Memory Installation Notes

1. Populate the slots with black slots and black levers first: D0, D3, D6, D9, D12, D15, D18, D21. The slot population for the minimum DIMM configuration is D0/D6/D12/D18 per CMOD
2. Populate the slots with black slots and white levers second: D1, D4, D7, D10, D13, D16, D19, D22.
3. Populate the white slot, white lever slots last: D2, D5, D8, D11, D14, D17, D20, D23

How to Remove a DIMM

1. Prepare the server for service, shutdown OS and power off server.

2. Remove the 4x fan modules.

3. Remove the fan frame.

4. Remove the CMOD from the server.

5. Set the module on a flat antistatic surface with ample surrounding space and light.

6. Remove the CMOD cover.

7. Press the "DIMM FAULT REMIND BUTTON". This should turn on the slot LED for the faulty DIMM.

8. To unlock the DIMM, simultaneously rotate the two release levers outward fully away from the DIMM.
This action unlocks and ejects the DIMM from the DIMM slot.

9. Remove the DIMM from the CMOD.

How to Install a DIMM

1. Ensure that the DIMM slot locking levers are in the fully open position.

2. Align the DIMM within the slot.
The DIMM is notched to accommodate the key (protrusion) in the slot. The key ensures correct DIMM installation. The DIMM can only be correctly installed one way.

3. To install the DIMM, simultaneously press down on both ends of the DIMM to push it into the slot.
This action causes the DIMM locking levers to lift and lock into place on the DIMM.

4. Verify that the DIMM is properly installed and locked.
When properly locked in place, the DIMM cannot be removed.

5. Install the CMOD cover.

6. Install the CMOD into the server.

7. Install the fan fame.

8. Install the 4x fan modules.

9. After removing a CMOD the DPCCs associated with the CMOD removed/reinserted must also be reseated to ensure they have not become slightly unseated.

WHAT ACTIONS ARE REQUIRED TO RETURN THE SYSTEM TO AN OPERATIONAL STATE?:

Prepare server for operation, power on server and start OS.

How to verify the DIMM is working properly

Log in to the ILOM CLI.

Enter the following command to check status is normal status:

-> show /System/Memory/DIMMs/DIMM_x
note: the "x" represents the DIMM number of the DIMM replaced

Example:

-> show /System/Memory/DIMMs/DIMM_0

/System/Memory/DIMMs/DIMM_0
    Targets:

    Properties:
        health = OK
        health_details = -
        part_number = 001-0003-01,M393B2G70DB0-YK0
        serial_number = 00CE011412225F9C48
        location = P0/D0 (CPU 0 DIMM 0)
        manufacturer = Samsung
        memory_size = 16 GB

Use the fault management shell to clear the fault for a specific component:

For example:

faultmgmtsp> fmadm acquit /SYS/MB/P0/D0

or you can use the UUID

faultmgmtsp> fmadm acquit UUID

Check if any error output from event log

Example

-> show /SP/logs/event/list

Check if any faulted parts exist.

-> start /SP/faultmgmt/shell
Are you sure you want to start /SP/faultmgmt/shell (y/n)? y

Example

faultmgmtsp> fmadm faulty
No faults found

Check FMA and OS information to verify that no errors existed

Example

# fmadm faulty -a
STATE RESOURCE / UUID
-------- ----------------------------------------------------------------------

# prtdiag -v
System Configuration: Sun Server X4-8

Check /var/adm/messages file to verify that no errors existed

Example

bash-3.00# pwd
/var/adm

# grep -i warning messages
# grep -i error messages
# grep -i fail messages
