PROBLEM OVERVIEW: Memory DIMM replacement

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :
The customer should conduct an orderly software system shutdown. A data backup is not a pre-requisite but is a wise precaution.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Note - This is a cold service procedure that can be performed by customers.

Caution - Do not leave DIMM slots empty. You must install filler panels in all empty DIMM slots.

Remove a DIMM

1. Perform the preliminary steps required for cold service procedures.
2. Extend the server to the maintenance position.
3. Attach an antistatic wrist strap.
4. Remove the top cover.
5. For SPARC servers, swing the air duct up and forward to the fully open position. For Netra servers, the DVD tray may have to be removed.
6. Press the Remind button on the motherboard to identify the DIMMs that need to be replaced.
7. Push down on the ejector tabs on each side of the DIMM until the DIMM is released.

Caution - DIMMs and heat sinks on the motherboard may be hot.

8. Grasp the top corners of the faulty DIMM and lift it out of its slot.
9. Place the DIMM on an antistatic mat.
10. Repeat Step 7 through Step 9 for any other DIMMs you intend to remove.
11. If you do not plan to install replacement DIMMs at this time, install filler panels in the empty slots.

Install a DIMM

1. Perform the preliminary steps required for cold service procedures.
2. Extend the server to the maintenance position.
3. Attach an antistatic wrist strap.
4. Remove the top cover.
5. Swing the air duct up and forward to the fully open position.
6. Unpack the replacement DIMMs and place them on an antistatic mat.
7. Ensure that the ejector tabs on the connector that will receive the DIMM are in the open position.
8. Align the DIMM notch with the key in the connector.

Caution - Ensure that the orientation is correct. The DIMM might be damaged if the orientation is reversed.

9. Push the DIMM into the connector until the ejector tabs lock the DIMM in place.
   - If the DIMM does not easily seat into the connector, check the DIMM’s orientation.
10. Repeat Step 7 through Step 9 until all new DIMMs are installed.
11. For Sparc servers return the air duct to the closed position. For Netra servers, the DVD tray should be reinstalled if removed.
12. Install the top cover.
13. Slide the server into the rack.
14. Connect the power cords.

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.
