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 off, and all power sources have been disconnected
from the server before removing or replacing server memory.
Voltages are present at various locations within the server when 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 can 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.
