6. 3. 3 Interface cards
The different card types, the number of slots and the maximum configuration are
all determined by the system capacity (see "3 Expansion Stages and System Capac-
ity").
A number of rules have to be observed when fitting the cards (see "Component
mounting rules", page 113.
All configuration data is centrally stored in non-volatile Flash memory. This means
that configuration data is preserved whenever a defective interface card has to be
replaced by a new one.
