6. 3. 6 Call manager card CPU1
If the components on the call manager card are defective or permanently faulty,
the entire call manager card must be replaced. As a spare part the call manager
card does not contain any RAM module, Flash card or EID card. They can be taken
from the defective call manager card and fitted to the new call manager card.
To replace a call manager card, proceed as follows:
Warning
Be sure to observe the "Safety regulations", page 95.
1. Backup the configuration data using AMS if still possible.
2. Carry out the preliminary steps if still possible (see "Preparations", page 221).
Note: If the call manager cannot be shut down in the normal way, its shutdown
has to be forced (see "Display and control panel of the call manager", page 240).
3. Unscrew the screw on the Call Manager card and remove the card by pulling the
fastening screw.
4. Replace the system modules (see "System modules", page 226), the system cards
(see "System cards", page 230) on the new call manager card.
5. Dismantle all the connected cables in such a way that the new communication
server can be identically reconnected.
Note: The CPU card is not dismantled but replaced complete with metal hous-
ing.
6. The new communication server can now be reassembled, fitted and installed in
the reverse sequence.
7. Restart the call manager by pressing the On/Off button on the call manager
card.
8. Carry out a first start of the system (see "First start of the communication server",
page 207) and upload the configuration data back on to the communication
server using AMS.
Tip:
A defective call manager card can make it impossible to read out
unstored configuration data with AMS. In such cases the data can be
saved using a new call manager card by replacing the Flash card.
