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
electrostatically sensitive devices in Appendix B.
Installing the SO DIMM Modules
To insert the modules, perform the following steps:
1. Open the unit first as described in section 4.1.
2. Insert the modules into the sockets. Note the cutout (locking element) on the
connector side of the SO DIMM module.
3. Press the module down applying light pressure until it locks into place.
4. Close the device.
Caution
!
Danger of damage!
The modules must be fitted firmly in the slots, otherwise they might fall out and be
damaged.
