4-PortGigabit Switch

In today’s enterprise environments that require more advanced processing, the GS400 4-portgigabit switch is the best switching hub solution for the backbone of networks handling high capacity data and multimedia data.

The GS400 complies with IEEE 802.3 10Base-T,IEEE 802.3u100Base-TX,IEEE 802.3ab1000Base-Tand IEEE 802.3x flow control, providing users four ports withauto-negotiationfunction, which can automatically adjust device speeds at 10/100/1000Mbps for optimum operation;“Store-and-Forward” architecture filters to eliminate error packets and improve efficiency. Plus, based onAuto-MDI/MDIXtechnology, just use either a straight through or a crossover Ethernet cable, and you can get connected with any other devices.

Equipped with Classes of Service (CoS) and 4 port-basedVLAN that enables control over packet transfers thorough prioritization of data traffic, the GS400 enables flexible network configuration and raises network application availabilities of groupware, databases and so on. All of these expand the range of possibilities on network.


Four 10/100/1000Mbps auto-sensingEthernet ports Complies with IEEE 802.310Base-T,IEEE 802.3u100Base-TXand IEEE 802.3ab1000Base-Tstandards “Store and Forward” architecture

IEEE 802.3x or Back Pressure (HDX) Flow Control Full Aggregate Bandwidth up to 8 Gbps.

8K MAC Address table supported

Four Classes of Service (CoS) selectable per port basis and/or checked via IP header and 802.1Q VLAN Tag Support 4 port-basedVLANs

Configurable to 10 full/half duplex, 100 full/half duplex and 1000 full duplex for each port Broadcast throttling

Port Mirroring for debugging network problems Support on a RS-232Cconsole port for switch configuration change.
