a.
If both sides of the memory carrier contain the same capacity of memory, install the
next quad in side 0.
b.
If side 0 contains more memory capacity, even though it may have less DIMMs than
side 1, install the next quad in side 1.
c.
If side 1 is full, install the remaining quads in side 0.
shows several examples of proper memory carrier loading order.
IMPORTANT:
The number in parenthesis indicates the order in which the quads are loaded.

Installing Memory
IMPORTANT:
You must pull the AC power plugs on the server every time you modify the DIMMs.
If you do not pull the AC power plugs, the system does not display the correct DIMM information.
To install memory, follow these steps:
1.
Unlatch the cover release lever on the top cover and remove the memory carrier assembly
cover. See
“Removing and Replacing the Memory Carrier Assembly Cover” (page 12)
NOTE:
You do not need to fully remove the top cover to service this component. However,
the top cover release lever must be open.
