Product Review

The Extreme 16509 switch offers a solid aggregated switch bandwidth of 136 Gbps and a frame forwarding rate of 101 Mpps, providing efficient handling of network traffic for medium-sized networks. However, its operational noise levels can reach up to 55 dB(A) under high-speed operations, which might be a consideration for environments where noise is a concern. With a range of port options including 48 x 10/100/1000BASE-T RJ45 ports and 2 x 10GBASE-X SFP+ ports, it supports versatile connectivity but lacks built-in redundancy for its power supply, which could be a critical downside for mission-critical applications.
