Caution
The electronic components on the printed circuit boards are extremely sensitive to
electrostatic discharge. Certain precautionary measures, therefore, have to be
taken when handling them. These measures are explained in the guidelines for
electrostatic sensitive devices (ESD Guidelines at the end of this manual).
Installing the SO DIMM Submodules
To insert the submodules, perform the following steps:
1. Open the unit first as described in section 4.1.
2. Insert the submodules into the sockets. Note the cutout (locking element) on
the connector side of the SO DIMM module.
3. Press the submodule down applying light pressure until it locks into place.
4. Close the device.
Caution
Danger of damage!
The submodules must be sit securely in the slots, otherwise they might fall out and
be damaged.

the distribution of base and extended memory is displayed on the screen.
