and lower is installed.
„
Open the Registry Editor, navigate to the

Auto Recovery
Symptom Solution
The time on the
module has moved to a
past time. This causes
existing archives to
have future
timestamps or
overlapping archives:
„
First, check the module’s time source to ensure that it is
correct. See information in “Time Management Issues” to
resolve time source issues.
„
If the issue is not a time source issue, restore the module to
its proper state by rebooting it. The module will start in
safe mode.
„
Click Safe Mode that initially displays when the module is
rebooted. (Safe Mode indicates that your system is in safe
mode.)
„
Download archives to retain the archive data for your
records.
„
Next, delete the archives with future timestamps or over-
lapping archives. See “Repairing Archives” for more
information.
