Fig. 71 Software upload sequence
During a standard upload the PBX remains operational during the upload phase.
After a successful software upload, the PBX runs an automatic warm-start at the set
time and restarts with the newly loaded system software.
It is possible that there is insufficient storage space in Flash memory for the update
of the PBX software. In this case the wave files (Voice Mail, Courtesy and Music on
hold) can be stored on the PC and deleted from Flash memory. When the monitor-
ing phase is finished, the wave files can be reloaded to the PBX (see "Data of the
PBX File System", page 156).
If for whatever reasons the software upload is not possible or if a fault occurs dur-
ing the upload, the previous system software with the previous configuration data
remains activated.
If errors are detected in the system software during the time in which the newly
loaded system software is being monitored for fault-free operation, the previous
system software is reactivated.
Successful and failed software uploads are stored as event messages in the PBX
and output at the set signal destinations.
