IBM BladeCenter HS12 Type 8014, Installation And User Manual

Page: 32 / 78

v
The optional DIMMs that are available for the blade server are 512 MB, 1 GB, 2
GB, and 4 GB. Depending on the memory configuration that is set in the
Configuration/Setup Utility program, the blade server can support a minimum
of 1 GB and a maximum of 24 GB of system memory on the system board.
v
When you install memory, you must install a pair of matched DIMMs. Some
blade server models come with one DIMM installed in DIMM slot 1. In this case,
you must order and install a second matched DIMM in DIMM slot 2. Install the
DIMMs in the order shown in the following table.

v All DIMMs in a pair or group must be the same size, speed, type, technology,
and physical design. You can use compatible DIMMs from different
manufacturers.
v
Install only ECC DDR2 667 DRAM with ECC DIMMs. For a current list of
supported DIMMs for the blade server, see http://www.ibm.com/servers/
eserver/serverproven/compat/us/.
v
Installing or removing DIMMs changes the configuration information of the
blade server. After you install or remove a DIMM, you must change and save
the new configuration information by using the Configuration/Setup Utility
program. When you restart the blade server, a message indicates that the
memory configuration has changed. Start the Configuration/Setup Utility
program and select
Save Settings (see “Configuration/Setup Utility menu” on
page 36 for more information) to save changes.
To install a DIMM, complete the following steps:
1.
Before you begin, read “Safety” on page v and “Installation guidelines” on
page 15.
2. Read the documentation that comes with the DIMMs.
3.
If the blade server is installed in a BladeCenter unit, remove it (see “Removing
the blade server from the BladeCenter unit” on page 16 for instructions).
