High performance The GS920 Series delivers ultra-fast speed and high performance for today's high-bandwidth applications, such as video, graphics and industrial design, using Gigabit Ethernet.Quality and reliability Allied Telesis is a world leader in unmanaged Ethernet switches, and ships more than 250,000 unmanaged switches every year. Allied Telesis offers both proven reliability and industry-leading quality. Speed/duplex configuration The GS920 Series allows speed and duplex to be set on a per-port basis. This supports older devices where auto-negotiation is not supported, as well as embedded devices which may support a fixed speed/duplex only. Loop detection The Loop Detection feature discovers network loops, and shuts down affected ports. After the loop is resolved, affected ports are automatically returned to active use. Flooding mode Flooding mode allows the easy capture of data streams for troubleshooting and analysis, as they are sent to all ports. Power over Ethernet (PoE) The GS920/8PS supports PoE+ (IEEE 802.3at) and delivers up to 30W per port. Private VLANs Private VLANs isolate ports so that they can only communicate with the uplink port, and other ports in the same VLAN group. The GS920/8PS supports 3 different port groupings for flexible private VLAN deployment.
