How to install Cisco 32-Channel Voice and Video DSP Module

• Preparation: Power down the Cisco ISR Gen2 router and follow your organization’s electrostatic discharge (ESD) guidelines. Confirm you have the correct slot and that the router is in a safe maintenance window.
• Remove cover and access slot: Remove the router cover as required to access the DSP module slots and identify the appropriate PVDM slot within the chassis according to your hardware guide.
• Align and insert: Carefully align the PVDM3-32 module with the backplane connectors, ensuring straight and gentle seating to avoid bent pins or misalignment. Gently slide the module into the slot until it is firmly seated.
• Secure and verify: Fasten any retaining screws or latches as specified by Cisco hardware guidelines. Reinstall the chassis cover and reconnect power. Power on the router and verify the module is recognized in the system.
• Initial configuration: Access the Cisco IOS CLI and enable the PVDM3-32 through the appropriate commands. Configure media resources, codec policies, and conferencing or transcoding options in line with your network requirements.
• Quality and scaling checks: Run baseline tests for voice quality, conferencing capacity, and media transcoding to confirm expected performance. Tune QoS, classification, and routing as needed.
