​​ASR-9904-AC= Overview: Core Functionality​​

The ​​ASR-9904-AC=​​ is a ​​3000W AC power supply module​​ designed for Cisco’s ASR 9904 Router, providing scalable and redundant power for high-density service provider and enterprise core networks. It supports ​​dual AC inputs​​ (200–240V) with hot-swappable functionality, ensuring continuous operation during maintenance or grid instability.

​​Key Technical Advantages​​

• ​​Redundancy​​: Enables ​​N+N power redundancy​​ for mission-critical deployments, eliminating single points of failure.
• ​​Energy Efficiency​​: Operates at ​​>90% efficiency​​, reducing operational costs and thermal load in data centers.
• ​​Scalability​​: Supports incremental power upgrades to accommodate additional line cards or service blades.

​​Primary Deployment Scenarios​​

• ​​Telecom Core Networks​​: Powers 100G/400G routing for 5G backhaul and IP/MPLS traffic aggregation.
• ​​Hyperscale Data Centers​​: Ensures stable power for high-throughput interconnects and cloud gateways.
• ​​Financial Trading Hubs​​: Delivers fault-tolerant energy for latency-sensitive transaction systems.

​​Addressing Critical User Concerns​​

​​Q: Can this module support mixed AC/DC configurations in the same chassis?​​

No. The ASR-9904-AC= is ​​AC-exclusive​​ and incompatible with DC power supplies. Mixing power types risks hardware damage and voids warranties.

​​Q: How does it differ from the ASR-9904-DC= model?​​

The AC= variant uses ​​standard AC power inputs​​, while the DC= model supports -48V DC for telecom or industrial environments.

​​Procurement and Compatibility Checks​​

The ASR-9904-AC= is available through Cisco-authorized partners like [“ASR-9904-AC=” link to (https://itmall.sale/product-category/cisco/). Verify rack power capacity and circuit breaker ratings (30A minimum per module) before deployment.

​​Why This Power Supply Defines Operational Resilience​​

In a decade of deploying core network infrastructure, I’ve observed that ​​power redundancy separates functional networks from unbreakable ones​​. The ASR-9904-AC= isn’t just about keeping routers online—it’s about ensuring that during grid failures, maintenance, or cyberattacks on power grids, traffic flows uninterrupted. For teams managing infrastructure where downtime equates to reputational collapse, this module isn’t optional—it’s the bedrock of trust in digital ecosystems.
