Note Power is supplied to the powered devices in the order that the ports are connected or on a first-come-first-served basis until the 65 watt limit is reached. If the switch is power cycled after the PoE devices are connected to the switch ports, the power is supplied to ports 1 through 8 in that order. -
Page 24: Ethernet Switching Basics
Chapter 1: Overview 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 Every hardware device on your network has a unique MAC address. This address is assigned to the device by the device’s manufacturer. -
Page 25: Store And Forward
end node can receive or transmit data, but not both simultaneously, 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 end node 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. -
Page 26: Back Pressure And Flow Control
Chapter 1: Overview Back Pressure To maintain the orderly movement of data between the end nodes, an Ethernet switch may periodically need to signal an end node to stop and Flow Control sending data. This can occur under several circumstances. For example, if two end nodes are operating at different speeds, the switch, while transferring data between the end nodes, might need to instruct the faster end node to stop transmitting data to allow the slower end node to catch... -
