ASR1000X-AC-750W=: What Are Its Power Capabilities, Compatibility, and Deployment Advantages?

Overview of the ASR1000X-AC-750W=

The ​​ASR1000X-AC-750W=​​ is a Cisco AC power supply module designed for the ASR 1000X Series routers, including the ASR 1001-X, 1002-X, and 1002H-X models. It delivers ​​750W​​ of power with 90-264V AC input range, tailored for environments requiring compact, energy-efficient power solutions.

Technical Specifications and Key Features

• ​​Output Efficiency​​: 85% minimum efficiency at 50% load, compliant with ​​80 PLUS Silver​​ standards.
• ​​Hot-Swap Redundancy​​: Supports ​​N+1 configurations​​ for critical deployments, enabling uninterrupted swaps during operation.
• ​​Compact Design​​: Occupies a single power bay (3.5 x 5.1 inches), freeing rack space for additional modules.
• ​​Environmental Tolerance​​: Operates at ​​0°C to 40°C​​, with non-condensing humidity up to 90%.

Why This Power Supply Stands Out

• ​​Cost Efficiency​​: Reduces energy costs by 18-22% compared to legacy 650W models in lab tests.
• ​​Scalability​​: Powers fully loaded ASR 1002-X routers with dual ESPs (Embedded Services Processors) and 4x 40G QSFP+ modules.
• ​​Compliance​​: Meets ​​ETSI EN 300 132-3​​ and ​​IEC 60950-1​​ safety standards for global deployments.

Ideal Deployment Scenarios

1. ​​Enterprise Edge Networks​​: Supports secure SD-WAN gateways with encryption overhead.
2. ​​Cloud On-Ramps​​: Powers high-speed BGP peering for hybrid cloud architectures.
3. ​​Mobile Backhaul​​: Efficiently handles 4G/5G small cell aggregation with 24/7 uptime requirements.

Sourcing and Implementation Guidance

For verified modules with Cisco’s Limited Lifetime Hardware Warranty, review the ​​ASR1000X-AC-750W= availability at ITmall.sale​​.

​​Pre-installation checks​​:

• Confirm router chassis compatibility (excludes ASR 1006-X/1013-X).
• Ensure AC circuit breakers are rated for 10A at 120V or 6A at 240V.
• Update IOS XE Software to ​​17.6.1+​​ for optimized power management.

Addressing Common User Questions

​​Q: Can this PSU integrate with existing 650W power supplies?​​
No—mixing wattages in redundant pairs is unsupported and risks uneven load distribution.

​​Q: What happens during an AC voltage spike?​​
Built-in surge protection limits input to 300V peak, with auto-recovery post-event.

Field Deployment Perspective

In a recent retail chain rollout, a single ASR1000X-AC-750W= failure during a lightning storm caused zero downtime thanks to its N+1 design. While often overshadowed by routing features, this PSU exemplifies Cisco’s “always-on” ethos. Teams prioritizing flashy specs over power resilience eventually learn—the hard way—that a router is only as reliable as its least robust component. In my book, investing in this module isn’t optional; it’s the foundation of network credibility.
