three hard drive backplane cables to the midplane.

9. At the rear of the server, install the fan controller boards.

10. Install the four Fan modules.

11. Install the Network Express modules or Network Express module fillers.

13. Install the SP module.
Reference doc: How to Install the SP Module
http://docs.oracle.com/cd/E19140-01/html/821-0282/gjfsk.html#scrolltoc

14. Connect any cables network cables to the rear of the server.

15. Restore and update the FRUID for the SAM serial number.
Reference doc: How to Restore Motherboard FRUID Information
http://docs.oracle.com/cd/E19140-01/html/821-0282/gksjp.html#scrolltoc


This procedure restores the FRUID backup.

To restore FRUID information, enter Service mode and type the following command:

Note: The MAC address and WWN from the backup is correct as these are an internal MAC and WWN, which is not used outside the server in any way.  So these do not need to be changed like with normal rack mount servers.  Just copy from the backup container to the primay is all that's needed here.


How to verify the Centerplane Assembly working properly.

1. Log into the ILOM.
2. Enter the following command to check status in normal status:

-> show /SYS

Example:

-> show /SYS/MIDPLANE

Example:

Check if any errors are displayed in the event log

Example

Check if any fault parts existed

Example

-> show faulty

Reference Doc ID: 1381773.1 to clear the fault.
