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 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.
Power off the server and disconnect the power cables. See
