Removing and Replacing Memory DIMMs
Your server has 12 memory sockets for installing DDR SDRAM memory DIMMs. The supported DIMM sizes
are 256 MB, 512 MB, 1 GB, 2 GB, or 4 GB. The server supports combinations from 1 GB up to 32 GB. See
Figure 4-23 for the DIMM slot locations on the system board.
WARNING Ensure that the server is powered-down and all power sources have been
disconnected from the server prior to removing or replacing server memory.
Voltages are present at various locations within the server whenever an AC power
source is connected. This voltage is present even when the main power switch is in
the off position.
Failure to observe this warning could result in personal injury or damage to
equipment.
CAUTION Observe all ESD safety precautions before attempting this procedure. Failure to follow ESD
safety precautions could result in damage to the server.
Supported DIMM Sizes
Supported DIMM sizes are 256 MB, 512 MB, 1 GB, 2 GB, and 4 GB. Memory in the server is installed in
quads. A quad of memory is a set of four matching DIMMs. Quad sizes may differ within the server as long as
all DIMMs within a quad match, unless you are installing 4 GB DIMMs. The only set up allowed with 4 GB
DIMMs is to install eight 4 GB DIMMs. The server supports combinations from 1 GB (using 256 MB DIMMs)
to 32 GB (using eight 4 GB DIMMs). See Figure 4-23 for the identification of quads.
