Client Best Practice: Poll a NetGuardian Over Serial Using Another NetGuardian

Do you have sites that you must monitor outside of your LAN? Extending LAN to the site or running long serial lines can be very costly projects. Fortunately, there's a much better way that involves only short serial connections between sites.

Using the serial ports on your NetGuardian, you can actually monitor a second NetGuardian deployed outside of your LAN. This is done by polling the NetGuardian outside your LAN using a NetGuardian inside your LAN.

Your T/Mon polls the first NetGuardian through the LAN connection. The connection continues to the second NetGuardian via serial. In this way, alarms from an otherwise inaccessible NetGuardian can be forwarded to the first NetGuardian, and then to the T/Mon. This minimizes infrastructure required to achieve site visibility. When you LAN expands, you can easily "flip" your serial-polled sites over to LAN polling.

The NetGuardian's terminal server fucntionality allows you to monitor a number of devices outside of your LAN - including other NetGuardian RTUs.

DPS clients who already use this functionality find this to be an excellent way to monitor sites outside of the LAN's reach.
