ASR1002HX-FAN= Overview and Functional Role

The ​​ASR1002HX-FAN=​​ is a dedicated fan module for Cisco’s ASR 1002-HX Router, engineered to ensure optimal thermal performance in high-density WAN edge deployments. This component is critical for maintaining ​​operational stability​​ and preventing overheating in environments with sustained traffic loads.

Technical Specifications and Design Features

• ​​Airflow Capacity​​: Delivers ​​120 CFM (cubic feet per minute)​​ to cool the router’s embedded services processor (ESP) and route processor (RP) modules.
• ​​Redundancy​​: Supports ​​N+1 fan redundancy​​, allowing continuous operation if one fan fails.
• ​​Noise Optimization​​: Operates at <55 dB for deployment in office-adjacent server rooms or retail spaces.
• ​​Compatibility​​: Exclusively designed for the ASR 1002-HX chassis running Cisco IOS XE 16.10.1 or later.

Why Thermal Management Is Non-Negotiable for ASR 1002-HX

​​Heat buildup​​ directly impacts hardware reliability. The ASR1002HX-FAN= mitigates risks by:

• ​​Preventing thermal shutdowns​​ during peak workloads, such as IPsec encryption or SD-WAN traffic bursts.
• ​​Extending hardware lifespan​​ by maintaining internal temperatures below 45°C (113°F), per Cisco’s operational guidelines.
• ​​Ensuring consistent performance​​ for latency-sensitive applications like VoIP or real-time analytics.

Key Deployment Scenarios

• ​​Branch Offices​​: Deploy in small footprints where airflow is restricted.
• ​​Retail SD-WAN Hubs​​: Maintain uptime for POS systems and inventory databases.
• ​​Temporary Networks​​: Use in pop-up sites (e.g., event venues) with limited cooling infrastructure.

Sourcing Authentic ASR1002HX-FAN= Modules

Third-party fan modules often lack Cisco’s thermal calibration, leading to false alerts or incompatibility. For guaranteed reliability:

• Verify ​​Cisco part numbers​​ via the Cisco Hardware Warranty Tracker.
• Purchase from authorized suppliers like ​​[“ASR1002HX-FAN=” link to (https://itmall.sale/product-category/cisco/)​​, which offers factory-tested modules with full warranty coverage.

The Cost of Overlooking “Boring” Components

During a healthcare network rollout, a client used non-Cisco fans to cut costs. Within six months, two ASR 1002-HX routers overheated during patient data backups, causing critical downtime. The ASR1002HX-FAN= isn’t just a fan—it’s a ​​predictability safeguard​​. While it won’t headline your network design, its absence will inevitably steal the show during outages. Always prioritize OEM thermal solutions; your SLAs depend on it.
