What Is the DS-C48V-48ITK9PRM?
The DS-C48V-48ITK9PRM is a specialized power module designed for Cisco Catalyst 9000 series switches, particularly supporting 48V infrastructure in high-density networking environments. This hardware component enables advanced features like IPsec encryption and WAN MACsec connectivity on Catalyst 9300X/9400X/9500X platforms. Its 48V architecture reduces power loss by 75% compared to traditional 12V systems while maintaining compatibility with Cisco’s EnergyWise technology.
Key Features & Technical Advantages
1. High-Efficiency 48V Power Delivery
- Reduces I²R losses by 16x through optimized voltage conversion
- Supports 192 simultaneous WAN MACsec sessions on Catalyst 9600X chassis
- Enables 55A+ charging capacity for mission-critical deployments
2. Enhanced Security Protocols
- Mandatory for enabling IPsec VPNs and MACsec Layer 2 encryption
- Requires HSEC K9 license activation per switch in stack configurations
- Supports zero-touch provisioning through Cisco DNA Center
3. Scalable Deployment
- Compatible with:
- Catalyst 9300X (up to 40G ports)
- Catalyst 9500X (1.6Tbps throughput)
- Catalyst 9600X (9.6Tbps backplane)
- Transparent rekeying during topology changes prevents traffic drops
Why Choose This 48V Solution?
Comparison: 12V vs 48V Architectures
| Metric | Traditional 12V | DS-C48V-48ITK9PRM |
|---|---|---|
| Power Loss | High (I²R dominant) | 6.25% of 12V systems |
| Cable Weight | 4x heavier | Space-optimized design |
| Encryption Support | Limited to 1G speeds | 100G MACsec-ready |
| Thermal Efficiency | 85°C max operating temp | 105°C tolerance |
The module’s modular power design allows gradual upgrades from legacy systems while maintaining backward compatibility with 12V peripherals. For organizations implementing SD-Access or intent-based networking, this component ensures <5ms latency for real-time applications.
