ASR1000X-DC-950W=: How Does This Power Supply Ensure Cisco ASR 1000X Router Stability?

​​Defining the ASR1000X-DC-950W=​​

The ​​ASR1000X-DC-950W=​​ is a ​​high-efficiency DC power supply​​ engineered for the ​​Cisco ASR 1000X Series routers​​, platforms widely deployed in enterprise WAN edges, SD-WAN hubs, and mid-sized data centers. This unit provides ​​950W of 48V DC power​​ with 1+1 redundancy capabilities, ensuring uninterrupted operation for critical routing and security services.

​​Core Technical Specifications​​

• ​​Input Voltage​​: Accepts ​​–40 to –72 VDC​​ for compatibility with telecom-grade power plants.
• ​​Efficiency​​: Operates at ​​94% efficiency​​ (80 Plus Platinum equivalent) under typical loads.
• ​​Redundancy​​: Supports ​​N+N parallel configurations​​ for fault-tolerant deployments.
• ​​Compatibility​​: Designed for ​​ASR 1001-X, 1002-X, and 1006-X chassis​​ running ​​Cisco IOS XE 17.3+​​.

​​Why Power Integrity Matters for ASR 1000X Routers​​

1. ​​Service Continuity​​: Prevents downtime in ​​SD-WAN TLOC/IPsec​​ or ​​Cisco Umbrella SIG​​-enabled routers during grid fluctuations.
2. ​​Density Support​​: Powers fully populated chassis with ​​ESP100-X modules​​, ​​8x10G line cards​​, and ​​USB 3.0 supervisors​​ simultaneously.
3. ​​Sustainability​​: Reduces heat waste by ​​18%​​ compared to older 750W models, lowering cooling costs.

​​Addressing Deployment Concerns​​

​​Q1: Can this supply replace AC power modules in existing ASR 1002-X routers?​​
A1: No. The ​​ASR1000X-DC-950W=​​ is ​​DC-only​​ and requires a chassis originally configured for DC input. AC/DC chassis conversions are unsupported.

​​Q2: How does redundancy work during a power supply failure?​​
A2: In ​​1+1 mode​​, the surviving unit instantly assumes full load without service interruption. SNMP traps alert admins to replace the failed unit.

​​Q3: What maintenance ensures long-term reliability?​​
A3: Cisco recommends ​​annual terminal cleaning​​ and firmware updates via ​​Cisco Crosswork Network Controller​​ to optimize voltage regulation.

​​Procuring Genuine ASR1000X-DC-950W= Units​​

For assured safety and compliance, purchase the ​​ASR1000X-DC-950W=​​ exclusively from itmall.sale’s Cisco ASR 1000X catalog. Counterfeit units often lack proper current-limiting safeguards, risking chassis damage.

​​Practical Observations from the Field​​

In SD-WAN deployments spanning remote mining sites and offshore rigs, I’ve seen ​​DC power stability​​ make or break network uptime. The ​​ASR1000X-DC-950W=​​ isn’t just a “power brick”—it’s the ​​cornerstone of resilience​​ in environments where AC grids are unreliable. Using undersized or non-redundant supplies here is akin to fueling a jet with diesel: the system might limp along, but failure during ascent (or peak traffic) is inevitable. Prioritize power design as rigorously as routing protocols.
