Reconnecting a Gateway or ATA to the System
If there are no more than five Gateways in the system (four PSTN Gateways and one T1
Gateway), and a Gateway or ATA screen displays Synch Failed or Synchronizing for
more than a few minutes, you may need to remove the Gateway or ATA from the system
and reconnect it. This problem may have been caused by the Gateway or ATA having
been part of a different network or by a network disruption, which may have been caused
by an AC power failure.
To reconnect a Gateway or ATA to the system:
1. Ensure that the Gateway or ATA is connected to the same LAN as other system
Gateways, Desksets, and the PC you will use to access the WebUI. Confirm that the
first three octets of the IP address match other devices in the system.
2. Back up the system if you are reconnecting a Gateway and this is the only Gateway.
a. Log on to the WebUI as administrator using the Gateway or ATA IP Address
shown on the Gateway or ATA display.
b. Click Device Management, then Back up/Restore, then System Settings in
the WebUI navigation menu at left.
c. Click Back up System Settings and save the file to a specified location on your
computer. You will need to locate and retrieve this file later, so make sure you
remember where you saved it. The file name will be in the format:
backup_system_[year]-[month]-[day]_[time].cfg.
If you back up the system less than one minute after creating another backup,
you may overwrite the earlier file.
The system backup also saves ATA setup information.
3. Disconnect the Gateway or ATA from the network by unplugging the Ethernet cable
from the LAN port located on the front of the Gateway or ATA.
4. Complete a factory reset to restore factory values. Insert a pen or the end of a paper
clip into the RESET button (located on the front of the Gateway and ATA) and hold
it for more than five seconds until the LCD displays Restoring to factory defaults.
5. Reconnect the Gateway or ATA to the network and ensure that it synchronizes with
the other devices.
6. If you are reconnecting the only system Gateway, restore your settings.
a. Log on to the WebUI as administrator at the PC where you stored the backup file.
b. Click Device Management, then Back up/Restore, then System Settings in
the navigation menu at left.
c. Under Restore System Settings, click and select the correct backup
file.
d. Click Restore System Settings.
If you are reconnecting a Gateway or ATA, and there are other Gateways
that are synchronized, this step is not necessary.
