AT-FS708LE Installation Guide Status LEDs Refer to Table 1 for a description of the device LEDs. Table 1 LED Functions LEDs Color Description PWR Green Indicates the switch is receiving power. 100M Green Indicates the port is operating at 100 Mbps. OFF Indicates the port is operating at 10 Mbps. LNK/ACT Green Indicates a valid physical link on the port. Blinking Indicates data is being transmitted or received on the port. FDX Green Indicates the port is operating in full-duplex mode.

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. Inv

An example of this would be when a server operating at 100 Mbps is sending data to a workstation operating at only 10 Mbps. How a switch signals an end-node to stop transmitting data differs depending on the speed and duplex mode of the end-node and switch port. A twisted pair port operating at 100 Mbps port and half-duplex mode stops an end-node from transmitting data by forcing a

The AT-FS708LE supports TX Flow Control only. This means a PAUSE packet will be transmitted to the end-node connection if it receives data faster than it can switch the packets. The AT-FS708LE does not support RX Flow Control, however, and it will not respond to PAUSE packets sent to it by an end-node. Twisted Pair Ports The AT-FS708LE switch has eight 10Base-T/ 100Base-TX twisted pair ports. Each twisted pair port features a RJ-45 connector. The maximum operating distance for the twiste

Duplex Mode Duplex mode refers to the way an end-node sends and receives data on the network. An end-node can operated in either half- or full- duplex mode depending on its capabilities. An end-node that is operating in half-duplex mode can either send data or receive data, but it cannot do both at the same

Note Since the AT-FS708LE ports operate in Auto-Negotiate mode only, the end-nodes connected to the AT-FS708LE must also be configured to operate in the Auto- Negotiate mode. If an end-node is configured to a specific duplex in a manual mode, it will not respond to the Auto-Negotiate protocol from the AT-FS708LE. (The speed is determined from the link pulses, however, so the speed is always detected correctly.) As a result, the AT-FS708LE port setting will end up at half-duplex. If th
