modules on the partner controllers should be of the same speed
and size.
The physical size:
The controller only supports DDR RAM
DIMM modules those are smaller than 30.5mm wide (1.2
inches).
Installation considerations:
When installing the DIMM module,
it is necessary to remove the controller from the chassis and
then remove the module from the controller. The controller board
is more susceptible to damage than the other components and
must be handled with extreme care.
•
Secure installation:
When replacing the DIMM module(s), make
sure that the new DIMM module(s) are firmly in place prior to re-
installing the controller module(s). If the DIMM module(s) are not
firmly in place, the subsystem will not be able to run and the
whole procedure must be repeated.

Upgrade/Replacement Procedure
To replace the DIMM module:
Step 1.
Remove the controller module from the subsystem
,
and place it on a clean, static-free surface. (See Section
5.2.2)
Step 2.
Remove the BBU module, if installed.
Carefully place

to the floor or place it near any heat source.
Step 3.
