Decoding the SKU: Understanding IR-PWR-G2A-CN=...
Core Specifications and Design Philosophy
The Cisco ASR-9006-AC-V2 is a 6-slot aggregation router engineered for multi-terabit throughput and AC power redundancy, designed for service providers and enterprises demanding carrier-grade reliability. Key technical parameters include:
- Power Supply: Dual 100–240V AC inputs with 99.999% uptime, reducing energy costs by 18% compared to DC variants.
- Port Density: Supports 32x100G interfaces per slot via modular A900-IMA1C (100GE CPAK) optics, enabling seamless integration with legacy and next-gen infrastructure.
- Environmental Resilience: Operates at -10°C to 55°C with an IP54-rated chassis, ideal for industrial deployments.
- Forwarding Capacity: 3.6 Tbps per slot using Cisco’s Quantum Flow Processor and Tomahawk-based line cards, optimized for high-density traffic handling.
Technical Innovations Over Legacy DC Models
AC Power Efficiency and Infrastructure Compatibility
The ASR-9006-AC-V2 eliminates DC grid dependency and AC/DC conversion losses, achieving 15–20% lower total cost of ownership (TCO) over five years compared to the ASR-9006-DC. Adaptive power scaling dynamically adjusts energy consumption based on traffic loads, critical for data centers and IoT edge networks.
VoQ Architecture for Congestion-Free Traffic
Leveraging Virtual Output Queuing (VoQ) and Cisco’s Fabric Interface Adapter (FIA), the router prevents head-of-line blocking through credit-based scheduling. This ensures low latency for applications like 5G backhaul and autonomous vehicle V2X communication.
SDN Readiness and Multi-Vendor Interoperability
The router supports EVPN/VXLAN for hybrid cloud deployments and integrates with Juniper MX240 and Huawei NE40E-X2-M8A routers, enabling seamless multi-vendor SDN ecosystems.
ASR-9006-AC-V2 vs. ASR-9006-DC: Critical Comparison
| Feature | ASR-9006-AC-V2 | ASR-9006-DC (Legacy) |
|---|---|---|
| Power Efficiency | 1800W adaptive scaling | 2100W fixed draw |
| Cooling System | 40% improved airflow | Standard thermal design |
| Deployment Cost | Lower TCO over 5 years | Higher maintenance |
| SDN Compatibility | EVPN/VXLAN-ready | Limited programmability |
Addressing Key Deployment Questions
Q: Why prioritize AC power in modern network upgrades?
A: AC infrastructure is globally standardized, simplifying deployment in regions without DC grids. The dual redundant modules ensure zero downtime during power fluctuations, aligning with SLAs for healthcare and utilities.
Q: How does it handle 100G traffic in high-density environments?
A: The Tomahawk line cards integrate 32x100G ports with 12 MB deep buffers per port. Combined with VoQ scheduling, this prevents packet loss in scenarios like 4K video streaming or IoT edge data aggregation.
Q: Is it backward-compatible with older ASR 9000 Series modules?
A: Yes. The AC-V2 supports legacy cards like the A900-IMA1C (100GE CPAK), enabling cost-effective upgrades from ASR-9006-DC deployments without chassis replacement.
For enterprises prioritizing energy efficiency, terabit scalability, and regulatory compliance, the ASR-9006-AC-V2 stands as a future-proof solution for smart cities and hyperscale cloud networks. Its modular architecture and SDN adaptability make it indispensable for next-gen applications.
