24 SUMMA
Networked Audio Production System
Getting Started
If the system is running actively on a
secondary controller card however, the
replacement can be hot-plugged into
the primary controller slot and it will
automatically take on the software and
user data running on the active secondary
card. Whilst this can avoid powering the
system down, it is not recommended
practise.
For compatibility checks and auto-
reprogramming across the system, the
primary controller needs to be active.
Whilst a system is running on a secondary
controller card, only a hot-plugged primary
controller will be checked/reprogrammed.
System User data is automatically copied
from the active controller to the alternate.
Before carrying out system wide software
upgrades, users should choose to back-
up the user data as a precaution via the
Software Updater application. Should a
system lose user data, e.g. a controller
card failure in a system that does not
have a secondary fitted, user data can be
restored by the Software Updater in order
to recover a system back to its previous
identity.
Router cards also contain system specific
user configuration. This is not currently
covered by the user data backup, and
custom configuration settings are not
automatically copied between the primary
and secondary router. In the event that a
router card needs to be replaced, users
should contact customer Support for
guidance on Router configuration.
If a controller card fails to reprogram, the
system will not attempt to retry. To retry,
upload the software package again (or a
different one) via the Software Updater
application.
