Mainboard

If the components on the mainboard are defective or permanently faulty, the entire
communication server with the metal chassis must be replaced.
To replace the communication server, proceed as follows:
Warning
Be sure to observe the "Safety regulations", page 84.
1. Back up the configuration data and audio data, if still possible.
2. Carry out preparations (see "Preparations", page 189).
3. Remove the housing cover.
4. Remove the interface cards (see "Interface cards", page 191), the system modules
(see "System modules", page 193) and the wiring adapter.
5. Change the EIM card of the defective mainboard to the new mainboard (see "Re-
placing the EIM card", page 194).
6. Dismantle all the connected cables in such a way that the new communication
server can be identically reconnected.
Note: The mainboard is not dismantled but replaced complete with metal housing.
7. The new communication server can now be reassembled, fitted and installed in the
reverse sequence.
8. Carry out a first start of the system (see "First start of the communication server",
page 178) and upload the configuration data from a backup file back on to the com-
munication server.
