Interface cards

The different card types, the number of slots and the maximum configuration are all de-
termined by the system capacity (see "3 Expansion Stages and System Capacity").
A number of rules have to be observed when fitting the cards (see "Component mount-
ing rules", page 111.
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.
