How to Install Cisco 16-Channel Voice and Video DSP Module

Installing the Cisco 16-Channel Voice and Video DSP Module is a straightforward upgrade that minimizes downtime and preserves router reliability. Follow these best-practice steps to ensure a secure and successful deployment in your ISR G2 chassis.

• Power down the Cisco router and disconnect it from power to prevent damage during installation. If you’re working within a live data center, follow your organization’s electrical safety procedures.
• Identify an available PVDM slot in the router chassis. Consult your device’s hardware guide to locate the correct slot type and orientation for the PVDM3-16 module.
• Align the PVDM3-16 module with the slot’s edge connectors and carefully insert it until it seats firmly. Ensure there is no excessive force and that connectors are fully engaged.
• Replace any retaining screws or fasteners as required by your chassis design. Reconnect power and boot the router, allowing the system to initialize the new module during startup.
• Verify recognition and health of the module using Cisco IOS commands such as show diag, show voice dsp, or show platform software status. Confirm that all 16 DSP channels are available for use and that there are no hardware errors.
• Configure media resources and features in IOS to enable the desired capabilities—conferencing, transcoding, transrating, or secure voice paths—according to your network requirements. Utilize appropriate QoS policies to guarantee performance for real-time media.
