from the defective call manager card and fitted to the new call manager card.
To replace a call manager card, proceed as follows:

).
3. Unscrew the screw on the Call Manager card and remove the card by pulling the
fastening screw.
4. Replace the system modules (see

a new call manager card by replacing the Flash card.
