About this task
This component can be installed as an optional device or as a CRU. The
installation procedure is the same for the optional device and the CRU.
After you install or remove a DIMM, you must change and save the new
configuration information by using the Setup utility. When you turn on the
compute node, a message indicates that the memory configuration has changed.
Start the Setup utility and select
Save Settings
(see “Using the Setup utility” on
page 26 for more information) to save changes.
If you are installing a DIMM as a result of a DIMM failure, you might have to
reenable the DIMM. To re-enable the DIMM, complete the following steps:
1.
Verify that the amount of installed memory is the expected amount of memory
through the operating system, by watching the monitor as the compute node
starts, by using the CMM
sol
command, or through IBM Flex System Manager
management software.

sol
command, see the "IBM Flex

For more information about IBM Flex System Manager management
software, see the "IBM Flex System Manager Software: Installation and
Service Guide" at http://ralfss21.raleigh.ibm.com:8099/help/topic/
com.ibm.acc.8731.doc/product_page.html.
2.
Run the Setup utility to reenable the DIMMs (see “Using the Setup utility” on
page 26 for more information).
The compute node has a total of 48 dual inline memory module (DIMM)
connectors. The compute node supports low-profile (LP) DDR3 DIMMs with
error-correcting code (ECC) in 4 GB, 8 GB, 16 GB and 32 GB capacities.
The following illustration shows the system-board components, including the
DIMM connectors.
