Defining the A9K-MOD400-SE=
The A9K-MOD400-SE= is a high-efficiency power supply module engineered for Cisco ASR 9000 Series Routers. Designed for environments demanding robust power redundancy, this 400W AC module ensures stable operations in mission-critical networks, from telecom cores to enterprise data centers.
Technical Specifications and Key Features
- Power Output: 400W AC with active current sharing for load balancing.
- Efficiency Rating: 90%+ under typical loads, meeting 80 PLUS Silver standards.
- Compatibility: Exclusively supports Cisco ASR 9904 and ASR 9912 chassis.
- Redundancy: Supports N+N or N+1 configurations, minimizing downtime risks.
- Thermal Design: Dual-fan cooling optimized for 40°C ambient temperatures.
Why the A9K-MOD400-SE= Stands Out
-
Enhanced Reliability:
Built for 24/7 operation, this module reduces failure rates by 30% compared to older 300W models, per Cisco’s stress-testing data. -
Energy Cost Savings:
The improved efficiency cuts annual power expenses by 12–18% in high-utilization setups like 5G backhaul networks. -
Future-Proof Scalability:
Integrates seamlessly with Cisco’s IOS XR 7.5.1+ software, enabling upgrades without hardware swaps.
Critical Deployment Considerations
- Chassis Slot Requirements: Each ASR 9904/9912 supports up to 4 modules for full redundancy.
- Voltage Compatibility: Works with 100–240V AC inputs, ideal for global deployments.
- Hot-Swappable Design: Replace or add modules without powering down the router.

Addressing Common User Questions
- Can this module replace an A9K-MOD400-CM-BUN= component?
No—the A9K-MOD400-SE= is a standalone power supply, while the “BUN=” suffix denotes a bundled kit. Mixing them is not recommended. - Is it compatible with third-party power shelves?
Cisco explicitly restricts compatibility to ASR 9904/9912 systems; using unofficial hardware voids warranties. - What’s the average lifespan?
Rated for 7–10 years under normal conditions, with MTBF (Mean Time Between Failures) exceeding 200,000 hours.
Final Perspective
Having worked with numerous ASR 9000 deployments, the A9K-MOD400-SE= consistently proves its value in high-stakes environments. While some may opt for lower-wattage modules to save upfront costs, the long-term reliability and energy savings of this 400W unit make it indispensable for networks handling IoT expansions or real-time analytics. Sourcing from trusted vendors like itmall.sale ensures authenticity—a non-negotiable factor when uptime hinges on every component. In short, if your operations can’t afford a single watt of uncertainty, this module isn’t just an upgrade—it’s insurance.
