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. 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.
Important: In some memory configurations, the 3-3-3 beep code might sound
during POST, followed by a blank monitor screen. If this occurs and the Boot
Diagnostic Screen or QuickBoot Mode feature on the Start Options menu of
the Configuration/Setup Utility program is enabled (its default setting), you must
restart the server three times to force the basic input/output system (BIOS) to
reset the configuration to the default configuration (the memory connectors
enabled).
8. If you have other options to install, install them now. Otherwise, go to
“Completing the installation” on page 53.
Installing an additional microprocessor
The following notes describe the type of microprocessor that your server supports
and other information that you must consider when installing a microprocessor:
v
The server comes with one microprocessor installed. The following illustration
shows the two microprocessor sockets on the system board. The voltage
regulator modules (VRMs) for microprocessors 1 and 2 are on the system board.
Microprocessor 2 (CPU2) Microprocessor 2 error
LED (DLED14)
Microprocessor 1 (CPU1)
Microprocessor 1 error
LED (DLED13)
v
If one microprocessor is installed, it is installed in microprocessor socket 1
(CPU1) and supports both the startup and application processes.
v If you install a second microprocessor in the server, the server operates as a
symmetric multiprocessing (SMP) server, and operating-system application
programs can distribute the processing load between the microprocessors. This
