  • Page 53: Module Types

    78. Voice modules You can hot-swap voice modules. This means you can add a voice module to the Avaya G350 Media Gateway while the system is running, without any disruption to your network. Configuration of the G350 is not necessary when you add a voice module. Configuration is only necessary when you add telephones, fax machines, and trunks to the new module.

  • Page 54: Data Modules

    You can hot-insert data modules. This means you can add a data module to the Avaya G350 Media Gateway while the system is running, but the G350 resets when you add the module. However, hot insertion is not recommended in most cases. Because hot insertion resets the G350, any translation and other data that is in the running configuration but has not been saved to the startup configuration will be lost.
  • Page 55 To insert a media module: Remove the blank plate from the empty slot. Position the media module squarely before the selected slot on the front of the G350 chassis and engage both sides of the module in the interior guides.

  • Page 56: Over-Voltage And Sneak-Current Protection

    Out-of-building installations of telephones or other standard (tip/ring) devices or terminals that connect to the G350 media modules require over-voltage and sneak current protection at both building entry points. Sneak current protectors must have a maximum of 350 mA and a minimum voltage rating of 600V.
