Solid Green A valid 1000 Mbps link is established on the port. Solid Orange A valid 10 or 100 Mbps link is established on the port.
AT-GS900/16, AT-GS900/24 Gigabit eco-friendly Ethernet Switch Installation Guide Ethernet Switching Basics An Ethernet switch interconnects network devices, such as workstations, printers, routers, and other Ethernet switches, so that they can communicate with each other by sending and receiving Ethernet frames. MAC Address Table Every hardware device on your network has a unique MAC address. This address is assigned to the device by the device’s manufacturer.
Chapter 1: Product Description the end-node is operating in what is referred to as half-duplex mode. If an end-node can both receive and transmit data simultaneously, the endnode is said to be operating in full-duplex mode. Naturally, an end-node capable of operating in full-duplex can handle data much faster than an end-node that can only operate in half-duplex mode.
