Longshine LCS-GS9420 Managed network switch

Gigabit 16x Port Switch, 4x SFP, QoS, Full Duplex Easily boosting your networking throughput, the GS9420 & GS9428 16/24-Ports Gigabit Web Smart
Switch provides you 16/24 10/100/1000Mbps gigabit ports that lead you to a real gigabit connection.
Users are now able to transfer high bandwidth-demanded files faster and get a real efficiency
improvement with the user-friendly Web-based management interface. This product also equips 4 mini GBIC slots for your flexible fiber connection. Use of the mini-GBIC port disables the connection of its corresponding copper port automatically.
The management functionalities provide efficient network usage. VLAN reduces the collisions from
widely broadcasting. Port Aggregation enlarges the bandwidth of backbone connection. QoS is
supported to secure the bandwidth for some bandwidth-demanded applications including VoIP or
videoconference. The 802.3x and backpressure flow control mechanisms are also supported to
ensure the correctness of data transmitting.
