Cisco WS-C6K-9SLOT-FAN Full English Description

Product Overview

Important Note: This standard-speed fan tray officially supportsSupervisor Engine 1 and Supervisor Engine 2 only. It cannot satisfy thermal requirements of Supervisor Engine 32 or Supervisor Engine 720; WS-C6K-9SLOT-FAN2 is mandatory for these high-performance supervisors. Individual fans inside the tray are not field-replaceable, the entire tray must be replaced once any internal fan fails. It is incompatible with Catalyst 6509-E enhanced chassis. Operating equipment without a functional fan tray triggers critical thermal alarms and may result in permanent hardware overheating damage.

Key Features

1. Intelligent Variable-Speed Thermal Regulation

   The fan tray dynamically adjusts fan rotational speed based on real-time chassis temperature, operating altitude and network forwarding workload. It runs at low RPM under light traffic loads to minimize acoustic noise, and accelerates automatically under high-temperature conditions. Real-time thermal telemetry is transmitted to Cisco IOS for continuous environmental monitoring. Maximum airflow capacity reaches212 CFM.
2. Side-to-Side Airflow Architecture

   Airflow Direction: Right-side intake → Left-side exhaust when facing the chassis front panel. This native cooling layout matches Catalyst 6009 / 6509 non-E mechanical structure, providing balanced heat dissipation for early-generation supervisors and gigabit line cards. Optimized for standard rack deployment within enterprise wiring closets and campus distribution rooms.
3. OIR (Online Insertion and Removal) Support

   Technicians can replace the complete fan tray without powering off or rebooting Catalyst 6009 / 6509 switch. Equipped with an ergonomic front handle and captive screws for tool-free installation and removal, effectively cutting maintenance downtime for enterprise campus networks.
4. Front Panel Visual Status LED & Remote Monitoring

   Status LED on the front face 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 generates environmental event logs and sends SNMP traps to centralized monitoring systems immediately upon fan fault detection.

1. Built-In Multi-Fan Redundancy

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

   Long-life industrial bearing fan assembly engineered for 24/7 continuous operation in legacy enterprise campus networks. Optimized to dissipate heat generated by low and medium thermal-load copper and optical interface modules.
