Defective memory boards can be replaced while the system is running
("hot plug"). The corresponding procedure is described in the operating
manual supplied with the server.
This manual describes how to replace memory boards when the system
is switched off.
The system board provides slots for four hot-plug memory boards, each of
which can accommodate up to four memory modules. Two memory modules
make up a so-called memory bank.
The slots are suitable for DDR II/400 MHz DIMM modules with 1 GB, 2 GB and
4 GB capacity. The board supports a maximum memory configuration of 64GB.

Memory modules must be installed in pairs of identical modules.
Figure 7: Fitting the memory banks
The memory capacity of the pairs installed on a memory board, however,
may differ: pair 1A/1B, for example, can consist of two 2 GB memory
modules and pair 2A/2B of two 1 GB memory modules.
