Product Review

The Extreme 16404 switch offers a total of 52 Gigabit Ethernet ports and 6 10Gigabit Ethernet ports, supporting a wide range of connectivity options for high-density environments. With an aggregated switch bandwidth of 224 Gbps and a frame forwarding rate of 166.7 Mpps, it ensures efficient handling of network traffic. However, its power consumption and heat dissipation, peaking at 1010 W and 3446 BTU/hr respectively with dual PSUs, might pose challenges for energy-sensitive deployments.


The Extreme 16404 is a high-performance networking switch designed to meet the demands of modern data centers and enterprise networks. This switch offers a blend of Gigabit Ethernet (GbE) and 10 Gigabit Ethernet (10GbE) ports, providing flexible connectivity options for a wide range of applications. With a maximum of 52 active GbE ports and 6 active 10GbE ports, the Extreme 16404 can handle substantial data throughput, making it suitable for high-density environments. Key hardware specifications include an aggregated switch bandwidth of 224 Gbps and a frame forwarding rate of 166.7 million packets per second (Mpps), ensuring efficient handling of network traffic even under heavy load. The switch features 48 ports of 10/100/1000BASE-T Power over Ethernet Plus (PoE+), enabling it to power devices such as IP cameras, VoIP phones, and wireless access points directly through the network cables, simplifying deployment and reducing cabling requirements. Additionally, the Extreme 16404 offers: - 4 unpopulated 100/1000BASE-X Small Form-factor Pluggable (SFP) ports for fiber connectivity, allowing for extended network reach and uplink redundancy. - A serial console port for local management, a 10/100BASE-T out-of-band management port for remote management, and a USB port for external storage or firmware updates, enhancing the device's usability and management flexibility. - A compact form factor with dimensions of 1 Rack Unit (RU) height, 17.4 inches in width, and 17.0 inches in depth, making it suitable for installation in standard equipment racks. The switch's power efficiency is demonstrated by its minimum and maximum power consumption ratings of 493W and 505W per Power Supply Unit (PSU) respectively, with dual PSU configurations doubling these figures. Heat dissipation is managed efficiently, with values ranging from 221 W to 250 W per PSU, ensuring reliable operation without excessive thermal output. The Power over Ethernet (PoE) capabilities are particularly noteworthy, with a total PoE power budget of 380 W with a single PSU and 760 W with dual PSUs, providing ample power for attached devices across all PoE-enabled ports. Designed to operate in a variety of environmental conditions, the Extreme 16404 can function in temperatures from 0° C to 40° C, withstand humidity levels from 10% to 95% relative humidity (non-condensing), and operate at altitudes up to 3,000 meters.
