Cisco C4506-E-FAN Full English Description

Product Overview

Important Note: This fan tray is chassis-specific hardware. It cannot be interchanged with C4503-E-FAN, C4507R-E-FAN or C4510R-E-FAN. Individual fans inside the tray are not field-replaceable. The whole fan tray must be replaced once any internal fan fails. Operating the switch without an installed fan tray triggers critical thermal alarms and may cause permanent hardware overheating damage.

Key Features

1. Intelligent Variable-Speed Thermal Regulation

   The fan tray dynamically adjusts rotational speed based on real-time chassis temperature and network workload. It operates at low RPM under light traffic loads to reduce acoustic noise, and automatically increases airflow during high-temperature operating conditions. Real-time thermal status data is transmitted to the Cisco IOS operating system for continuous environmental monitoring.
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 the Catalyst 4506-E chassis design, suitable for mainstream enterprise wiring closet rack deployments. It guarantees uniform heat dissipation for PoE-enabled line cards and supervisor modules.
3. OIR (Online Insertion and Removal) Support

   Technicians can replace the entire fan tray without powering off or rebooting the Catalyst 4506-E switch. Equipped with ergonomic handles, it supports convenient installation and removal to minimize maintenance downtime for campus distribution and access networks.
4. Front Panel Visual Status LED & Remote Monitoring

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

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

1. Built-In Multi-Fan Redundancy

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

   Industrial long-life fan assembly engineered for 24/7 continuous operation in enterprise campus networks. Optimized to dissipate heat generated by multi-gigabit line cards and high-power PoE modules.
