Power Supply

The AT-FS708LE Ethernet Switch uses an external power adapter that comes standard with the unit.

Store and Forward

The AT-FS708LE switch uses store and forward as the method for receiving and transmitting frames. When an Ethernet frame is received on a switch port, the switch does not retransmit the frame out the destination port until it has received the entire frame and stored the frame in a port buffer. It then examines the frame to determine if it is a valid frame. Invalid frames, such as fragments or runts, are discarded by the switch. This insures that only valid frames are transmitted out the switch ports and that damaged frames are not propagated on your network.

Back Pressure and Flow Control

In order to maintain the orderly movement of data between the end-nodes, an Ethernet switch may periodically need to signal an end- node to stop 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
