Cisco ASR-9006-FAN Full English Description

Product Overview

Important Note: Both fan slots in one chassis must use the same generation fan trays (mixing V1 and V2 is unsupported). OIR (Online Insertion and Removal) is supported under defined ambient temperature constraints. Complete fan tray replacement must be finished within 5 minutes after removal to avoid chassis thermal protection shutdown. Standard ESD anti-static handling procedures must be followed during installation and removal. This fan tray cannot be used for ASR-9001, ASR-9010, ASR9900 series or other ASR9k router models.

Key Features

1. Intelligent Variable-Speed Thermal Regulation

   The fan tray dynamically adjusts rotor rotational speed based on real-time internal chassis temperature, operating altitude and overall system thermal load. Fans operate at low RPM under light traffic loads to reduce power consumption and acoustic noise, and automatically accelerate to increase airflow when internal temperatures rise. All environmental telemetry data is uploaded to IOS XR for unified environmental monitoring.
2. Chassis Airflow Architecture

   Cool air enters from the side intake of the ASR 9006 chassis, and hot exhaust air flows toward the rear of the chassis. Maintain sufficient unobstructed clearance around rack ventilation openings to avoid airflow blockage and prevent thermal hotspots.
3. OIR (Online Insertion and Removal) Support

   Engineers can perform fan tray replacement while the router remains powered and forwards live traffic. Operators must strictly comply with the 5-minute maintenance time limit to prevent over-temperature protection shutdown.
4. Visual Status LED & Remote Monitoring

   Front panel status LED provides intuitive local status indication:

• Solid Green: All internal fan rotors operate normally
• Solid Amber/Red: Fan fault or over-temperature alarm triggered
  IOS XR generates syslog entries and sends SNMP traps to centralized monitoring platforms immediately once fan anomalies are detected.

1. N+1 Internal Fan Redundancy

   Multiple independent fan rotors are integrated into a single tray assembly. If one rotor fails, remaining fans supply temporary partial cooling capacity. Administrators should arrange FRU replacement promptly to eliminate thermal operational risks. The chassis requires two working fan trays for full cooling redundancy.
2. Carrier-Grade Reliability

   Industrial brushless DC fan assembly engineered for 24/7 continuous operation within service provider core, aggregation and mobile backhaul routing environments.
