Replacing the Flash Card
The Flash card is fitted to the call manager card; in the event of a fault it is replaced
together with the call manager card.
Exception:
A defective call manager card can make it impossible to read out unstored configu-
ration data with AMS. In such cases the data can be saved using a new call manager
card by replacing the Flash card.
Note:
The Flash cards are expected to meet high demands in terms of data
security (read and write cycles). That is why only original Flash cards are
to be used.
