5. Remove the DIMM air baffle (see “Removing the DIMM air baffle” on page
50).
Attention: To avoid breaking the retaining clips or damaging the DIMM
connectors, open and close the clips gently.
6. Open the retaining clip on each end of the DIMM connector.
7. Touch the static-protective package that contains the DIMM to any unpainted
metal surface on the server. Then, remove the DIMM from the package.
8. Turn the DIMM so that the DIMM keys align correctly with the connector.
9. Insert the DIMM into the connector by aligning the edges of the DIMM with
the slots at the ends of the DIMM connector. Firmly press the DIMM straight
down into the connector by applying pressure on both ends of the DIMM
simultaneously. The retaining clips snap into the locked position when the
DIMM is firmly seated in the connector.
Important: If there is a gap between the DIMM and the retaining clips, the
DIMM has not been correctly inserted; open the retaining clips, remove the
DIMM, and then reinsert it.
10. Install the DIMM air baffle (see “Installing the DIMM air baffle” on page 51).
11. Install PCI riser-card assembly 2, if you removed it (see “Installing a PCI
riser-card assembly” on page 47).
Results
If you have other devices to install or remove, do so now. Otherwise, go to
“Completing the installation” on page 154. Go to the Setup utility and make sure
all the installed DIMMs are present and enabled.
Installing a hot-swap ac power supply
About this task
The following notes describe the type of ac power supply that the server supports
and other information that you must consider when you install a power supply:
v Make sure that the devices that you are installing are supported. For a list of
supported optional devices for the server, see http://www.ibm.com/systems/
info/x86servers/serverproven/compat/us/.
v Before you install an additional power supply or replace a power supply with
one of a different wattage, you may use the IBM Power Configurator utility to
determine current system power consumption. For more information and to
download the utility, go to http://www.ibm.com/systems/bladecenter/
resources/powerconfig.html.
v The server comes with one hot-swap 12-volt output power supply that connects
to power supply bay 1. The input voltage is 110 V ac or 220 V ac auto-sensing.
v You cannot mix 460-watt and 675-watt power supplies, high-efficiency and
non-high-efficiency power supplies, or ac and dc power supplies in the server.
v The following information applies when you install 460-watt power supplies in
the server:
– A warning message is generated if the total power consumption exceeds 400
watts and the server only has one operational 460-watt power supply. In this
case, the server can still operate under normal condition. Before you install
additional components in the server, you must install an additional power
supply
