Product Information

The GEL-2861 is a L2 managed switches designed for the SMB market. The switches can be deployed in

different target network topologies, from small to large. As well as IPv4 and IPv6 features.
The GEL-2861 includes the best green-saving technologies (IEEE 802.3az and Green-Ethernet). Using the Energy Efficient Ethernet standard, the switch automatically decreases power usage when network traffic is low.
