Cisco FAN-MOD-6HS Full English Description

Product Overview

Important Note: This tray is chassis-specific hardware. It cannot be interchanged with FAN-MOD-6 (standard speed), FAN-MOD-3HS, FAN-MOD-4HS and other 6500/7600 series fan trays. Individual fans inside the tray arenot 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 risks permanent hardware damage caused by overheating. FAN-MOD-6HS is strongly recommended when deploying Supervisor 720 and high-power line cards to satisfy higher thermal dissipation requirements.

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 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.
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 Cisco 7606 / 7606-S chassis mechanical design, ensuring balanced heat dissipation for high-performance route processors and multi-gigabit interface modules. It fits standard rack deployments in service provider edge rooms and enterprise core wiring closets.
3. OIR (Online Insertion and Removal) Support

   Technicians can replace the whole fan tray without powering off or rebooting the Cisco 7606 / 7606-S router. Equipped with ergonomic handles and captive screws for convenient tool-free installation and removal, minimizing maintenance downtime for mission-critical IP/MPLS 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 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. Administrators should replace the fan tray promptly after detecting any fan failure to eliminate thermal single-point-of-failure risks.
2. Carrier-Grade Durability

   Industrial long-life fan assembly engineered for 24/7 continuous operation in service provider edge networks and large enterprise core environments. Optimized to dissipate heat generated by high-density multi-gigabit line cards.
