Change the IP Addresses of the TMG7800 Telecom Units
Note: For the TMG800 and TMG3200, skip this step.
Before you change the host's subnets, make sure that all of the Telecom Units of your TMG7800 system have had their IP addresses changed to the new subnet. For each Telecom unit of the TMG7800 system, do the following:
- Connect to Telecom Unit's shell (using Telnet, or serial port)
- Use "set_net" command
- Follow the instructions
- Reboot the unit
Resetting the Host Role of the Unit
Note: If your Unit was just shipped, it does not yet has it's "role" configured, and you can skip this step.
Changing the internal IP addresses of a TMG requires that the Unit's role (Standlone/Primary/Secondary) is reset. Once the role is reset, the Web Portal displays the steps to reconfigure the Unit's Role, and configure the internal Subnets.
Configure the Unit's Role
You can configure the host role of your unit, to the following choices:
Make sure to repeat this operation for the two units of your 1+1 system, or the two hosts of your TMG7800 system. In addition, make sure to start with the primary.
