Product Review

The Cisco N5K-C5696-FAN-B, with its back-to-front airflow (port side exhaust) and two fans, ensures efficient thermal management for high-performance environments. It supports 10 Gigabit Ethernet SFP+ copper Twinax cables, offering compatibility with various optical interface types (gXENPAK, X2, XFP) and boasts the lowest power consumption among devices of its class, with hot-swappable functionality for minimal downtime. However, its power requirements, with an operating power of 480W and a maximum of 750W, alongside a physical depth of 30.0 inches, may pose installation and energy consumption considerations for some deployments.


The Cisco N5K-C5696-FAN-B is a network fan module designed to provide cooling for Cisco networking devices. It features back-to-front airflow, ensuring that air is drawn from the back and expelled out the front (port side), aligning with the thermal designs of many data centers and promoting efficient cooling. This module is equipped with two fans, enhancing the redundancy and reliability of the system's cooling capabilities. One of the notable aspects of the N5K-C5696-FAN-B is its compatibility with 10 Gigabit Ethernet SFP+ copper Twinax cables, which are the smallest 10 Gigabit Ethernet form-factor available. This compatibility ensures the module can support high-speed data transfer needs while maintaining a compact footprint. Additionally, it offers optical interoperability with various interface types such as gXENPAK, X2, and XFP, widening its application range across different network setups. The device stands out for its low power consumption, with a typical operating power of 480W and a maximum power of 750W. This efficiency is supported by an input voltage range of 180–264 VAC and a frequency range of 47–63Hz. Notably, the device maintains an efficiency of 90% or better at full load, which it sustains down to a 25% load, marking it as an energy-efficient choice for networking environments. As a hot-swappable device, the N5K-C5696-FAN-B allows for easy replacement and maintenance without the need to power down the network system, minimizing downtime and ensuring continuous operation. This feature is critical for maintaining network reliability and performance in dynamic and demanding environments. The module is compliant with the Restriction of Hazardous Substances (RoHS), indicating its adherence to environmental and health standards by minimizing the use of hazardous materials. It also boasts a heat dissipation capacity of 2566 BTU/hr, effectively managing the thermal output and maintaining optimal operating conditions. Physically, the device measures 3.47 inches in height, 17.3 inches in width, and 30.0 inches in depth, making it a manageable size for installation in a variety of network racks and cabinets. - Operating temperature ranges from 0°C (32°F) to 40°C (104°F), and non-operating temperature ranges from –40°C (-40°F) to 70°C (158°F), accommodating various environmental conditions. - Humidity tolerance spans from 5% (non-condensing) to 95% (non-condensing), ensuring performance stability in both dry and humid conditions. - The unit can operate effectively at altitudes from 0 ft to 10,000 ft (0 m to 300 m), making it versatile for deployment in different geographic locations. In summary, the Cisco N5K-C5696-FAN-B is a high-efficiency, hot-swappable fan module that supports 10 Gigabit Ethernet SFP+ connections and is compatible with various optical interface types. It is designed for energy efficiency, with a notable reduction in power consumption, and complies with RoHS standards.
