CAUTION:
Make sure that all server power cords are disconnected from their power sources before performing
this procedure.
Important:
Before installing a memory module, make sure that you have selected the correct type of
memory module and understand the installation order, depending on whether you are implementing memory
mirroring, memory rank sparing, or independent memory mode. See
the
Memory Population Reference
for
specific information about installing memory modules and their required installation order, based on the
number of processors and memory modules in your system and the memory mode that you are
implementing.
See
http://www.lenovo.com/us/en/serverproven/
for a list of all the memory module types and capacities that
are supported for your server.
Notes:
• Do not mix RDIMMs and LR-DIMMs in the same server.
• Install higher capacity (ranked) DIMMs first, following the population sequence for the memory mode
being used.
• Installing or removing DIMMs changes the server configuration. When you restart the server, it displays a
message that indicates that the memory configuration has changed. There are multiple ways to view the
server configuration. See “Management options” on page 17 for a description of each management
method and how each method applies to various deployment situations.
