Installing a memory module
Use this information to install a memory module
The following notes describe the types of dual inline memory modules (DIMMs) that the server supports and
other information that you must consider when you install DIMMs (see "System-board internal connectors"
on page 21).
If you are replacing a drive, make sure that:
• The server supports industry-standard, 1066, 1333 and 1600 MHz, PC3-12800 (single-rank or dual-rank)
double-data-rate 3 (DDR3), registered or unbuffered, synchronous dynamic random-access memory
Description
When this LED is lit, it indicates that the server is
connected to ac power.
A memory DIMM has failed or is incorrectly installed.
Microprocessor has failed, is missing, or has been
incorrectly installed.
System-board CPU VRD and/or power voltage regulators
have failed.
Indicates the status of the boot process of the IMM2.
When the server is connected to power this LED flashes
quickly to indicate that the IMM2 code is loading. When
the loading is complete, the LED stops flashing briefly
and then flashes slowly to indicate that the IMM2 if fully
operational and you can press the power-control button
