Cisco WS-C6503-E-FAN Full English Description

Product Overview

Important Note: This tray is chassis-specific hardware andcannot be installed on the standard Catalyst 6503 chassis. It is incompatible with FAN-MOD-3 and FAN-MOD-3HS (these two fan trays are dedicated for non-E Catalyst 6503). Individual fans inside the tray are not field-replaceable; the entire tray must be replaced once any internal fan fails. Operating the chassis without an installed fan tray triggers critical thermal alarms and may lead to permanent hardware damage caused by overheating.

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 operates 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. It supports dual-speed operation to balance noise performance and cooling capacity.
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 6503-E chassis mechanical design, guaranteeing balanced heat dissipation for high-performance supervisors and multi-gigabit line cards. Suitable for standard rack deployments in enterprise wiring closets and data center aggregation rooms.
3. OIR (Online Insertion and Removal) Support

   Technicians can replace the whole fan tray without powering off or rebooting the Catalyst 6503-E switch. Equipped with ergonomic handles and captive screws for convenient tool-free installation and removal, minimizing maintenance downtime for mission-critical campus networks.
4. Front Panel Visual Status LED & Remote Monitoring

   Status LED 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 after fan faults are detected.

1. Built-In Multi-Fan Redundancy

   Multiple independent fans are integrated within one tray. If a single fan fails, 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 enterprise campus distribution networks. Optimized to dissipate heat generated by high-density copper and optical line cards, as well as PoE hardware modules.
