Increase Server Memory with Additional DIMMs (16 Gbyte Configurations)

Before You Begin

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

The following 16 Gbyte configurations are supported:

¹Requires System Firmware 8.2.1.b or later.

To install 16 Gbyte DIMMs, do the following:

1. Consider your first steps:

   • Familiarize yourself with DIMM configuration rules.

     See DIMM Population Rules.

   • Prepare the system for service.

     See Preparing for Service.

2. Note the DIMM classification labels on the DIMMs currently installed in the server.

   See DIMM Rank Classification Labels.

   ---

   Note - The DIMM classification labels are visible with the DIMMs installed in the memory risers.

   ---

3. Note the DIMM classification labels provided in the upgrade kit.

   See DIMM Rank Classification Labels.

4. Remove all memory risers from the server. Arrange the memory risers in order on an ESD-protected work surface.

   See Remove a Memory Riser.

5. Remove all DIMM filler panels from all memory risers:
   1. At a DIMM slot that is to be upgraded, open the ejector tabs and remove the filler panel.
   2. Repeat Step a until all DIMM filler panels are removed.

   ---

   Note - Do not dispose of the filler panels. You may want to reuse them if any DIMMs are removed at another time.

   ---

6. Do one of the following:
   • If your upgrade DIMMs have the same rank classification as the installed DIMMs, install the upgrade DIMMs in all empty slots on all memory risers.

     See Install a DIMM.

   • If your upgrade DIMMs have a different rank classification from the installed DIMMs:
     1. Remove all DIMMs currently installed on the memory risers associated with CMP0.

        See Remove a DIMM.

     2. Install the DIMMs you removed in Step a into the empty slots on the memory risers associated with CMP1.

        See Install a DIMM.

     3. Install all of the DIMMs in the upgrade kit into all slots on the memory risers associated with CMP0.

        See Install a DIMM.

        1 Remove all DIMM fillers.

        2 Move existing DIMMs from risers associated with CMP0 to risers associated iwith CMP1.

        3 Install new DIMMs on risers associated with CMP0.

7. Insert the memory risers back into memory riser slots in the server.

   See Install a Memory Riser

   ---

   Note - Ensure that each riser is installed in the same slot from which it was removed. Installing the memory risers in the wrong slots might result in the server booting in a degraded state, with some or most of the memory disabled. See DIMM Configuration Error Messages.

   ---

8. Finish the installation procedure:

   • Return the server to operation.

     See Returning the Server to Operation

   • Verify DIMM functionality.
