Product Review

The Cisco N9K-C9508-B2 excels in scalability and flexibility, offering a modular design that includes a Supervisor Module, Power Supplies, System Controllers, Fan Trays, and six Fabric Modules, catering to complex networking needs. However, its large form factor, requiring a 13U rack space, might be a drawback for environments with limited space. Additionally, while it supports Layer 3, the absence of PoE ports limits its application in environments requiring power over Ethernet for devices.


The Cisco N9K-C9508-B2 is a modular, rack-mountable networking device designed for high-performance computing environments. This unit is tailored for Layer 3 networking and fits in a 13U space in standard equipment racks, with dimensions of 22.7 inches in height, 17.5 inches in width, and 30 inches in depth. The design prioritizes scalability and reliability, making it suitable for data centers requiring efficient space utilization and high-speed data processing capabilities. At the heart of the N9K-C9508-B2 is the Supervisor Module, of which there is one, labeled as N9K-SUP-A. This module is critical for managing the overall operation of the device, including data traffic control and system management tasks. The unit is equipped with three AC power supplies ensuring redundancy and continuous operation even in the event of a power supply failure. The power supply type is AC, adhering to common data center power infrastructure standards. For enhanced system management and reliability, the device includes two system controllers of the N9K-SC-A type. These controllers work in tandem to facilitate system health monitoring, configuration management, and troubleshooting, thereby ensuring optimal performance and uptime. Cooling is managed by three fan trays that maintain operational temperatures within safe limits, crucial for the longevity and reliability of the device's components. The Cisco N9K-C9508-B2 is designed to support high-density networking with six fabric modules, enhancing its capability to handle vast amounts of data traffic seamlessly. This setup is pivotal for environments demanding high data throughput and minimal latency. The device boasts 18 expansion slots that accommodate a mix of Switch Fabric, Supervisor Engine, and Line Card modules, providing flexibility in configuration for varied networking requirements.
  • No PoE (RJ-45) Port
  • No Token Ring Port
  • No LRE Port
However, the device does come equipped with USB and management ports, facilitating easier device management and configuration updates. The inclusion of management features such as VLAN, RMON, Syslog, SNMP v1, 2, 3; Telnet; and CLI support enhances the manageability of the device, allowing for comprehensive monitoring and control over network operations. Rack mount brackets are included with the Cisco N9K-C9508-B2, ensuring easy installation in standard equipment racks.
