Cisco WS-C6509-E-FAN Full English Description

Product Overview

Important Note: This fan tray is chassis-specific hardware andcannot be interchanged with WS-C6K-9SLOT-FAN / WS-C6K-9SLOT-FAN2 for standard non-E Catalyst 6509 chassis, nor other Catalyst 6500-E series fan trays. Individual fans inside the tray are not field-replaceable; the entire tray must be replaced once any internal fan fails. Operating the chassis without a properly installed fan tray triggers critical thermal alarms and may cause permanent hardware damage caused by overheating. A minimum 2500W power supply is required to power WS-C6509-E-FAN.

Key Features

1. Intelligent Variable-Speed Thermal Regulation

   The fan tray dynamically adjusts fan rotational speed based on real-time chassis internal temperature, operating altitude and network forwarding workload. It runs at low RPM under light traffic loads to reduce acoustic noise and automatically boosts airflow under high-temperature operating conditions. Real-time thermal telemetry is transmitted to Cisco IOS for continuous environmental monitoring. Maximum airflow capacity reaches846 CFMat full operating speed.
2. Side-to-Side Airflow Architecture

   Airflow Direction: Right-side intake → Left-side exhaust when facing the chassis front panel. This native thermal layout matches Catalyst 6509-E mechanical design, ensuring balanced heat dissipation for redundant supervisors, multi-gigabit line cards and high-power service modules. Optimized for standard rack deployments within enterprise wiring closets and data center core aggregation rooms.
3. OIR (Online Insertion and Removal) Support

   Technicians can replace the complete fan tray without powering off or rebooting the Catalyst 6509-E switch. Equipped with ergonomic front handle and captive screws for tool-free installation and removal, minimizing maintenance downtime for mission-critical campus core networks.
4. Front Panel Visual Status LED & Remote Monitoring

   Status LED located on the front face of the fan tray provides instant local visual feedback:

• Solid Green: All internal fans operate normally
• Solid Red: One or more internal fans stall or encounter hardware faults
  Cisco IOS records environmental event logs and sends SNMP traps to centralized monitoring systems immediately upon fan fault detection.

1. Built-In Multi-Fan Redundancy

   Nine independent fans are integrated within one tray. If a single fan malfunctions, remaining functional fans automatically ramp up speed to sustain basic cooling capacity. Administrators should replace the fan tray promptly after detecting any fan failure to eliminate thermal single-point-of-failure risks.
2. Enterprise-Grade Durability

   Industrial long-life bearing fan assembly engineered for 24/7 continuous operation in large enterprise campus core networks. Optimized to dissipate heat generated by high-density copper/SFP optical line cards, distributed forwarding modules and high-power service modules.
