Caution:
z
Hold the DDR SDRAM only by its non-conductive edge, because it is prone to ESD
and could be damaged by incorrect operations.
z
You need to exercise some strength to pull the DDR SDRAM out of its bank but do
not overdo it.
z
Do not touch the components on the DDR SDRAM by hands.
z
The marks “DDR SDRAM1” and “DDR SDRAM2” in Figure 6-3 do not mean the
DDR SDRAMs are divided into basic and extended DDR SDRAMs; they are
identical.
6.3.3 Installing a DDR SDRAM
Follow these steps to install a DDR SDRAM.
Step 1: Locate the memory bank on the mainboard with reference to Figure 6-3.
Step 2: Hold the DDR SDRAM by its non-conductive top edge and place it in the
desired memory bank.
Step 3: Exercise adequate pressure on the DDR SDRAM to press it into the bank.
Press the clips at both sides of the bank inward until the locking pins at the end of the
clips are engaged with the semicircular recesses at the bottom of the DDR SDRAM.
Repeat these steps to install all the DDR SDRAMs.
6.4 Closing the Chassis Cover

Step 2: Hold the chassis cover and align the small tabs on the cover with the edges of
the bottom of the chassis.
Step 3: Push the chassis cover and ensure the tabs on the cover and the tabs on the
top of the front panel are engaged.
