Product Review

The Extreme 16508 switch offers a high-performance solution with an aggregated switch bandwidth of 88 Gbps and a frame forwarding rate of 65 Mpps, catering to environments demanding high throughput. While the provision of 24 PoE-plus ports, combined SFP and SFP+ options, and redundant power supply connectivity enhances flexibility and reliability for diverse network needs, the device is limited by its operating temperature range of 0° C to 45° C, which may not suit all deployment scenarios. Additionally, the PoE budget of 380W, while sufficient for many applications, might be restrictive when fully utilizing all PoE-plus ports with high-power devices.


The Extreme 16508 is a high-performance networking switch designed to meet the demands of modern enterprise networks. It features a comprehensive set of specifications that make it suitable for a wide range of applications, from small office environments to large data centers. At the core of its design, the Extreme 16508 offers 24 10/100/1000BASE-T PoE-plus ports, ensuring that devices connected to the network receive both data connectivity and power through a single cable. This capability simplifies the network infrastructure and reduces the need for additional power sources. Additionally, the switch includes 4 100/1000BASE-X (SFP) combo ports and 2 10GBASE-X SFP+ ports that support 1G/10G dual speed, providing flexibility for uplink or high-speed connections to other network devices or segments. The hardware is engineered for efficiency and performance, with an aggregated switch bandwidth of 88 Gbps and a frame forwarding rate of 65 Mpps. This ensures swift data processing and transmission across the network, minimizing latency and maximizing throughput. The switch's power efficiency is also notable, with a total power budget of 380W for PoE devices and an overall efficiency of 75%, making it an economical choice for powering devices such as VoIP phones, wireless access points, and surveillance cameras. Weighing 9.8 lb (4.475 kg) and sized for a 1RU rack space, the Extreme 16508 is compact and easy to integrate into existing rack environments. Its dimensions are specifically designed for ease of deployment and maintenance: - Height: 1.73 inches (4.4 cm) - Width: 17.4 inches (44.1 cm) - Depth: 10.0 inches (25.4 cm) The switch is equipped with a redundant power supply connector to ensure continuous operation, even in the event of a primary power supply failure. This feature is critical for networks where uptime is paramount. The power supply system is designed with an IEC 320 C14 input socket and supports a minimum 18AWG power cord gauge, ensuring reliable and safe power delivery.
  • 24 x 10/100/1000BASE-T PoE-plus (RJ45) ports, with 4 ports serving as combo ports alongside 4 SFP combo ports, provide flexibility in network design and connectivity.
