DIMM Module Replacement
5-7
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, make sure
that the new DIMM module is firmly in place prior to re-installing
the controller module. If the DIMM module is not firmly in place,
the subsystem will not run and the whole procedure must be
repeated.
