Product Features
Technical Overview
This switch operates at Gigabit Ethernet speeds (1000Base-T and 1000Base-X) across all ports, supporting both twisted pair and optical fiber media types. The 16 RJ-45 ports deliver PoE+ (802.3at) power, with a total budget of 120W to accommodate energy-intensive devices. Two SFP (mini-GBIC) expansion slots provide flexible uplink options for connecting to fiber networks or extending reach beyond copper limitations.
Layer 3 switching capabilities enable advanced routing protocols, quality of service (QoS), and access control lists (ACLs) for traffic management. The switch is fully manageable via a web interface or command-line interface, offering features like VLANs, link aggregation, and port mirroring for network monitoring and troubleshooting.
Relevant factors for this section include Total Number of Network Ports, Network (RJ-45), Uplink Port, Media Type Supported. When those points are considered together, they give buyers a clearer picture of how the product is equipped, how it fits into deployment, and what kind of day-to-day role it is meant to support.
