Note: The AT-TQ2403 Management Software acquires its date and time information
using the network time protocol (NTP). This data is reported in UTC format (also known
as Greenwich Mean Time). You need to convert the reported time to your local time.
For information on setting the network time protocol, see “Enabling the Network Time
Protocol Server”.
Enabling or Disabling Persistence
Persistence can be enabled or disabled from the Events tabbed page. The persistent log is saved in
NVRAM. Even after a reboot, all persistent logs are still reserved in NVRAM. Non-persistent logs are
only kept during the run-time period. If you reboot the access point, all non-persistent logs will be lost.
Enabling Persistence from the Events tabbed page ensures that all logs are written to NVRAM and even
after a reboot, these are recoverable.
Note: It should be remembered that enabling Persistence will result in a continuous write
operation. There is a risk that this will wear out the Flash element of the AP. You should
decide whether enabling Persistence is right for your needs, given the elevated risk of
wearing out the flash of the AP.

can be filtered using the Severity Configuration feature.
If you set the Severity level to 7, all messages with a severity level between 7 and 0 will appear in the
Event log. Alternatively, if you want to filter messages, you can set the Severity level to 4. In this instance,
