What Is the ASR1000X-AC-1100W=?
The ASR1000X-AC-1100W= is a high-efficiency AC power supply module designed for Cisco’s ASR 1000X Series routers, which are widely deployed in enterprise WAN and service provider edge networks. This module delivers 1100 watts of reliable power to support bandwidth-intensive applications like SD-WAN, encrypted VPNs, and high-density 10G/40G interfaces.
Core Technical Features
- 90%+ operational efficiency: Reduces energy waste and heat generation, critical for always-on deployments.
- Hot-swappable design: Enables replacement without shutting down the router, ensuring zero service disruption.
- Universal input voltage (100-240V AC): Compatible with global power standards, ideal for distributed networks.
ASR1000X-AC-1100W= vs DC Power Supplies: Key Differences
| Factor | ASR1000X-AC-1100W= | DC Power Modules |
|---|---|---|
| Infrastructure Needs | Plug-and-play with AC grids | Requires DC battery systems |
| Deployment Speed | Minutes | Hours (wiring/cabling) |
| Cost Efficiency | Lower upfront investment | Higher infrastructure costs |
Addressing Critical User Questions
Q: Can this module support redundant power configurations?
Yes. The ASR1000X-AC-1100W= supports N+1 redundancy when paired with a second unit, eliminating single points of failure.
Q: Is it compatible with all ASR 1000X chassis models?
The module works with ASR 1001-X, ASR 1002-X, and ASR 1006-X routers running Cisco IOS XE 3.18 or later.
Q: How does it handle voltage fluctuations or surges?
Built-in active power factor correction (PFC) stabilizes input voltage, protecting against grid inconsistencies and reducing harmonic distortion.
