2. Lift the cover-release latch. The cover slides to the rear approximately 13 mm (0.5 in.). Top cover Cover release latch Bezel xSeries 365 3. Lift the cover off the server. 4. Press on the bezel retention tabs and pull the top of the bezel slightly away from the server. 5. Pull the bezel up to release the two tabs at the bottom edge of the bezel. Attention: For proper cooling and airflow, replace the top cover before turning on the server. Operating the server for more than 2 minutes with the top cover removed might damage server components. Installing memory modules The following notes describe the types of dual inline memory modules (DIMMs) that your server supports and other information that you must consider when installing DIMMs: v Your server supports 2.5 V, 184-pin, error correcting code (ECC), double-data rate (DDR) SDRAM, PC2100 registered DIMMs with Chipkill memory protection. v DIMMs can be removed and replaced through the access doors on the top of the memory cassette. v You can increase the amount of memory in the server by replacing the DIMMs with higher-capacity DIMMs or installing additional pairs of DIMMs in open sockets. The server supports 512 MB, 1 GB, and 2 GB DIMMs. See the ServerProven list at http://www.ibm.com/pc/compat/ for an updated list of memory modules supported by the server. v For a server with an 8-DIMM-connector memory cassette, you can increase the memory capabilities of your server by upgrading to the 16-connector memory cassette. The 16-connector memory cassette supports memory mirroring and Memory ProteXion. See the ServerProven list at http://www.ibm.com/pc/compat/ for a list of memory cassettes supported by the server. v Your server uses interleaved DIMMs, which require that you install the DIMMs in specific configurations: - In the 8-DIMM-connector memory cassette, install DIMMs in pairs. Each pair must be of the same type, capacity, and speed. The DIMM connectors are arranged in two groups of four rows each; the server comes with one pair of DIMMs installed in DIMM connectors 1 and 5 in the memory cassette. - In the 16-DIMM-connector memory cassette, the DIMM connectors are arranged in two groups of eight rows each. In non-mirrored mode, install Chapter 2. Installing options 9

Installing
memory
modules
The
following
notes
describe
the
types
of
dual
inline
memory
modules
(DIMMs)
that
your
server
supports
and
other
information
that
you
must
consider
when
installing
DIMMs:
v
Your
server
supports
2.5
V,
184-pin,
error
correcting
code
(ECC),
double-data
rate
(DDR)
SDRAM,
PC2100
registered
DIMMs
with

memory
protection.
v
DIMMs
can
be
removed
and
replaced
through
the
access
doors
on
the
top

the
memory
cassette.
v
You
can
increase
the
amount
of
memory
in
the
server
by
replacing

DIMMs
or
installing
additional
pairs
of
DIMMs

an
8-DIMM-connector
memory
cassette,
you
can
increase
