3. What happens if the PSA experiences an unplanned power interruption?
After a power outage the PSA will automatically recover and rebuild its settings as necessary. To reduce the
chance of data loss, the PSA can be connected to a UPS. (See the questions regarding
UPS below.)
Print jobs that were printing and print jobs that were spooled but not printing will automatically resume
when the PSA is powered up again. Print jobs that had not been spooled yet need to be resent.
Loss of power could initially cause corruption of the data on the PSA hard disk. However, the PSA is
designed to make internal data loss unlikely, since the corrupted data will be automatically corrected during
its next uninterrupted bootup.
It is always a good idea to have a
backup of the settings and files in case they need to be restored.
After a power outage or any other improper shutdown, the PSA may experience so many errors in its file
system that it rebuilds the disk from the default image. The printers, network configuration, and drivers will
be not be automatically restored. The configuration must be restored manually using the Restore
functionality with the last configuration manually
backed up.
