Cisco N7K-C7009-FAN Full English Description

Product Overview

Important Note: This fan tray is chassis-specific hardware and cannot be interchanged with fan assemblies for Nexus 7004, 7010, 7018 or any other Nexus platform. Individual fans inside the tray are not field-replaceable; the entire tray must be swapped if any internal fan fails. During fan tray removal, operators must complete replacement within several minutes. If cooling is lost for an extended period, the chassis triggers thermal protection shutdown to avoid 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 thermal load of installed modules. Fans run at low RPM under light workloads to minimize acoustic noise, and automatically increase airflow when internal temperatures rise. All thermal status metrics are reported to Cisco NX-OS for continuous environmental monitoring.
2. Side-to-Side Airflow Architecture

   Airflow Direction: Air intake from chassis right side → exhaust toward chassis left side. This native airflow design matches Nexus 7009 mechanical layout. Sufficient clearance must be reserved on both sides of the chassis to avoid blocking intake/exhaust vents, complying with standard hot-aisle / cold-aisle data center deployment standards.
3. OIR (Online Insertion and Removal) Support

   Technicians can replace the complete fan tray without powering off or rebooting the Nexus 7009 switch. Maintenance operations are carried out from the chassis rear panel, supporting non-disruptive servicing for mission-critical core data center networks. Proper ESD protection procedures are required during replacement.
4. Status LED & Remote Environmental Monitoring

   Built-in status LED on the fan tray rear panel provides instant local visual indication:

• Solid Green: All internal fans operate normally
• Solid Amber/Red: Fan fault detected
  NX-OS generates environmental syslog entries and sends SNMP traps to centralized monitoring systems immediately upon detection of fan abnormalities.

1. Internal Fan Redundancy Design

   Multiple independent fan units are integrated into a single tray assembly. If one fan malfunctions, remaining operational fans automatically ramp up speed to maintain temporary minimum cooling capacity. Administrators should arrange replacement promptly to eliminate thermal operation risks.
2. Data Center-Grade Reliability

   Industrial long-life bearing fan assembly engineered for 24/7 continuous operation in enterprise and carrier-grade data center core environments. Optimized to dissipate heat generated by high-density 10G / 40G Ethernet line cards, redundant supervisors and fabric modules.
