How to replace a 220R and 420R Dimm Module

Solution

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:(IS A SITE ENGINEER AVAILABLE?)

420R/220R product knowledge/training to be qualified as Oracle service personel.

TIME ESTIMATE: 50 minutes

TASK COMPLEXITY: 1

FIELD ENGINEER INSTRUCTIONS

PROBLEM OVERVIEW:

Memory/DIMM Failure

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.

The customer should conduct an orderly software system shutdown.

Then power down the system and disconnect the Power Cord, remove the system cover, avoid Electrostatic Discharge, and then Remove the Memory Riser Assembly.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

220R Memory Notes:

Memory modules for this system are dual inline memory modules (DIMMs). Each DIMM bank must contain four DIMMs of equal density (for example, four 64-Mbyte DIMMs) to function properly. Supported DIMM configuration options are 32, 64, and 128 megabytes.

The following memory configuration rules apply to your system:

 - At least one memory bank (all four bank slots) must be filled for the system to boot.

 - DIMMs must be added four at a time within the same bank.

 - DIMM capacities can differ from one bank to the next—for example, four 64-Mbyte DIMMs installed in bank 0 and four 128-Mbyte DIMMs installed in bank 2 is permissible.

Please refer to the Sun Enterprise 220R Server Service Manual for Dimm Locations.

420R Memory Notes:

Memory modules for this system are dual inline memory modules (DIMMs). Each DIMM bank must contain four DIMMs of equal density (for example, four 64-Mbyte DIMMs) to function properly. Supported DIMM configuration options are 32, 64 and 256 Mbytes.

The following memory configuration rules apply to your system:

 - At least one memory bank (all four bank slots) must be filled for the system to boot.

 - DIMMs must be added four at a time within the same bank.

 - In the Sun Enterprise 420R server, each memory bank comprises two slots on the main logic board and two slots on the memory riser card. As you add memory, fully populate a bank by inserting DIMMs into the two slots corresponding to that    bank on both the main logic board and on the memory riser card.

 - DIMM capacities can differ from one bank to the next—for example, four 64-Mbyte DIMMs installed in bank 0 and four 256-Mbyte DIMMs installed in bank 2 is permissible.

Please refer to the Sun Enterprise 420R Server Service Manual for Dimm Location and Memory Interleaving details.

Caution – DIMMs are made of electronic components that are extremely sensitive to static electricity. Static electricity from your clothes or work environment can destroy the DIMM. Always wear a grounding strap when you handle the modules.

Caution – Do not remove any DIMM from its antistatic packaging until you are ready to install it. Handle the modules only by their edges. Do not touch the components or any metal parts. Always wear a grounding strap when you handle the modules.

How to Remove a Memory Module:

1. Locate the memory module(s) to be removed.

420R Only: If the module is located on the memory riser assembly, remember that you must first remove the memory riser assembly before removing the memory modules.

Note – If the module to be removed is on a socket on the main logic board, use the same procedure explained in Steps 2 through 4.

2. Push the ejection lever away from the memory module and eject it from the socket.

420R Only: Be sure that the back of the memory riser assembly is supported when you remove the module.

3. Grasp the top corners of the memory module and pull it out of its socket.

4. Place the module on an antistatic mat.

5. Repeat Steps 2 through 4 for each memory module being removed.

How to Install a Memory Module:

Note - Please ensure you follow the memory configuration rules for the server on which you are working (see above for details - 'What Actions does the Engineer need to take'.

1. Remove the new memory module from its antistatic packaging.

2. Locate the socket into which you will install the memory module.

420R Only: Caution – If you are installing a DIMM in the memory riser assembly, be sure to place the memory riser on an antistatic mat with the sockets facing up. You must support the assembly while inserting the DIMM to avoid flexing the card.

3. Position the module so that the small notch on the bottom corner of the module is at the same end as the socket's ejection lever.

4. Align the module with its socket until it contacts the socket evenly along the socket's length.

5. Press firmly down on both corners of the module until the bottom edge is firmly seated in the socket.

 - You will hear a clicking sound when the module is fully seated.

6. Repeat Steps 3 through 5 for each module you want to install.

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:

When you are ready to restart the system, be sure to run OpenBoot Diagnostics tests to verify that the system functions correctly with the new parts you have just installed.
Restart software applications per applicable administration guides to resume system operation.
