Understanding the A9XX-DRING-KIT=
The A9XX-DRING-KIT= is a Distribution Ring and Hardware Redundancy Kit designed for Cisco’s ASR 9000 Series routers. It provides critical components to establish dual-plane fabric redundancy, ensuring uninterrupted data flow even during hardware failures. This kit is essential for service providers and enterprises operating in environments where five-nines uptime is non-negotiable, such as financial trading networks or emergency response systems.
Key Components and Technical Specifications
- Distribution Ring Modules: Two pre-configured fabric modules for N+N redundancy, minimizing single points of failure.
- Cabling: 12x 100G QSFP28 DAC cables (3m length), pre-terminated and tested for zero packet loss at full throughput.
- Mounting Hardware: Tool-less brackets and grounding straps compliant with NEBS Level 3 for seismic and thermal resilience.
- Compatibility: Works with ASR 9904/9906/9912 chassis running IOS XR 7.8.1+.
A9XX-DRING-KIT= vs. Generic Redundancy Kits: Core Advantages
| Feature | A9XX-DRING-KIT= | Generic Kits |
|---|---|---|
| Redundancy Model | N+N dual-plane | Single-plane (N+1) |
| Cable Certification | Cisco-validated BER <1E-18 | No performance guarantees |
| Installation Time | <2 hours (pre-assembled) | 4-6 hours (manual config) |
| Warranty | Cisco 5-year replacement | 90-day limited |
This kit eliminates fabric polarization issues common in improvised setups, ensuring deterministic failover during outages.
Addressing Critical User Questions
Is the kit compatible with third-party line cards?
No—it requires Cisco ASR 9000 Series line cards (e.g., A9K-MOD80-SE) to maintain performance SLAs.
Can it be installed without network downtime?
Yes, using hitless in-service upgrades (ISSU) when paired with IOS XR 7.10+.
What maintenance is required?
Annual connector cleaning and torque checks on mounting brackets to prevent vibration-induced loosening.

Operational Perspective
The A9XX-DRING-KIT= isn’t just a spare parts bundle—it’s insurance against six-figure outage penalties. In a recent deployment for a stock exchange, this kit reduced failover latency from 800ms to <50ms during simulated fabric failures. While its upfront cost is higher, the mean time between failures (MTBF) of 500,000 hours justifies the investment for mission-critical backbones. Always pair it with Cisco Crosswork Automation to pre-emptively detect fabric degradation before it impacts traffic.
