You might need to install memory modules in the server. Use the
procedure in this section to perform this task.
If your system is managed by the Hardware Management Console
(HMC), use the HMC to complete the steps for installing the memory modules
in the server. For instructions, see Install a feature using the Hardware Management Console.
If you do not have an HMC, do the following to install the memory modules:
Disconnect the power source from the system by unplugging the system.
Note: This system may be equipped with a second power supply. Before
continuing with this procedure, ensure that the power source to the system
has been completely disconnected.
If necessary to access memory module positions on the system backplane,
disconnect the cables from the power supplies or service processor assembly
at the back of the system.
Determine the slots in which the memory modules will
be placed. See Figure 1 for
memory module slot locations on the system backplane.
Restrictions:
If your server has RIO/HSL ports P1-T3 and P1-T4 on the back of the system,
then memory modules must be installed in sets of four, or quads. Use the following
plugging order to install a quad of memory modules.
Exception: A 8950 processor might support a single pair of
memory modules on initial order, and must be upgraded to quads of modules
when adding memory.
The first quad of memory modules is placed into memory module slots C9,
C11, C14, and C16.
The second quad of memory modules is plugged into memory module slots
C10, C12, C13, and C15.
If your server does not have RIO/HSL ports P1-T3 and P1-T4 on the back
of the system, then memory modules are installed in pairs. Use the following
plugging order to install pairs of memory modules.
The first memory module pair is placed into memory module slots C9 and
C16.
The second memory module pair is placed into memory module slots C11 and
C14.
The third memory module pair is placed into memory module slots C10 and
C15.
The fourth memory module pair is placed into memory module slots C12 and
C13.

If necessary, remove the memory module from its antistatic package.
Ensure the connector is ready to receive the memory module by removing
the memory module filler, if one is present, by pushing the tabs A out
and then down. The lever action of the tabs forces the memory module filler
out of the connector.

Ensure that the connector locking tabs are pushed out to the unlocked
position before installing a new memory module.
Attention: Memory
modules are keyed to prevent a module from being installed incorrectly. Note
the locations of the key tabs within the memory module connector before attempting
to install the memory module.
Carefully grasp the memory module along two edges and align the
connector.
Insert the memory modules firmly into the connector.
Secure the memory module B with the locking
tabs A located at each end of the memory module connector,
as shown in the following figure.
