  26. Exit to the Master Menu.
  27. Select "Initialize"
  28. Select "Monitor"

Your NetGuardian should now be correctly set up within T/Mon.

To verify that your NetGuardian is being correctly polled by T/Mon, you may wish to perform the check described below:

  • From the Alarm Summary screen in Monitor Mode, press Shift+F6 to reach the Site Statistics screen
  • Adjust view to NetGuardian polling leg. You should see the number of polls rising as the new NetGuardian is polled by T/Mon.

If the polls are failing, try to ping the NetGuardian's IP address.
If the NetGuardian responds to pings but is not being polled correctly, check its configuration settings. The most common errors are an incorrect TCP port or Unit ID.

The following image is a reference to assist you in correctly filling in these fields.

Matching UnitID, SiteID, DCP Port fields
The UnitID, SiteID, and DCP Port fields should match. The IP address circled in pink must also match the IP address configured on the 'Ports' tab of NGEdit or the NetGuardian Web Interface.

If you continue to have issues setting up a NetGuardian within T/Mon, please contact DPS Telecom Tech Support.
